1870.] Furjuraniline and Furfur ioluidine, 569 



Furfuraniline liydrochlorate. — The best method of preparing this salt 

 was to dissolve 46 parts aniline and 65 parts aniline hydrochlorate in 400 

 parts of warm alcohol, and then add 48 part3 furfurol, likewise dissolved 

 in 400 parts spirit ; after the solutions were thoroughly mixed, they soli- 

 dified in the course of a few minutes to a mass of crystals of the salt. 

 When cold, these were thrown on to a filter, freed from the mother 

 liquor by means of a vacuum filter, and washed with a small quantity of 

 coloured spirit. They were then readily obtained in a pure state by re- 

 crystallization from boiling spirit. The substance analyzed was dried in 

 vacuo.

It is insoluble in benzol, bisulphide of carbon, and water, but is slowly 

 decomposed when boiled with the latter. It is soluble in boiling 

 spirit, and crystallizes out on cooling in small needles of a fine purple 

 colour, which acquire a metallic lustre on drying. The crystals are per- 

 manent in dry air when light is excluded, but are readily decomposed 

 when boiled with dilute acids or alkalies. 



Furfuraniline 'nitrate. — This is prepared in a manner similar to that 

 employed for the hydrochlorate : 23 parts aniline and 39 of nitrate were 

 dissolved in 200 parts warm spirit, and 24 parts furfurol in 200 of spirit 

 added. The mixture, on being allowed to stand some time, became a 

 semisolid crystalline mass, which was purified in the same manner as the 

 corresponding hydrochlorate.
