A process for the preparation of triethylene glycol dicarboxylic acid esters

The invention discloses a preparation method of triethylene glycol dicarboxylate which has a structural formula (I). The method comprises the following step: in the presence of a catalyst containing anhydrous potassium carbonate, triethylene glycol with a structural formula (II) reacts with carboxylate RCOOR1 and R'COOR1 to generate products containing triethylene glycol dicarboxylate with the structural formula (I) and corresponding alcohol HOR1, wherein R and R' are the same or different and are respectively and separately selected from one of linear C2-C17 alkyl groups and branched C3-C17 alkyl groups and C4-C8 naphthenic groups; and R1 is one selected from C1-C5 alkyl groups. The method provided by the invention is beneficial to environmental protection and has advantages of high product yield and good purity.

The acyloin reaction using tethered diesters

A study of the intramolecular acyloin condensation using diesters tethered by their alkoxide groups was undertaken.The goal was to provide a method for optimizing the yield of mixed acyloin products from the reaction of two different esters by utilizing tethered dissimilar esters as substrates.The results of the study show that the yield of the acyloin condensation is dependant on the tether length.Tethers of 8 and 14 carbons in length give yields comparable to those obtained from an intermolecular control reaction while shorter tethers give reduced yields of product.However, the use of mixed tethered diesters and a crossover experiment between two different tethered substrates provides a statistical distribution of products.These observations have been interpreted as resulting from a fragmentation of the initially formed radical anion intermediate that destroys the tethered nature of the substrate(s).
