Abstract:
A reactor apparatus is provided having a reaction chamber; a compartmentalizing apparatus including a plurality of compartments, each compartment being open at a top end and bottom end, the compartmentalizing apparatus being disposed within the reaction chamber; and an inlet disposed at an area of the reactor and in fluid communication between the reaction chamber and a feed source. Also provided is a reactor apparatus having an assembly having a reaction chamber; at least one agitator assembly configured to generate mixing within the reaction chamber, the agitator assembly including: a shaft partially lined or coated with a fluoropolymer or other non-metallic corrosion-resistant material, and an impeller lined or coated with the fluoropolymer or other non-metallic corrosion-resistant material; and an inlet disposed at an area of the reactor and in fluid communication between the reaction chamber and a feed source. The provided reactor apparatus can be utilized in hydrofluorination processes.

Abstract:
The invention relates to a process to produce HCFC-244bb from HCFO-1233xf wherein, in one embodiment, one or more co-feed species having a normal boiling point of between about -80°C to about 0°C, such as HFC-245cb, is added to the reaction at a pressure of at least about 100 psig; and in another embodiment it is added to maintain a mole ratio of HFC-245cb to HCFO- 1233xf of between about 0.005:1 to about 1:1. The HFC-245cb may be added as recycled by-product of the reaction and/or added as fresh feed. The HFC-245cb provides elevated pressures to the reaction thereby facilitating reactor operation, mixing and HCFC-244bb product removal. Other co-feed species are also disclosed.
Abstract:
La invención se refiere a un proceso para producir HCFC-244bb de HCFO-1233xf en donde, en una modalidad, una o más especies de co-alimentación que tienen un punto de ebullición normal de entre aproximadamente -80 °C a aproximadamente O °C, tales como HFC -245cb, se añade a la reacción a una presión de al menos aproximadamente 0.68 MPa; y en otra modalidad se añade a mantener una relación en moles de HFC-245cb a HCFO-1233xf de entre aproximadamente 0.005: 1 a aproximadamente 1: 1. El HFC-245cb se puede añadir como reciclado de subproductos de la reacción y/o añadido a la alimentación fresca. El HFC-245cb ofrece presiones elevadas a la reacción facilitando de este modo el funcionamiento del reactor, el mezclado y el retiro del producto HCFC-244bb. También se describen otras especies co-alimentadas.
