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

1,4-butanediol dimethylacrylate preparation method

The invention provides a 1,4-butanediol dimethylacrylate preparation method. Under the action of a solid catalyst acid sodium bisulphate, in the presence of a polymerization inhibitor and an azeotropic water-carrying agent, 1,4-butanediol and methacrylic acid are reacted at 80 to 90 DEG C for 4 to 7 hours for synthesis to obtain 1 , 4-butanediol dimethacrylate; the molar ratio of methacrylic acidto 1,4-butanediol is 2.10:1, and the amount of n-hexane in the azeotropic water-carrying agent accounts for 50% of the total mass of a reactant, the solid acid catalyst accounts for 3% of the total mass of the reactant, and the amount of the polymerization inhibitor phenothiazine accounts for 0.05% of the total mass of the reactant. the catalyst used in the synthesis method of 1,4-butanediol dimethacrylate is cheap, stable, easy to separate from products, and does not corrode equipment, the 1,4-butanediol dimethacrylate achieves the purpose of clean production, has high yield, and has broad application prospects.

METHOD FOR THE PRODUCTION OF (METH)ACRYLIC ESTERS

The present invention relates to a process for preparing (meth)acrylates, comprising the transesterification of a low-boiling ester of (meth)acrylic acid with a reactant alcohol in the presence of catalysts, which is characterized in that the transesterification is catalysed by a basic ion exchanger.
