This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1889 edition. Excerpt: ...the fibre is coloured greenish yellow, but the original colour is restored on washing with water. Ammonia decolourises, caustic soda turns it red-violet and gradually decolourises it. A mixture of stannous chloride and hydrochloric acid gives a greenish yellow to yellow colour. Regina-purple. This colouring matter consists of the acetate of orthotolylpararosaniline, and is obtained by acting upon the product which distils over in the manufacture of magenta by the arsenic acid process with magenta base and acetic acid at 120. It forms a green powder which dyes a red shade of violet. Benzyl-rosaniline-violet. (Methyl-violet 6B.) On heating methyl-violet with benzyl chloride, C6H5CH2Cl, alcohol, and soda or lime, in a vessel provided with an upright condenser, part of the methyl groups are replaced by benzyl, C7H7, and a series of bases is formed, of which the first members are--C19H13(CH3)4(C7H7)N3OH and C19H13(CH3)3(C7H7)2N3OH. The excess of alcohol and benzyl chloride is distilled off, and the colouring matter is purified in the usual manner, by salting out, etc. It comes into commerce as the hydrochloride or the zinc double salt. The highest benzylated product is marked 6B, and between it and methyl-violet are 2B, 3B, 4B, 5B, produced by mixing the brand B and 6B. Benzyl-violet is very similar in its reactions to methylviolet. It gives somewhat bluer colours. Detection on the fibre.--Treated with caustic potash ley, methyl-violet becomes red-violet; benzyl-violet, light-blue. Both are decolourised on standing. It may he obtained by the action of perchlormethyl formiate or dimethylaniline in presence of aluminium chloride. It is also formed, according to another method, by the action of carbon oxychloride COCl2 on...
