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

Nucleophilic acyl substitutions of esters with protic nucleophiles mediated by amphoteric, oxotitanium, and vanadyl species

(Chemical Equation Presented) A diverse array of oxometallic species were examined as catalysts in nucleophilic acyl substitution (NAS) reactions of methyl (or ethyl) esters with protic nucleophiles. Among them, oxotitanium acetylacetonate (TiO(acac)2) and vanadyl chloride (VOCl 2-(THF)x) served as the most efficient and water-tolerant catalysts. Transesterifications of methyl and/or ethyl esters with functionalized (including acid- or base-sensitive) 1° and 2° alcohols can be carried out chemoselectively in refluxed toluene or xylene in a 1:1 substrate stoichiometry using 1 mol % catalyst loading. The resultant products were furnished in 85-100% yields by simple aqueous workup to remove water-soluble catalysts. The new NAS protocol is also amenable to amines and thiols in 74-91% yields, albeit with higher loading (2.5 equiv) of protic nucleophiles. Representative examples of commercial interests such as Padimate O and antioxidant additives for plastics were also examined to demonstrate their practical applications. A 1:1 adduct between TiO(acac)2 and a given 1-octadecanol was identified as (C18H37O) 2Ti(acac)2 and was responsible for its subsequent NAS of methyl esters.
