Abstract

[1-(p-trimethyl ammonium n-propylamidesulphonyl phenyl)-3-(p-chlorophenyl)-pyrazoline] methyl sulphate is prepared by quaternising 1 - (p - dimethyl - amino-n-propylamidosulphonyl - phenyl) - 3 - (p-chlorophenyl) pyrazoline with dimethyl sulphate in a chlorobenzene solution at 80 DEG -95 DEG C. Specification 808,113 is referred to.ALSO:Fibrous materials, e.g. wool, cellulose acetate, polyamide and polyacrylonitrile fibres, are brightened by treating them with a di- or tri-aryl-pyrazoline compound containing a quaternary ammonium group. Suitable brightening agents, which are preferably applied from an aqueous bath, are 1,3-diphenyl- and 1,3,5-triphenyl pyrazoline compounds which contain a quaternary ammonium group bound to the 1- or 5-positioned phenyl radical either directly or via a bridge member, e.g. an alkylene, -O-alkylene, -SO2-alkylene or -SO2-NH-alkylene radical. The phenyl radicals may be further substituted by substituted or unsubstituted alkyl radicals or halogen atoms. Numerous examples of suitable brightening agents are given. Specification 808,113 is referred to.
