Japanese Patent JPS5519215
Kind Code:
B2
Abstract:
This invention concerns the preparation of oxirane compounds by the vapor phase cracking of hydroxyesters in the presence of a basic material. Specifically, it has been discovered that the aforesaid reaction may be carried out without the prior separation of vicinal glycols, vicinal diesters or both. This is particularly advantageous because vicinal hydroxyesters are frequently formed in combination with these latter materials and the separation thereof is most difficult. Preferably, mixtures of the hydroxyesters, glycols and diesters are first hydrolyzed or esterified in order to increase the hydroxyester content.
