Abstract: This invention provides an attrition resistant catalyst composition and method for producing such composition. The catalyst is comprised of an acidic zeolite, rho or chabazite, and a particulate binder, kaolin, bentonite, alpha-alumina, or titania, which can be optionally modified by treatment with a compound containing Si, Al, P or B. This invention further provides a process for producing methylamines, preferably dimethylamine, comprising reacting methanol and/or dimethyl ether and ammonia in the presence of a catalytic amount of an attrition resistant catalyst of the invention.

Abstract: Mixtures of CClF.sub.2 CF.sub.3 (CFC-115) and CHF.sub.2 CF.sub.3 (HFC-125) can be substantially separated by using carbon nanotubes as a sorbent for CClF.sub.2 CF.sub.3. A process is described for treating a starting mixture of CHF.sub.2 CF.sub.3 and CClF.sub.2 CF.sub.3 to provide a product wherein the mole ratio of CHF.sub.2 CF.sub.3 to CClF.sub.2 CF.sub.3 is increased relative to the mole ratio of CHF.sub.2 CF.sub.3 to CClF.sub.2 CF.sub.3 in the starting mixture; and another process (involving desorbing sorbed CClF.sub.2 CF.sub.3) is disclosed for treating a starting mixture of CClF.sub.2 CF.sub.3 and CHF.sub.2 CF.sub.3 to provide a product mixture wherein the mole ratio of CClF.sub.2 CF.sub.3 to CHF.sub.2 CF.sub.3 is increased relative to the mole ratio of CClF.sub.2 CF.sub.3 to CHF.sub.2 CF.sub.3 in the starting mixture. The process for producing a CHF.sub.2 CF.sub.3 -enriched product and the process for producing a CClF.sub.2 CF.sub.3 -enriched product may be integrated into an overall process (e.g., a thermal swing cycle process) where both of said products are provided. Production of high purity HFC-125 is disclosed.

Abstract translation: 通过使用碳纳米管作为CClF 2 CF 3的吸附剂，CClF 2 CF 3（CFC-115）和CHF 2 CF 3（HFC-125）的混合物可以基本上分离。 描述了一种处理CHF 2 CF 3和CClF 2 CF 3起始混合物以提供其中CHF2CF3与C​​ClF2CF3的摩尔比相对于起始混合物中CHF 2 CF 3与CClF 2 CF 3的摩尔比增加的产物的方法; 公开了另一种方法（包括解吸吸附的CClF 2 CF 3），用于处理CClF 2 CF 3和CHF 2 CF 3的起始混合物以提供其中CClF 2 CF 3与CHF 2 CF 3的摩尔比相对于起始混合物中CClF 2 CF 3与CHF 2 CF 3的摩尔比增加的产物混合物。 富含CHF2CF3的产物的制备方法和富含CClF2CF3的产物的制备方法可以整合到其中提供两种所述产物的整个方法（例如，热循环循环过程）中。 公开了高纯度HFC-125的生产。
