3 - (3,5-di-tert-butyl-4-hydroxy phenyl) method for preparing propionic acid different Xin Zhi

The invention provides a method for preparing 3-(3,5-di-t-butyl-4-hydroxyphenyl) propionic acid acrylate. The method includes the steps of adding 3-(3,5-di-t-butyl-4-hydroxyphenyl) methyl propionate, isooctyl alcohol and a catalyst to a reactor, carrying out nitrogen displacement and heating, reducing pressure to extract methyl alcohol generated in a reaction, after the reaction, carrying out cooling, adding polyatomic organic acid to complex and filter the catalyst, distilling excessive isooctyl alcohol in vacuum for cyclic utilization, and obtaining the colorless and transparent product. Compared with the prior art, the method is a green technology which has the advantages that the catalyst can be rapidly and completely removed, aftertreatment technologies are easy and convenient to realize, the three wastes are scarcely produced, and product stability is high.

Processing improvements for hindered, ester-substituted phenols

The present invention related to a novel continuous process for the manufacture of hindered, ester-substituted phenols using 2,6-dialkylphenol a basic catalyst and acrylate esters.

Preparation of sterically hindered hydroxyphenylcarboxylic acid esters

A novel manufacturing process is described for producing hindered phenolic alkyl esters, which may be useful as antioxidants. This process simplifies catalyst neutralization and removal during the preparation of hindered phenolic esters. Compositions that comprise the hindered phenolic esters produced according to these methods are also described.
