摘要:
The present invention provides one-step processes for the production of chlorinated and/or fluorinated propenes. The processes provide good product yield with low, e.g., less than about 20%, or even less than 10%, concentrations of residues/by-products. Advantageously, the processes may be conducted at low temperatures relative to conventional processes, so that energy savings are provided, and/or at higher pressures so that high throughputs may also be realized. The use of catalysts may provide enhancements to conversion rates and selectivity over those seen in conventional processes, as may adjustments to the molar ratio of the reactants.
摘要(中):
本发明提供用于生产氯化和/或氟化丙烯的一步法。 该方法提供良好的产物收率,具有低,例如小于约20%,或甚至低于10%的残余物/副产物浓度。 有利地,相对于常规方法,该方法可以在低温下进行,从而提供节能和/或在更高的压力下,从而也可以实现高产量。 催化剂的使用可以提高转化率和选择性,而不是可以调节反应物的摩尔比。
