Sugar (cane Sugar, Sucrose, or Saccharose). C.-H^O,,. This occurs in the juice of sugar cane, sugar beet, maple, palm trees, and many other plants. It forms monoclinic crystals, sp. gr. 1.61, mpt. 160° C; at 200° C. it is converted into CaraMel (q.v.). At 0° C. it is soluble in half its weight of water; at 50° C. it is soluble in ^ its weight of water. Its water solution is Lsvorotatory (q.v.). It is insoluble in absolute alcohol; with dilute alcohol it increases with the dilution. Acids and ferments invert it into dextrose and laevulose. This must take place before fermentation with yeast will take place. It is determined in water solution by a POLARISCOPE (q.v.).

The world's production of cane sugar in the year 1894-95 was estimated at 3,436,700 tons; Europe produced 4,866,000 tons of beet sugar and the U. S. ab. 30,000 tons. Of cane sugar Cuba produced 975,000 tons and the U. S. 285,000 tons. The U. S. also produce ab. 20,000 tons of maple sugar. India produces 100,000 tons of palm sugar.

Sugar, Beet. The sugar beet is the result of cultivation, oeing derived from the wild Beta maritima, several varieties having been developed. It flourishes best in a northern temperate climate. The beets weigh from 1.5 lbs. to 2 lbs. and contain from 10 to 15 per cent of sugar. They are reduced to a pulp by circular saws, 25 per cent of water is added and the juice expressed by a hydraulic press, or extracted by the diffusion process. An excess of lime is added to the juice to neutralize acidity and precipitate the coloring matter; carbon dioxide is passed through to precipitate the lime and the whole is clarilied by a filter press. The solution is then concentrated in a vacuum pan to crystallization. The yield in Germany is from 1,500 to 2,300 lbs. per acre, and in France, up to 2,700 lbs. The molasses is too saline for food and is used in making alcohol. Sugar was produced from the beet in Germany 1798 by Achard, in France 1782 by Rosier, in the U. S. 1830: in the latter were five factories in 1895.

Sugar, Cane. Saccharum officinarum. This was cultivated in India before the Christian era; the boiling of sugar was practiced on the Ganges in the 7th century. The Arabs first practiced sugar refining in the 7th century, and also carried the cultivation of the cane along the Mediterranean to Spain. The Spaniards carried it to San Domingo 1494. It was introduced into the U. S. 1791. Sugar cane flourishes best in subtropical countries. The cane, whole or in cuttings 2 ft. long, is laid in furrows 4 to 6 ft. apart in W. Indies, 8 ft. apart in Louisiana; the plants are from 2 to 5 ft. apart. In the W. Indies the planting takes place in the fall, the crop being gathered in the spring; in Louisiana the reverse of this. The young canes grow from the joints of the cane. Two or three annual crops are obtained from a planting in the U. S.; in the W. Indies as many as fifteen. The plant is from 6 to 15 ft. high, and from 1 to 2 in. diameter. The contents of sugar is from 12 to 18 per cent, of which up to 86 per cent is obtained by the mill, and by the diffusion process up to 95 per cent. The cane juice is expressed by passing between heavy rolls of the sugar mill, or it is extracted by the diffusion process. For the latter the cane is cut into chips and placed in a series of iron vessels, with perforated bottoms, each holding 2 tons. Water passes from one vessel to the next, and so on through theseries; the cane in the first vessel being nearly exhausted and the 'last vessel having fresh cane, the solution thus becoming concentrated. The first vessel is then refilled with cane and becomes the last of the series, and what was the second becomes the first, and so on. This process is used to a limited extent with cane, but is largely used with beets. The juice is now strained and milk of lime added to it in a clarifier to neutralize the acidity and heated to 140° F. to coagulate the albuminous substances. It is then boiled down to crystallizing point in a series of copper pans, baled into a cooler and then into molds to crystallize. In 18 hours the plug in the bottom of the mold is drawn and the molasses drained off, the last being forced out by water from a layer of moist clay laid upon it. For muscovado the sugar is transferred from the cooler into hogsheads, the molasses draining from holes in the bottom. On some plantations the juice after skimming is run through bag- and bone-black filters for decolorization, concentrated in a vacuum-pan and, after crystallizing, the sugar is freed from molasses by a centrifugal machine. The yield of sugar per acre reaches 2,000 lbs. in the U. S., and 5,000 lbs. in W. Indies. The molasses consists of a solution of saccharose, dextrose and Irevulose with saline substances of the juice. The first two are about equally sweet, the dextrose is less sweet, 3 parts being equal to 2 parts of the others.


Sugar-cane (Saccharum ojfficinarum).

