| Abstract: | The components of underlayer glycerin solution from biodiesel preparation with rapeseed oil and soybean oil by means of KOH catalysis and transesterification were analyzed. The main constituents are glycerin, methanol and fatty acid soap in the underlayer glycerin solution; the fatty acid methyl estyers and KOH are its minor constituents. Then the separation method of the underlayer glycerin solution was explored. The separated methanol and fatty acid can be used as the raw material of biodiesel preparation. The content of separated glycerin meets the requirement of analytical regeant. |
