The synthesis of novel hybrid monomers

Novel hybrid amide-ester crosslinking monomers were prepared by using methodology which utilizes the differential functionalities present within a convenient amino alcohol. Modification of the procedure to a simple one-pot reaction enables the generation of these unique monomers to be scaled to commercial levels.

Method for producing hydroxyethyl methacrylate through ester exchange method

The invention discloses a method for producing hydroxyethyl methacrylate through an ester exchange method, and belongs to a chemical synthesis method. The method comprises the following steps: using methyl methacrylate and ethylene glycol as raw materials, using p-toluene sulfonic acid as a catalyst, using phenothiazine as a polymerization inhibitor, and performing a reaction under the condition of the temperature of 100-120 DEG C so as to prepare a target product. The method disclosed by the invention is safe and simple; compared with catalysts of hexadecyl trimethyl ammonium hydroxide, potassium cyanide, heavy metallic salt type catalysts and the like, the catalyst used in the method disclosed by the invention, namely the p-toluene sulfonic acid, is lower in price, easier to obtain, easier to store and use, smaller in pollution, and better in cooperation use effect with the polymerization inhibitor, and the method is easy in industrialization application.
