Process for the preparation of reaction products of epoxidized ricinoleic acid glycerides with sulfur trioxide |
| abstract |
The sulfonation of epoxidized ricinoleic acid glycerides with a dry stream of gaseous sulfur trioxide diluted with a carrier gas, followed by a reaction of the sulfonated reaction product with nucleophiles, leads to salt-free and anhydrous products showing surface-active properties. |
