| titleOfInvention | Basic perinone dyestuffs and processes for their manufacture |
| abstract | The invention comprises basic perinone dyes of the general formula <FORM:1112734/C4-C5/1> wherein A and B are aryl residues, e.g. benzene or naphthalene condensed with the heterocyclic ring system in the ortho or peri positions, "alk" is an alkylene group, preferably having one or two carbon atoms, R1, R2 and R3 are each alkyl or aralkyl residues or together with the N atom may form a heterocyclic ring, e.g. pyridinium, and X is an anion. They are prepared by reacting an appropriate halogeno-acylperinone having a group =B-CO-alk-halogen with an excess of a tertiary amine N(R1)(R2)R3 (or pyridine), or with a theoretical amount of amine in presence of an inert solvent e.g. dimethylformamide. The anion X may be derived from halo-acids, sulphuric, phosphoric, formic, acetic, chloro-acetic, oxalic, lactic or tartaric acids and double salts with zinc or cadmium chlorides may be obtained. The dyes give orange-red shades on tannined cellulose, silk, hair, leather, polyacrylonitrile or polyvinylidene cyanide.ALSO:Phthaloperinone is worked into a sludge with carbon disulphide and then reacted with chloracetyl chloride and aluminium chloride at room temperature for 10-15 hours with stirring. The carbon disulphide is decanted and the residue decomposed by adding ice. The chloracetyl compound which separates is filtered and dried. |
