66 PEOPYL ALCOHOLS. 



The derivatives of propyl alcohol are prepared in 

 the same manner as those of ethyl alcohol, and con 

 duct themselves analogously. 



Propyl chloride, C 3 H 7 C1. Colorless liquid, boiling 

 at 52. 



Propyl bromide, C 3 H 7 Br. Liquid ; boiling point, 

 71. 



Propyl iodide. C 3 H 7 I. Liquid; boiling point, 



102. 



Propylether, (C 3 H 7 ) 2 0. Very mobile liquid, boil- 

 ing at 85-86. 



Propylamine, C 3 H 7 .KH 2 . By the action of hydro 

 gen in statu nascendi (zinc and hydrochloric acid) on 

 propionitrile (p. 47), and by the distillation of propyl 

 eyanate with caustic potassa. Clear, strongly refract 

 ing liquid, possessing an ammoniacal odor. Boiling 

 point, 49-50. Mixes with water. Burns with 

 a luminous flame. Strong base. The hydrocMorate, 

 C 3 H 7 .NH 2 .HC1, is deliquescent, also very easily soluble 

 in alcohol. With platinum chloride it yields a double 

 salt (C 3 H 7 .KH 2 .HCl) 2 PtCl 4 , which is pretty easily solu 

 ble in hot water and in alcohol, and crystallizes in 

 large, gold-colored, klinorhombic plates. 



2. Secondary propyl alcohol (Pseudopropyl 

 alcohol), CH 3 .CH.01LCH 3 . Is formed by the action 

 of hydrogen in statu nascendi (from water and sodium- 

 amalgam) on acetone. Colorless liquid, miscible with 

 water in all proportions. Boiling point, 85; specific 

 gravity, 0.791 at 15. Combines with calcium chlo 

 ride, forming a solid compound. By oxidation it is at 

 first reconverted into acetone and then yields acetic 

 and formic acids. 



Pseudopropyl iodide, C 3 II 7 I, is produced by the 

 direct union of propylene with hydriodic acid, and by
