摘要

2072094 9106532 PCTABS00005 Light-coloured sulphonated products with low viscosity, a high organically bound sulphur content and a high sulphonate content are obtained by reacting unsaturated fatty acid mono-, di- and triglycerides with gaseous sulphur trioxide, neutralization with bases, subsequent heating during phase separation, and removal of any unsulphonated starting product. These products are characterized by good surface-active properties.
