Hong, Seung-Mo; Kim, Oh Young; Hwang, Seok-Ho published the artcile< Optimization of synthetic parameters of high-purity trifunctional mercapto esters and their curing behavior for the thiol-epoxy click reaction>, Quality Control of 112-63-0, the main research area is mercaptopropionic acid trimethylolpropane esterification thiol epoxy click reaction.
The direct esterification reaction between 3-mercaptopropionic acid (3-MPA) and trimethylolpropane (TMP) was conducted in the presence of various catalyst concentrations of p-toluenesulfonic acid (p-TSA) to examine the optimized synthetic conditions needed to produce high-purity trimethylolpropane-tris(3-mercaptopropionate) (TMPMP). The purity of the desired TMPMP and uncompleted side-product reduced as the acid catalyst concentration in this esterification reaction increased while the generation of thioester-based side-product increased. The equivalent ratio between epoxy and the manufactured TMPMP was maintained at 1 : 1 to monitor the curing behavior of the thiol-epoxy click reaction using the DSC technique. The thermal features of the base-catalyzed TMPMP-cured epoxy resin were assessed according to the purity of the TMPMP curing agent.
