Problems solved by technology

Domestic and foreign studies on the modification of animal and vegetable oils and fatty acid esters mainly use catalysts such as p-toluenesulfonic acid and strong acid ion exchange resins. The above catalysts have the disadvantages of polluting the environment, not being reusable, and complicated post-processing steps.
The application of ionic liquids to the modification of animal and vegetable oils, waste oils and fatty acid esters and the direct addition of them to stamping and drawing oils has not been reported yet.
