Carbon tetra-chloride

A solution prepared by dissolving 2 g. of biomine in 100 g. of carbon tetra. chloride is satisfactory. Carbon tetrachloride is employed because it is an excellent solvent for bromine as well as for hydrocarbons it possesses the additional advan. tage of low solubility for hydrogen bromide, the evolution of which renders possible the distinction between decolourisation of bromine due to substitution or due to addition.

Strength of the solution, in terms of iodine, is determined by titration. The iodine solution is added to the fat or acid dissolved in chloroform or carbon tetra-chloride, and the absorption allowed to take place. After the absorption is completed the excess of iodine is determined by titration and the amount actually absorbed is calculated per 100 grams of the fat or acid used. The iodine values, as thus determined, for some of the common fats and oils are given in the following table. It will be noticed that, with the exception of cocoanut oil and cocoa butter, butter fat has the lowest value of the common fats and oils. [Pg.215]

Viscose Silk.—III. From Cellulose Xanthate. We have referred to the solvent action of xanthic acid, which is the ethyl ether of di-thio-carbonic acid, viz., HS-CS-OC2H5. When sodium cellulose is dissolved in xanthic acid the cellulose is in the form of sodium cellulose xanthate. A solution properly prepared by treating cellulose with sodimn hydroxide and carbon di-sulphide in the presence of benzene or carbon tetra-chloride, in which polymerization of the cellulose compound is effected, is decomposed by forcing capillary streams of the solution into a solution of ammonium sulphate. The cellulose is thus obtained as in the other processes in the form of fine filaments of a hydrated cellulose possessing silk-like properties. Artificial silk of this type is known as viscose silk and is made in large quantities. In 1914 about 20,000,000 pounds of artificial silk were made, of which about 3,000,000 pounds were made in the United States. Most of this product was viscose silk. [Pg.374]

The principle of- this reaction allows the synthesis of hydroxy acids if instead of chloroform we use carbon tetra-chloride, CCI4. [Pg.718]

Properties of Pure Caoutchouc.—Pure caoutchouc may be obtained by dissolving rubber in certain solvents, after first removing resins by solution in acetone. The rubber free from resins is treated with chloroform, benzene, or carbon tetra-chloride, all of which are solvents of caoutchouc. Evaporation of the solvent leaves j ure caoutchouc. [Pg.843]
