Latest Patents

Junhua Zhang holds a patent for a method of preparing hydroxyethyl (meth) acrylate. This process involves a combination of a three-stage tubular reactor and a tower reactor. Initially, a catalyst, a polymerization inhibitor, and (methyl) acrylic acid are mixed until the solids dissolve. This mixture is then combined with a portion of ethylene oxide and introduced into the first tubular reactor for a reaction. The reaction liquid flowing out from the first tubular reactor is mixed with additional ethylene oxide and enters the second tubular reactor for further reaction. This process continues with a third tubular reactor, and finally, the reaction liquid is passed through an adiabatic tower reactor and aged to obtain the final product.
