| 摘要 |
The present invention relates to a process for preparing an alkylester of fatty acid with high purity via one-step continuous process by reacting an animal fat and/or vegetable oil with a lower alcohol in the presence of alkali catalyst by passing through a continuous tubular reactor while maintaining a single-phase, removing residual lower alcohol from the reaction mixture and removing residual glycerin, catalyst, etc. by phase separation. In accordance with the present invention, an alkylester of fatty acid can be produced with a high yield of 97% or more via one-step continuous process in a continuous tubular reactor without any limitation in flow types by reacting an animal fat and/or vegetable oil with a lower alcohol in the presence of alkali catalyst and carrying out a simple separating process.
