Abstract

Vat-dyes are produced by alkali fusion of the condensation products of acenaphthenone with arylaldehydes having the constitution:- <FORM:0233452/2/1> According to examples, blue and grey vat dyestuffs are obtained by potash fusion of benzylideneacenaphthenone and o-oxybenzylideneacenaphthenone (from salicylaldehyde) respectively. a -Naphthylideneacenaphthenone in a similar manner yields a greyish-blue dyestuff, and the condensation product from acenaphthenone and anthraquinone-2-aldehyde a blue dyestuff; condensation products from other aldehydes, for example chloro-, oxy-, or amino-aldehydes may also be used. The properties of the condensation products from acenaphthenone and salicylaldehyde, a -naphthaldehyde, and anthraquinone-2-aldehyde are also given.
