 fats, sulphur, iodin, and phosphorus. It is 

 material from which anilin and the anilin colors 

 are derived. B.-sulphonic Acid, C, ; I b. S< >.,! I , is 

 ared by boiling together equal parts of benzene 

 and H 2 S0 4 . It occurs in small plates, readily soluble 

 in alcohol and water, and which deliquesce in the air.

 sulphone, and when fused with caustic potash phenol 

 is produced.

 acid on hydrid of benzoyl. It occurs also in the 

 resinous residue of the rectification of the oil of bitter 

 almond-.

 boiling at 8o° to 90 C, colorless, of ethereal odor, 

 and a slightly peppermint-like taste. It is a valuable 

 solvent for oils, fats, resins, caoutchouc, and some 

 alkaloids. It is a vermicide against tapeworm. It 

 should be distinguished from Benzol, which is called

obtained fn native to Sumatra 



and Siam. It is also a ketone alcohol, C, 4 H 12 < >.„ and 

 may be produced by oxidizing hydrobenzoin with con- 

 centrated IIN't ),. It is sparingly soluble in water, cold 

 alcohol, and ether, and crystallizes in shining prism-, 

 melting at 134°- It is used as a remedy for bronchitis 

 and in making court-plaster. It occurs in tears con- 



sisting of several resin- agglutinated by a balsam. It 

 yields benzoic and cinnamic acids, is antiseptic and 

 disinfectant, and is used mainly as a stimulant ex] 

 toranl in chronic bronchitis. Sodium and potassium 

 compounds air sometimes used in place of like salicylic 

 acid compounds. Adeps benzoinatus, benzoinated
