摘要: The present invention relates to a process in which a triglyceride is transesterified with an alcohol in the presence of a solid catalyst. In order to provide a process by means of which a triglyceride can be transesterified with an alcohol in the presence of a solid catalyst in relatively moderate reaction conditions with a good yield and at relatively high reaction rate, it is proposed that the solid catalyst comprises a zeolite X with an Si/Al atomic ratio of less than 1.2.
