AI Technical Summary
Technical Problem
Existing technologies for hydrogen esterification reactions suffer from problems such as a small gas-liquid interface, long reaction time, and the inability to recover the catalyst, resulting in low synthesis efficiency and high cost.
Method used
The synthesis of fatty acid diesters is carried out using a shell-and-tube reactor. The connection between the tube side and the shell side allows the gaseous feedstock to contact the liquid catalyst, and the catalyst is recovered through membrane separation technology, thus achieving continuous production.
Benefits of technology
This improved the conversion rate of raw materials and the selectivity of products, reduced the synthesis cost, and enabled the efficient synthesis of fatty acid diesters.

Abstract
The present application relates to the field of organic synthesis, in particular to a synthesis method of fatty acid diester compounds. The method is carried out in a device, which comprises a shell-and-tube reactor provided with a tube pass for gas passing and a shell pass for liquid passing; the tube pass and the shell pass are communicated through openings on the tube wall, and the openings are limited for gas phase raw materials to pass; the method comprises: feeding a solution containing a catalyst and a terminal diene into the tube pass of the reactor, feeding a gas phase containing CO into the tube pass of the reactor, and part of the CO passes through the openings of the tube wall into the tube pass to react with the solution containing the catalyst and the terminal diene. The present application adopts a specific structure of the reactor to synthesize the fatty acid diester compounds, and has excellent raw material conversion rate, product selectivity and reaction efficiency.
