- NOVEL PRODUCTS IN THE CO2-LASER INDUCED REACTION OF TRICHLOROETHYLENE
-
Previous report on the thermal or CO2-laser induced decomposition of trichloroethylene have identified only one condensable product, hexachlorobenzene (in addition to HCl and mono- and dichloroacetylene).We have found that trichloroethylene vapor exposed to cw irradiation on the P(24) line of the (001-100) band of the CO2 laser at incident power levels from 8-17 W procedures numerous products, of which the 13 major ones have been identified using IR, GC/MS, GC/FTIR, and NMR methods.All of these products have 4, 6, or 8 carbons, are highly unsaturated, and are completely chlorinated or contain a single hydrogen.C4HCl5 and C6Cl6 isomers (three of each) account for ca. 55percent to 85percent of total products (based on peak area in the total ion chromatograms in GC/MS runs), depending on reaction conditions.In addition to characterizing the products, we discuss the dependence of the product distribution on laser power, irradiation time, and cell geometry, and we outline a possible mechanism.

- POLYHALOGENIERTE ETHANE IN DER KINNEAR-PERREN-REAKTION
-
Fluorinated ethanes (Refrigerants) were caused to react with AlCl3 and PCl3 of CH3PCl2 resp.Complete defluorination led to polychlorinated phosphonicdichlorides and phosphinicchlorides.Reactions with AlBr3 and PB3 produced halogenated ethyldibromophosphines.
