Abstract:
Sulfuric acid semi-esters of oxalkylated polynuclear alkylphenols of the formula
IN WHICH -(OX)- stands for an oxyalkylene radical, R1 for an alkyl radical, X for hydrogen or SO3Me, Me being hydrogen, ammonium, an alkali or alkaline earth metal, n and m for an integer of about 2 to 25 and z for an integer of 1 to about 9, and their use as dispersing and wetting agents for waterinsoluble organic biocidal compositions.
Abstract:
This invention relates to sulfosuccinic acid semi-esters of oxyalkylated polynuclear alkylphenols of the formula
IN WHICH R represents a group of the formula
(OX) represents oxyalkylene radicals, R1 represents an alkyl group having 6 to 14 carbon atoms, Y represents hydrogen or has the same meaning as that given for R , n represents a number from 2 to 25, z represents a number from 1 to 9 and Me stands for hydrogen or an alkali metal, and their use as dispersing and wetting agents for sprayable powders or dispersable concentrates containing water-insoluble organic biocidal agents.
Abstract:
A dye and pigment dispersion containing a sulfuric acid semiester of the formula
IN WHICH X is ethylene or propylene, R1 alkyl of 4 to 14 carbon atoms, R2 hydrogen or alkyl of 4 to 14 carbon atoms, n an integer of 2 to 25, z zero or an integer of 1 to 8 and Me hydrogen, alkali, alkaline earth metal, an ammonium ion or a radical of an organic base, and a process for preparing it by grinding the dye or pigment in the presence of an aqueous solution of said sulfuric acid semi-ester. The dispersing agents obtained have a good dispersing effect and tinctorial strength and give a neutral reaction in contrast to most of the known anionic dispersing agents.
