Runge-Kutta analysis for optimizing the Zn-catalyzed transesterification conditions of MA and MMA with diols to maximize monoesterified products

Terminal hydroxylated acrylates and methacrylates were prepared by catalytic transesterification of acrylates and methacrylates with diols catalyzed by a system of a tetranuclear zinc alkoxide, [Zn(tmhd)(OMe)(MeOH)]4 (1a), with 4 equiv. of 2,2′-bipyridine (L1). The reaction time to reach the equilibrium state was analyzed by kinetic studies and a curve-fitting analysis based on the Runge-Kutta method for optimizing the best reaction conditions for mono-esterification. In addition to these kinetic analyses, DFT calculations estimated a proposed mechanism of the catalytic transesterification. This journal is

Method for preparing 4-hydroxybutyl acrylate by means of extraction and separation

The invention relates to a method for preparing 4-hydroxybutyl acrylate by means of extraction and separation. The method is characterized by comprising the following steps: (1) putting 1, 4-butanediol, a catalyst, a polymerization inhibitor and a solvent into a reactor to form mixed liquid; (2) slowly heating and controlling the temperature to be 40-60 DEG C, and dropwise adding acrylic acid containing a certain amount of the polymerization inhibitor for 30-50min at the temperature; (3) continuously and slowly heating and controlling the temperature to be 100-120 DEG C, carrying out a refluxreaction for 2-5h reaction and then finishing the reaction; (4) adding aqueous solution into the mixed liquid and then adding a certain amount of extractant for firstly extracting 1, 4-butanediol diacrylate from an aqueous phase; (5) extracting the 4-hydroxybutyl acrylate from the aqueous phase by using an extractant; (6) distilling under reduced pressure to obtain a finished product. The productof the method is colorless and does not need to be faded, so that the aftertreatment process is simpler, and the quality and yield of the final product are increased.
