    摘要: Hybrid polyester-polyether polyols are prepared by polymerizing an alkylene oxide in the presence of a carboxylate initiator. The polymerization is catalyzed with a mixture of double metal cyanide catalyst complex and certain magnesium, group 3-group 15 metal or lanthanide series metal compounds. The presence of the magnesium, Group 3-Group 15 metal or lanthanide series metal (MG3-15LA) compound makes for consistently rapid activation of the double metal cyanide catalyst complex, even in the presence of carboxylate initiator compounds. This leads to greater productivity and reduced manufacturing costs due to shorter cycle times and less waste of raw materials due to the failure of the catalyst to become activated. Once the catalyst is activated, it often polymerizes the alkylene oxide at a faster rate that the DMC catalyst by itself.

    摘要: Processes for the production of chlorinated propenes are provided. The present processes make use of 1,2-dichloropropane, a by-product in the production of chlorohydrin, as a low cost starting material, alone or in combination with 1,2,3-trichloropropane. The present processes can also generate anhydrous HCl as a byproduct that can be removed from the process and used as a feedstock for other processes, providing further time and cost savings. Finally, the processes are advantageously conducted in the liquid phase, thereby presenting additional savings as compared to conventional, gas phase processes.

    摘要: Processes for the production of chlorinated propenes are provided. The present processes make use of a feedstream comprising 1,2-dichloropropane, a by-product in the production of chlorohydrin, as a low cost starting material, alone or in combination with 1,2,3-trichloropropane. Selectivity of the process is enhanced over conventional processes employing successive chlorinations and/or dehydrochlorinations, by conducting at least one chlorination in the presence of an ionic chlorination catalyst. The present processes may also generate anhydrous HCl as a byproduct that can be removed from the process and used as a feedstock for other processes, providing further time and cost savings.

    摘要: Processes for the production of chlorinated propenes are provided. The present processes make use of a feedstock comprising 1,2,3-trichloropropane and chlorinates the 1,1,2,3-tetrachloropropane generated by the process prior to a dehydrochlorination step. Production of the less desirable pentachloropropane isomer, 1,1,2,3,3-pentachloropropane, is thus minimized. The present processes provide better reaction yield as compared to conventional processes that require dehydrochlorination of 1,1,2,3-tetrachloropropane prior to chlorinating the same. The present process can also generate anhydrous HCl as a byproduct that can be removed from the process and used as a feedstock for other processes, while limiting the production of waste water, thus providing further time and cost savings.
