MM. Pelouze and Cahours on Hydride of Caproylene. 385 



liquid with an ethereal odour. Its composition was found to be 



C 12 H 14 =4 vol. vapour, 



and it is the sixth term in the series of which marsh-gas is the 

 first term. The authors name it hydride of caproylene. It 

 dissolves alcohol, ether, fats, and oils. It takes fire when a light 

 is brought near it, and burns with a fuliginous flame. It is 

 unacted upon either by the strongest sulphuric acid, by anhy- 

 drous phosphoric acid, or by fuming nitric add. Chlorine acts 

 upon it, forming a series of compounds in which 1, 2, 3, 4, 

 and 6 atoms of chlorine replace so many atoms of hydrogen 

 respectively. 



The first of these bodies, C 12 H 13 C1, is the hydrochloric ether 

 of caproylic alcohol. When this body acts upon sulphide of 

 potassium in a closed vessel, chloride of potassium and the sul- 

 phide of caproyle, C 12 H 13 S, are obtained. This is a colour- 

 less limpid oil with a foetid odour, boiling at 230°. By the 

 action of hydrosulphate of sulphide of potassium, a compound, 

 C 12 H 13 S, H S, is obtained corresponding to mercaptan. 



When chloride of caproyle is treated with cyanide of potas- 

 sium, chloride of potassium is formed, and a brown oil, which 

 could not be obtained quite pure, but which appeared to be the 

 cyanide of caproyle. When treated with potash, ammoniacal gas 

 was liberated, and a potash salt formed from which an oily acid 

 was separated on the addition of a strong acid. 



The iodide of caproyle, C 12 H 13 I, is a colourless limpid oil boil- 

 ing between 172° and 175°, with an ethereal odour like that of 

 iodide of amyle. By the action of this substance on acetate of 

 silver, iodide of silver and acetate of caproyle,

are obtained ; by treating this acetate with potash, caproylic 

 alcohol, C 12 H 14 2 , is formed. When chloride of caproyle is 

 heated in a closed tube with an alcoholic solution of ammonia, 

 the base caproylamine, C 12 H 15 N, is produced. It is a colourless 

 limpid liquid, with an aromatic ammoniacal odour, and a caustic 

 burning taste. It boils between 124° and 128°. In this action 

 there is also formed a quantity of the base dicaproylamine,

 C 12 H 13 >N. It boils at 190°, and has a less ammoniacal odour

than the caproylamine.
