Abstract

Synthesis of tributyl citrate with carbylic sulfoacid catalyst is carried out by taking carbylic sulfoacid as catalyst while ester synthesizing, filtering, decompress distilling the filtrate to obtain tributyl citrate and circulation using the filtered carbylic sulfoacid. It is cheap, short reactive time and gentle reactive condition, has more yield and higher activity.

Description

technical field

[0001] The invention relates to the technical field of organic chemical synthesis, in particular to a method for catalyzing and synthesizing tributyl citrate with carbonyl sulfonic acid. Background technique

[0002] Tributyl citrate is a non-toxic and tasteless "green" environmental plastic plasticizer, widely used in food and medical instrument packaging, cosmetics, daily necessities, toys, military supplies, etc., with good compatibility, high plasticizing efficiency, no It has the advantages of toxicity, easy biodegradation and low volatility, excellent cold resistance, light resistance and water resistance, and has mildew resistance in the resin, and does not grow mold. The combination of tributyl citrate and other non-toxic plasticizers can increase the hardness of the product, especially for soft fiber ether. At the same time, it can improve the anti-ultraviolet ability of nitrocellulose, and is a solvent for various spices, and can also be used as a ...
