Castor oil can be sulfonated directly with SO 3 in commercially available continuous and batch equipment. The product has good color, excellent water solubility and improved acid stability. The process has the following advantages. It is more direct and considerably faster than the present process. It requires fewer man hours and, therefore, is more economical. Conditions can be varied to give a wide range of products having different solubility characteristics and combined SO 3 content. Since the reaction, batch or continuous, is stoichiometric, no waste products are formed, thus eliminating any pollution problems.
