Paragraph 0093-0106; 0128-0132, (2021/11/02)
More particularly, the present invention relates to an acrylate monomer having a high-purity hydrophilic terminal group which does not contain unreacted 1 water or undesirable by-products, and a method for producing the acrylate monomer. These acrylate monomers are substantially free of polymerization inhibitors. Chemical Formula 1. In Chemical Formula 1, R. 1 Chem. R. 2 Chem. R. 3 May be H, or linear, branched or cyclic C, independently of each other. 1 -C12 alkyl group. R4 Is linear, branched or cyclic C. 1 -C12 alkyl Or C1 -C12 It is alkoxy group, wherein alkyl group carbon atoms can be unsubstituted or substituted with oxygen atoms, n Is an integer selected from 1 and 10.

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

Paragraph 0033; 0034, (2017/07/14)
Hydroxyethyl (methyl)acrylate is prepared by a process of a combination of a three-stage tubular reactor and a tower reactor, wherein, firstly, a catalyst, a polymerization inhibitor and (methyl) acrylic acid are mixed until the solids are dissolved, then mixed with a part of ethylene oxide and thereafter enter into a first tubular reactor for a reaction, a reaction liquid flowing out from the first tubular reactor is mixed with a certain amount of ethylene oxide and enters into a second tubular reactor for a reaction, a reaction liquid flowing out from the second tubular reactor is then mixed with a certain amount of ethylene oxide and thereafter enters into a third tubular reactor, and a reaction liquid flowing out from the third tubular reactor is then passed through a stage of an adiabatic tower reactor and aged such that a product liquid is obtained from extraction.
