  Usage

  Intermediate in the synthesis of polyvinylpyrrolidone, DL-methionine, piperidine, phenylbutyric acid, thiobutyric acids.Solvent for polyacrylonitrile, cellulose acetate, methyl methacrylate polymers, polystyrene.Constituent of paint removers, textile aids, drilling oils.

  Production Methods

  The preparation method is based on 1, 4-butanediol, preheated first, and reacted with hydrogen in the presence of a copper catalyst, the temperature is controlled at 230-240°C to obtain crude γ-butyrolactone, which is obtained by vacuum distillation product. At present, the maleic anhydride method has been used to obtain succinic anhydride through hydrogenation, and further hydrogenation and dehydration to obtain products. research chemicals for sale
