PROCESSES FOR PREPARING PENTACHLOROPROPANE AND TETRACHLOROPROPENE FROM DICHLOROPROPENE
A processes for preparing 1,1,2,3-tetrachloropropene, 2,3,3,3-tetrachloropropene, or a mixture thereof from 1,3-dichloropropene. The process may include a two successive chlorination and dehydrochlorination reactions. In a first chlorination reaction 1,3-dichloropropene is reacted with a chlorination agent to form a first chlorination reaction product including 1,1,2,3-tetrachloropropane. This first chlorination reaction product is reacted with a dehydrochlorination reagent in a first dehydrochlorination reaction to form a first dehydrochlorination reaction product including a trichloropropene. The trichloropropene containing reaction product is reacted with a chlorination agent in a second chlorination reaction to form a second chlorination reaction product including at least one of 1,1,1,2,3-pentachloropropane or 1,1,2,2,3-pentachloropropane. This reaction product is reacted with a dehydrochlorination reagent in a second dehydrochlorination reaction to form a second dehydrochlorination reaction product having 1,1,2,3-tetrachloropropene or a 2,3,3,3-tetrachloropropene.

PROCESS FOR THE PRODUCTION OF CHLORINATED PROPANES AND/OR PROPENES
Processes for the production of chlorinated propanes and/or propenes are provided. The present processes make use of methylacetylene, a by-product in the production of ethylene and/or propylene, as a low cost starting material, alone or in combination with propadiene, propene and/or propane. In the latter embodiments, the processes may also be utilized to provide a substantially pure stream of propane.

PROCESS FOR THE PRODUCTION OF CHLORINATED PROPANES AND/OR PROPENES
Processes for the production of chlorinated propenes are provided wherein the feedstream comprises 1,2-dichlropropane. 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.

Preparation of (Z)-1,2-dichloroalkenes from terminal alkynes
(Z)-1,2-Dihaloalkenes are thermodynamically disfavoured of the two stereoisomers. This paper reports the synthesis of some (Z)-1,2-dichloroalkene analogues from mucochloric acid. A more versatile approach involved the chloroboration of terminal alkynes to yield corresponding (Z)-chloroboronic acid as a first step. Treatment of the organoboronic acid with potassium hydrogen difluoride followed by tetrabutylammonium trichloride gave (Z)-1,2- dichloroalkenes in moderate to good yields in a stereospecific manner.

SYNTHESIS AND PROPERTIES OF TRIETHYLBENZYLAMMONIUM ALKOXIDES. REACTIVITY IN ELIMINATION AND NUCLEOPHILIC SUBSTITUTION REACTIONS
Triethylbenzylammonium alkoxides exhibit high reactivity during the elimination of hydrogen chloride from polychloroalkanes and can also be used in the synthesis of ethers from halogenoalkanes.Quaternary ammonium salts do not form tetraalkylammonium or trialkylbenzylammonium alkoxides under the influence of a concentrated aqueous solution of sodium hydroxide in the presence of alcohols.
