Paragraph 0062; 0065, (2021/11/27)
The invention discloses an intermediate substance with an acid degradation function and a preparation method of same; whereinthe preparation method of the intermediate substance comprises the following steps: dissolving 2-nitrobenzaldehyde in a proper amount of dichloromethane, if the reaction substance is cinnamyl aldehyde, mixing the substance with trimethyl orthoformate without the help of a dichloromethane solvent with hafnium trifluoromethanesulfonate as a catalyst; then under the condition of room temperature, performing magnetic stirring to obtain the target substance in a very short time. According to the invention, the defects of time consumption, energy consumption, solvent consumption and the like caused by adopting p-toluenesulfonic acid as a catalyst for preparing the substance traditionally are avoided, and the prepared substance has an acid degradation function. Corresponding 2-nitrobenzaldehyde or cinnamyl aldehyde can be obtained through acid degradation, and in addition, the intermediate substance provides convenience for subsequent preparation of polymerizable monomers with an acid degradation function.

Paragraph 0032-0073; 0115-0134, (2021/12/08)
The invention discloses a synthesis method of alkyl (meth) acrylate, and belongs to the field of organic chemical synthesis. The synthesis method of the present invention employs a heterogeneous solid acid catalyst. The polymerization inhibitor and (meth) acrylic acid were put into the reaction kettle and heated to 50 - 90 °C, and an epoxide was introduced into the reaction kettle for reaction. The reaction solution is filtered to remove the homogeneous solid acid catalyst and the rectification to obtain the target product. The synthesis method not only can improve the selectivity of a target product (methyl) acrylic acid alkyl ester, but also can effectively inhibit the generation of high-boiling-point double esters of by-products generated by the addition of bis (methyl) acrylic acid.
A method for synthesis of hea

Paragraph 0018; 0019, (2017/03/08)
The invention discloses a synthesis method of hydroxyethyl acrylate, which comprises the following steps of: adding acrylic acid into a reaction kettle, and then adding into a magnetic zeolite molecular sieve; stirring uniformly, and then adding epoxypropane; heating the reaction kettle to 60-65 DEG C, and reacting for 2-3 hours; and distilling to obtain the hydroxyethyl acrylate. According to the synthesis method disclosed by the invention, by adopting the magnetic zeolite molecular sieve as a catalyst, a polymerization inhibitor is not required, thus the separation and purification of products are facilitated; and moreover, the yield of the hydroxyethyl acrylate can exceed 97%, the catalyst can be recycled, and the synthesis cost is reduced.
