Claims21
As novel compounds sulphoperoxyacids having the following formula (1):
- ##STR10## in which R' bonds the percarboxylic acid substituent directly to the benzene nucleus or represents an alkylene group, R" represents at least one alkyl group and the total number of carbon atoms in R'+R" is from 4 to 18, R' and R" optionally forming a cycloalkyl group, and in which the --CO.sub.3 H and --SO.sub.3 M substituents are separated by at least 3 carbons linearly, and M represents an alkali metal.
A novel sulphoperoxyacid selected from 3-sulpho-4-n pentyl-perbenzoic acid, monopotassium salt.
A novel sulphoperoxyacid selected from 3-sulpho-4-n pentyl-perbenzoic acid, monopotassium salt.
A novel sulphoperoxyacid selected from 6-(3-methyl-4-sulpho-phenyl)-perhexanoic acid, monopotassium salt.
A novel sulphoperoxyacid selected from 6-(3,5-dimethyl-2-sulpho-phenyl)-perhexanoic acid, monopotassium or monosodium salt.
A novel sulphoperoxyacid selected from 6-(1,2,3,4-tetrahydro-7-sulpho-naphthalene)-perhexanoic acid, monopotassium salt.
