Abstract

The process of the parent Specification, according to which benzanthrone or its substitution products not substituted in the 11-position are condensed with aromatic acid chlorides, is applied to benzanthrones substituted in the 11-position (now designated in the 2-position). According to an example, dyestuffs dyeing cotton in yellow shades from a red vat are prepared by heating 2-methylbenzanthrone (of M.Pt. 199 DEG C.) or 2-chlorbenzanthrone (obtained from 2-chloranthraquinone by the usual methods) with benzoyl chloride, aluminium chloride and zinc chloride.
