Abstract： |
The invention publishes a new craft for distilling pamade from raw oil in method of short chain fatty acid and ester as acetone in pomade picked-up technique field. Mix short chain fatty acid and ester RCOOR with crushed raw material containing oil, chatter it for while, draw and strain several times. The things which is drawn contains short chain fatty acid and fatty ester admixture. The short chain fatty acid can be used to replace normal extraction solvent which is distilled from soja, rape seeds and other raw material to distilled promade. The distilled ester admixture can be used to produce biologic diesel oil. The invention can be used to produce biologic diesel oil that short chain fatty acid is used to replace to normal extraction solvent. Not only craft but also cost of manufacture has a bright commercial foreground. |
