66 PROPYL 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, hoiling 

 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 .NH 2 . By the action of hydro- 

 gen in statu nascendi (zinc and hydrochloric acid) on 

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

 cyanate 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 kydrochlorate, 

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

 in alcohol. "With platinum chloride it yields a double 

 salt (C 3 H 7 .E"H 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), CIP.CH.OH.CH 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 hy dried ic acid, and by
