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.

摘要： Processes for the production of chlorinated propenes are provided wherein a dehydrochlorination reaction occurs prior to a first chlorination reaction. The present processes make use of at least one reactor twice, i.e., at least two reactions occur in the same reactor. Cost and time savings are thus provided. Additional savings can be achieved by conducting more than two chlorination reactions, or all chlorination reactions, in one chlorination reactor, and/or by conducting more than two dehydrochlorination reactions, or all dehydrochlorination reactions, within a single dehydrochlorination reactor.

摘要： The present invention provides a method for simplifying manufacture of a mixed alcohol or mixed oxygenate product from synthesis gas. The mixed alcohol or mixed oxygenate product contains ethanol and other oxygenates with two or more carbon atoms per molecule. The method includes stripping a portion of carbon dioxide and inert gases contained in a mixed alcohol synthesis reaction product using a methanol-containing stream, such as one produced as part of the method, as a medium to absorb said carbon dioxide and inert gases and recycling light products and heavy products to one or more of synthesis gas generation, mixed alcohol synthesis and separation of desired mixed alcohol or mixed oxygenate products from other components of a mixed alcohol synthesis stream. The present invention also provides downstream processing of the mixed alcohol or mixed oxygenate product by subjecting the product to a dehydration step in order to convert at least ethanol, preferably at least ethanol and propanol, to their corresponding olefins (e.g. ethylene and propylene).