Sugar, Maple. This is obtained from Acer saccharinum of temperate climates. Two holes are bored in the tree two fett above the ground on the southern side and reeds or metallic spiles are introduced. The sap runs from February to April, and contains an average of 3.5 per cent sugar, requiring4gals, of sap for 1 lb. of sugar. It is evaporated in an open pan, flowing through devious furrows over it. The average yield of a tree per year is 3 lbs. besides the syrup; the trees last up to 80 years.

Sugar, Palm-tree. This is obtained from several species of palm trees in India. The trees are tapped as with the maple, and the season is from November to February. A good tree yields 30 lbs. of sugar a year and lasts up to 30 years.

Sugar, Sorghum. Sorghum saccharatum has been cultivated in the U. S. since 1853. It was originally from Africa. It contains up to 15 per cent of sugar. The presence of gum, starch and other substances interferes with the crystallization of the sugar. By adding alcohol to the somewhat concentrated juice, these substances are precipitated. After filtering the juice can be concentrated to crystallization. During the payment of sugar bounties, 1892-94, the average crop was 5.3 tons of cane per acre, yielding 82.5 lbs. of sugar per ton, equal to437 lbs. of sugar per acre. 3,000,000 lbs. were produced 189294. Without the bounty this would not be profitable, and molasses with some incidental sugar is made. See SORGHUM.

prevent free access of air. The pile is ignited, a part of the sulphur burns; the heat thus generated is sufficient to melt the rest of the sulphur, which runs down to the bottom of the pile. At proper intervals it is drawn off. The crude brimstone thus obtained is distilled and run into molds, forming roll brimstone or stick sulphur. In the distillation the vapor which is first cooled is deposited as a fine powder, called flowers of sulphur. Stick sulphur is soluble in carbon disulpliide; the flowers of sulphur is not. It is amorphous. Treated with oxidizing agents, it forms sulphuric acid. It is used for the manufacture of sulphuric acid, gunpowder, fireworks, matches, bleaching, and for vulcanizing rubber. Native sulphur abounds in regions of active and of extinct volcanoes, and also in connection with beds of gypsum or about the outlets of sulphur springs. Sicily has long furnished most of the native sulphur used in Europe and America.

Sulphuric Acid. HaSO,. Sp. gr. 1.85, mpt. —26° C, bpt. 327° C. It distills without decomposition; it is a colorless, oilv looking liquid when pure, and one of the strongest acids. It was known to the alchemists, Geber having made it from alum and Valentine in the 15th century by distilling ferrous sulphate. Its composition was determined by Berthellot 1782. The use of niter with sulphur was proposed 1740 by Lefevreand Lemery, and leaden chambers by Dr. Roebuck 1746, the absorption towers bv Gav Lussac i825, and the Glover tower bv John Glover 1850. The use of pyrites dates from 1838. This acid is more largely used in the arts than any other. The strongest acid is used in making nitro-compounds and refining gold and silver; oil of vitriol in refining petroleum; tower and chamber acids in making superphosphates for fertilizers and a very large variety of manufactures. Most chemical industries make use of or are dependent upon it. 90 per cent of the world's product is used in the soda and superphosphate processes. England's product in 1878 was estimated at 850,000 tons, about half the world's product.

Sulphuric acid is made by burning sulphur or iron pyrites in a furnace with access of air, the oxygen of the latter converting the sulphur into sulphur dioxide. This is conducted, together with vapors of nitric acid, through a Glover tower filled with pieces of quartz or earthenware, and then through a series of large, sheet-lead chambers, into which steam or a spray of water is introduced. In these the sulphur dioxide is oxidized to sulphur trioxide by the nitric acid and combining with the water forms sulphuric acid. The waste gases from the last chamber, consisting of nitrogen and its oxides with a little sulphur dioxide, pass through two leaden Gay Lussac towers filled with coke over which sulphuric acid 1.7 sp. gr. drips; the lattercombines with the nitrogen trioxide.tetroxideand pentoxide. The lower oxides and nitrogen are not combined and pass out the chimney connected with the last tower; this chimney serves to draw the gases through the entire apparatus. The loss of nitrogen in the lower oxides is compensated bv the nitric acid, made from sodium nitrate and sulphuric acid, which is intro

Fuming sulphuric acid, H„S,0,, sp. gr. 1.9, solid at 0° C, fumes in the air and is very corrosive. It was known in the 15th century. This is made in Bohemia by oxidizing pyrites ■contained in slate by exposure to moist air to iron persulphate and distilling the product in clay flasks, the acid passing off. It is also made by Winkler's process by passing sulphur dioxide and oxygen over platinized asbestos, where it is oxidized to sulphur trioxide, which is dissolved in sulphuric acid. This ucid is used for dissolving indigo, and in the manufacture of aniline and anthracene dyes.
