What's the difference between leucaniline and rosaniline?
Leucaniline
Definition:
(n.) A colorless, crystalline, organic base, obtained from rosaniline by reduction, and also from other sources. It forms colorless salts.
Example Sentences:
Rosaniline
Definition:
(n.) A complex nitrogenous base, C20H21N3O, obtained by oxidizing a mixture of aniline and toluidine, as a colorless crystalline substance which forms red salts. These salts are essential components of many of the socalled aniline dyes, as fuchsine, aniline red, etc. By extension, any one of the series of substances derived from, or related to, rosaniline proper.
