| Abstract: | Using vaccum distillation followed by soaponification and extraction of the distillates, the quality of naphthenic acid can be improved from Grade 2 to Grade 1. The product is met the specification of refined naphthenic acid used in paint industry and production of esters. A product yield of 67 % can be achieved. Based on a lot of experiments, the process conditions were determined. The extractant is cheap and can be used circularly. |
