Document Type and Number:
Japanese Patent JP2700831
Kind Code:
B2
Abstract:
To obtain highly sulphated fatty acids, hydroxy fatty acids or oxalkylated hydroxy fatty acids, the reaction mixture obtained from the sulphatation of unsaturated fatty acid esters and/or saturated hydroxy fatty acid esters and/or oxalkylated hydroxy fatty acid esters is neutralized, separated if necessary from the brine, diluted with water and hydrolysed at a temperature between 20 DEG C and 160 DEG C after addition of a quantity of lye whose molar content is not greater than that of the organically bound sulphuric acid. After separation of the phases containing the non-sulphated starting products and the highly sulphated fatty acids, the latter are isolated from the aqueous phase.
