We present here for the first time a novel environmentally benign protocol for the synthesis of vinyl ester resin (VER). Our synthetic strategy utilizes a commercial waste material, glycerin, from biodiesel manufacturing and converts it into a widely utilized resin. The VER was synthesized using bisphenol A (BPA) and glycidyl methacrylate (GMA) as precursors. GMA was synthesized via a multistep synthetic protocol using glycerin obtained from a biodiesel manufacturing waste stream. The structure of the intermediates was confirmed by 1H NMR, HPLC and FT-IR spectroscopy.

(Methyl) acrylic acid ether hydroxyl alkane ester synthesis method
-
Paragraph 0027, (2019/08/07)
The invention relates to the field of organic synthesis and discloses an (methyl) acrylic acid ether hydroxyl alkane ester synthesis method. The method includes steps: subjecting methyl acrylic acid and epoxy chloropropane to reaction to generate acrylic ester with an epoxy group; subjecting the epoxy group to positioning and ring opening to enable a hydroxyl at 2-site carbon and a sterically hindered ether bond at a 3 site; subjecting to reaction with a primary alcohol compound to generate a target product. The method has advantages that side reactions in a synthesizing process are less, polymer crystallinity can be changed, mechanical performances such as tensile strength of a polymer are enhanced, and the hydrophilic performance can be changed.

Paragraph 0015; 0016, (2016/11/14)
The invention relates to a production method of glycidyl methacrylate. The method comprises a reaction process and a post-treatment process. The reaction process is characterized in a one-step synthesis method. According to the reaction process, methacrylic acid and sodium carbonate are subjected to a neutralization reaction in excessive epichlorohydrin, such that sodium salt is prepared; without solid-liquid separation, system water content is removed with an azeotropic solvent; under the catalysis effect of a phase transfer catalyst, the glycidyl methacrylate is prepared. The post-treatment process comprises the following steps: a reaction finished liquid is washed; liquid separation is carried out, such that an organic phase is obtained; solvent recovery is carried out with a film evaporation device; and finished product distillation is carried out with a molecular distillation device. With the production method provided by the invention, production process and industrial equipment can be simplified, and operation is convenient. During the post-treatment process, phenomena of poor product polymerization rate and yield caused by high temperature, poor heat transfer effect, low distillation efficiency and the like of a conventional kettle distillation method can be avoided. With the method provided by the invention, product quality and yield can be effectively ensured. The obtained product has a purity higher than 98% and a yield of 85-90%.
