Process for treating fatty acids |
摘要 |
A mixture of branched fatty acids containing 18 carbon atoms such as commercial iso-stearic acid is treated to lower the freezing point to below -10 DEG C., by mixing with urea and a lower alcohol, such as methanol, and filtering. The product is useful in the production of low freezing point esters for use as lubricants.
