    • A process for the manufacture of 1-chloro-3,3,3-trifluoropropene (HCFC-1233zd) at commercial scale from the reaction of HCC-240 and HF is disclosed. In one embodiment, HCC-240fa and HF are fed to a reactor operating at high pressure. Several different reactor designs useful in this process include; a stirred-tank reactor (batch and/or continuous flow); a plug flow reactor; a static mixer used as a reactor; at least one of the above reactors operating at high pressure; optionally combined with a distillation column running at a lower pressure; and combinations of the above; and/or with a distillation column. The resulting product stream consisting of 1233zd, HCl, HF, and other byproducts is partially condensed to recover HF by phase separation. The recovered HF phase is recycled to the reactor. The HCl is scrubbed from the vapor stream and recovered as an aqueous solution. The remaining organic components including the desired HCFC-1233zd are scrubbed, dried and distilled to meet commercial product specifications.
    • 公开了从HCC-240和HF的反应制备商业规模的1-氯-3,3,3-三氟丙烯(HCFC-1233zd)的方法。 在一个实施方案中,将HCC-240fa和HF加入到在高压下操作的反应器中。 在这个过程中有用的几种不同的反应器设计包括: 搅拌釜反应器(批次和/或连续流动); 活塞流反应器; 用作反应器的静态混合器; 上述反应器中的至少一个在高压下运行; 任选地与在较低压力下运行的蒸馏塔组合; 和上述的组合; 和/或用蒸馏塔。 由1233zd,HCl,HF和其他副产物组成的产物流部分冷凝,通过相分离回收HF。 将回收的HF相再循环到反应器中。 将HCl从蒸汽流中洗涤并作为水溶液回收。 将包含所需HCFC-1233zd的剩余有机组分进行洗涤,干燥和蒸馏以满足商业产品规格。

    • The present invention relates to a hydrofluorinating process which comprises reacting a fluoroolefin with hydrogen fluoride in the liquid phase in the presence of a hydrofluorination catalyst in the reaction zone of a reactor, said reactor comprised of a reactor body having a length to diameter ratio of about 2:1 or greater; a stirred reaction zone containing said hydrofluorination catalyst, which may be prepared in situ, at least one inlet for supplying said hydrogen fluoride and fluoroolefin to the reaction zone and at least one outlet for recovering said fluoroalkane, said stirrer disposed in the reaction zone and comprising a plurality of blades fixedly attached to shaft drivable by a motor, said blades extending from about the bottom of the reaction zone to about the top of the reaction zone and said shaft extending on a longitudinal axis from the bottom of the reactor to the top of the reactor, said stirrer being rotated at a speed sufficient to promote a swirling of the liquid to effect the occurrence of hydrofluorination reaction and minimize overfluorination. The present invention also relates to said hydrofluorination reactor.
