实验步骤: A mixture consisting of 2.2 gm of methyl 2-[4-(4-chlorophenoxy-methyl)-phenoxy]-propionate, 2.4 gm of 2-(2,4,5-trichloro-phenoxy)-ethanol and 0.03 gm of sodium was heated at about 120°-150° C. and a pressure of 150 mm Hg for four hours. After cooling, the reaction mixture was briefly boiled with acetone, the cooled solution was filtered, and the solvent was removed from the filtrate in vacuo. The residue was recrystallized from ethanol/water, yielding 1.3 gm (36% of theory) of the compound of the formula ##STR19## which had a melting point of 83° C. was heated at about 120°-150° C. After cooling the cooled solution was filtered the solvent was removed from the filtrate in vacuo The residue was recrystallized from ethanol/water yielding 1.3 gm (36% of theory) of the compound of the formula ##STR19## which

实验步骤: The overhead stream comprising 1,2,3-trichloropropane, TCPE, tetrachloropropanes, 1,1,2,2,3-pentachloropropane, 1,1,1,2,3-pentachloropropane, and 1,1,1,2,2-pentachloropropane is then provided to a reactor where it is dehydrochlorinated to provide dichloropropenes, trichloropropenes, 2,3,3,3-tetrachloropropene, and 1,1,2,3-tetrachloropropene. More specifically, dehydrochlorination reactor may typically be a batch or a continuous stirred tank reactor. The mixing can be done, e.g., by mechanical or jet mixing of feed streams. Those of ordinary skill in the art are readily able to determine the appropriate conditions at which to run a dehydrochlorination reactor in order to conduct the aforementioned dehydrochlorination. is then provided to a reactor where it

实验步骤: In the present process, dichloropropane is converted to a chlorinated alkene, e.g., TCPE, using a series of consecutive chlorination and dehydrochlorination steps. In one exemplary embodiment, PDC is fed to a liquid phase chlorination reactor, e.g., such as a batch or continuous stirred tank autoclave reactor with an internal cooling coil. A shell and multitube exchanger operating in plug flow, followed by vapor liquid disengagement tank or vessel can also be used. Suitable reaction conditions include, e.g., a temperature of from 30° C. to 150° C., a pressure of from 100 kPa to 2000 kPa. The reaction is carried out in the presence of one or more regioselective catalysts that provide a regioselectivity to, e.g., 1,1,2-trichloropropane of at least 5:1 over other trichloropropane isomers. Suitable reaction conditions of from 30° C. to 150° C.
