Abstract:
Apart from the conventional chemical esterification process, long-chain alkyl ricinoleates also can be prepared by enzymatic
esterification or by enzymatic alcoholysis with high yield and without undesirable side reactions. On sulfonation to the hydroxyl
group, the alkyl ricinoleates produce surface-active compounds. The tetradecyl ricinoleate shows the best surface-active behavior
and seems to be much better than that of sulfonated castor oil commonly known as “Turkey Red Oil”.
