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 than 500° C. so that energy savings are provided, and/or at higher pressures so that high throughputs may also be realized. The use of catalysts or initiators may provide additional enhancements to conversion rates and selectivity, as may adjustments to the molar ratio of the reactants.
本发明提供了用于生产氯化和/或氟化丙烯的一步法工艺。这些工艺提供了良好的产品产量,残留物/副产品的浓度低,例如低于约20%,甚至低于10%。优点是,这些工艺可以在低于500°C的低温下进行,从而提供节能,并且可以在较高的压力下进行,以实现较高的产量。使用催化剂或引发剂可能会提供对转化率和选择性的额外增强,调整反应物的摩尔比也可能有所帮助。
