摘要: Disclosed is a process for the manufacture of 1234yf from 1,1,2,3-tetrachloropropene, abbreviated herein as “TCP,” in three integrated steps: (a) the R-1 hydrofluorination of TCP to form 1233xf in the vapor phase; (b) the R-2 hydrofluorination of 1233xf to form 244bb in either the liquid phase or in the liquid phase followed by the vapor phase; and (c) the R-3 dehydrochlorination of the 244bb in either the liquid or the vapor phase to produce 1234yf; wherein the vapor phase hydrofluorination of TCP in step (a) is carried out at a higher pressure than the liquid phase hydrofluorination of 1233xf; andwherein the HC1 generated during these steps is scrubbed with water to form an acid solution and the organic components are scrubbed with a caustic solution and then dried before further processing.

摘要: Disclosed is a process and apparatus for the catalytic hydrogenation of fluoro-olefins to fluorocarbons where the reaction is carried out in a multi-tube shell and tube reactor. Reactions involving hydrogenation of fluoro-olefins are typically exothermic. In commercial processes where a fluoro-olefin CnH2n-xFx to CnH2n-x2Fx is hydrogenated (e.g., hexafluoropropylene to 236ea, 1225ye to 245eb, and the like), inadequate management or control of heat removal may induce excess hydrogenation, decomposition and hot spots resulting in reduced yields and potential safety issues. In the hydrogenation of fluoro-olefins, it is therefore necessary to control the reaction temperature as precisely as practical to overcome challenges associated with heat management and safety.

摘要: The present invention is directed to a combination reactor system for exothermic reactions comprising a trickle-bed reactor and a shell-and-tube reactor. This combination allows the system to efficiently remove heat while also providing the ability to control both the temperature and/or reaction progression. The trickle-bed reactor removes heat efficiently from the system by utilizing latent heat and does not require the use of a cooling or heating medium. The shell-and-tube reactor is used to further progress the reaction and provides a heat exchanger in order to introduce fluid at the desired temperature in the shell-and-tube reactor. Also, additional reactant or reactants and/or other fluids may be introduced to the shell-and-tube section of the reactor under controlled temperature conditions.

摘要: A multi-stage, multi-tube, shell-and-tube reactor which contains reaction zones and interstage temperature control (cooling/heating) zones in series. The reactor has at least two types of zones which both contribute to removing or supplying heat to the system depending on the system's need. The reactor will have a group of reaction zones which contain tubes packed with catalyst to progress the reaction and remove or supply heat simultaneously. There are also a number of interstage temperature control (cooling/heating) zones which are designed to supply or remove heat to or from the system. The positioning, number, and design of the zones will depend on the amount of temperature control desired and exothermic or endothermic nature of the processes to be conducted in the reactor.
