Abstract

1,173,943. Substituted pyrazolones. ILFORD Ltd. 30 May, 1968 [12 June, 1967], No. 27034/67. Heading C2C. [Also in Division G2] The invention comprises substituted pyrazolones of the general formula where at least two of X 1 , X 2 and X 3 are chlorine or bromine atoms, the other X if not a chlorine or bromine atom being a hydrogen atom, Q is either a group -NH-Y-R, where Y is either a direct linkage or an acyl linkage selected from -CO.CH 2 .NH- or a group of the formula and R is an acyl group containing an alkyl group of at least ten carbon atoms and a free sulphonic or carboxylic acid group, or Q is a group -N#(T), where T is an acyl group containing an alkyl group of at least ten carbon atoms and is attached to the nitrogen atom by a cyclic imide linkage. The compounds may be prepared by reacting a compound of the formula where X 1 , X 2 and X 3 have the meanings assigned to them above and B is a hydrogen atom, the group -CO.CH 2 .NH 2 or a group of the formula with the appropriate acylating agent. Examples describe the preparation of a large number of compounds where the halogen represented by X is chlorine and where Q is #-(N-n-octadecylisobutyrylamino)- # - carboxypropionylamino, 4 - (4 - dodecylphenylaminocarbonyl) phthalimide, # - (N - 4 - n - dodecylphenyl - acetylamino) - # - carboxy propionylamino, N - (4- dodecylphenyl) pyromellitic di - imide, 3-[#- (N - n - octadecyl - isobutyrylamino)- # - carboxypropionylamino] benzoylamino, 4 - (4- dodecylphenylaminocarbonyl) - N - (aminocarbonylphenyl) phthalimide, N - (4 - dodecylphenyl) - N<SP>1</SP> - (aminocarbonylphenyl) pyromellitic di-imide, 3 - [# - (N - 4 - n - dodecylphenylacetylamino) - # - carboxypropionylamino] benzoylamino, or N - (4 - dodecylphenyl)-N<SP>1</SP>- (4-aminocarbonylphenyl) pyromellitic di-imide.
