Abstract

2.7 - Di - m - chloranilido - 5 : 10 - dichlorpyrene-3 : 8-quinone is converted to a finely-dispersed form by dissolving in a mixture of concentrated sulphuric acid and glacial acetic acid having a content of 10-20 per cent glacial acetic acid, and introducing the solution into water. An example is given. Specification 434,027, [Group IV], is referred to.
