Abstract

1375652 Preparation of pyranthrones BADISCHE ANILIN- & SODA-FABKIK AG 28 March 1972 [29 March 1971 (2)] 14438/72 Addition to 1318768 Heading C4P Pyranthrones are prepared by heating a 2,2<SP>1</SP> - 1,1<SP>1</SP> - dianthraquinonyl at 90-210‹ C. in a polar organic solvent which may contain up to 20% by weight of water on the amount of solvent in presence of 0À1 to 3À0 moles per mole of the dianthraquinonyl of an alkali metal formate, alkali metal salt of a C 3 -C 20 aliphatic carboxylic acid, a cycloaliphatic, aromatic or heterocyclic carboxylic acid, an alkali metal salt of carbonic acid, a tertiary alkali metal phosphate, an alkali metal hydroxide or a primary, secondary or tetiary cycloaliphatic amine or mixtures thereof. The solvents include ethylene glycol, diethylene glycol, dipropylene glycol, N-dimethyl-formamide, N,N- dimethylacetamide, N, N-diethylacetamide, N- methyl - pyrrolidone, dimethylsulphoxides or mixtures thereof.
