Influence of Supporting Silica Gel on the Catalytic Activity of B-18 Crown Ether-KCl Complex for the Selective Dehydrochlorination of 1,1,2-Trichloroethane

Catalytic dehydrochlorination of 1,1,2-trichloroethane into 1,1-dichloroethylene proceeded selectively around 200 deg C over dibenzo-18-crown-6-KCl complex supported on silica gels.The reaction rate depended very much on the kinds of silica gel and impregnation levels of the complex, suggesting some roles of surface hydroxyl groups in this catalysis.

Hydrogen-Atom-Induced Decomposition of Trichloroethylene at High Temperatures

Mechanisms and rate constants for hydrogen atom attack on trichloroethylene have been determined in single-pulse shock tube experiments near 1050 K.Products from all the decomposition channels have been observed.The predominant process is the displacement of the chlorine at the least substituted site.The following rate expressions have been determined: k(H* + HClC=CCl2 -> H2C=CCl2 + Cl*) = 6 x 1E13 exp(-2439/T) cm3 mol-1 s-1; k(H* + HClC=CCl2 -> HClC=CClH (cis + trans) + Cl*) = 3.7 x 1E13 exp(-3946/T) cm3 mol-1 s-1; k(H* + HClC=CCl2 -> *HC=CCl2 or HClC=CCl* + HCl) = 3.8 x 1E14 exp(-6686/T) cm3 mol-1 s-1.An upper limit for the rate constant of the abstraction process H* + HClC=CCl2 -> *ClC=CCl2 + H2 is 6.5 x 1E10 cm3 mol-1 s-1 at 1050 K.Rate constants for chlorine attack on H2 at these temperatures are a factor of 13 smaller than those on mesitylene.The results are compared with those for hydrogen atom reactions with other unsaturated compounds.Some implications regarding the incineration of chlorinated organics will be discussed.

A nonspectroscopic method to determine the photolytic decomposition pathways of 3-chloro-3-alkyldiazirine: Carbene, diazo and rearrangement in excited state

C60 acts as a mechanistic probe for the formation of carbene, diazo compound, and for the rearranged product via the excited state in the photolysis of 3-chloro-3-isopropyldiazirine and 3-chloro-3-chloromethyldiazirine. The carbene adds to C60 to form methanofullerene, whereas the diazo compound adds to C60 to form fulleroid. The olefin product arises as a result of the rearrangement in the excited state.

Shelf-Stable (E)- A nd (Z)-Vinyl-λ3-chlorane: A Stereospecific Hyper-vinylating Agent

We report the first stereoselective synthesis of stable (E)- A nd (Z)-β-chlorovinyl-λ3-chlorane via direct mesitylation of 1,2-dichloroethylene with mesityldiazonium tetrakis(pentafluorophenyl)borate under mild reaction conditions. The structure of the (E)-vinyl-λ3-chlorane was established by single-crystal X-ray analysis. Because of the enormously high leaving group ability of the aryl-λ3-chloranyl group, vinyl-λ3-chloranes undergo not only SNVσ-type reaction with extremely weak nucleophiles such as perfluoroalkanesulfonate, iodobenzene, and aromatic hydrocarbons but also coupling with phenylcopper(I) species.

Nitrogen-Doped Carbon-Assisted One-pot Tandem Reaction for Vinyl Chloride Production via Ethylene Oxychlorination

A bifunctional catalyst comprising CuCl2/Al2O3 and nitrogen-doped carbon was developed for an efficient one-pot ethylene oxychlorination process to produce vinyl chloride monomer (VCM) up to 76 % yield at 250 °C and under ambient pressure, which is higher than the conventional industrial two-step process (≈50 %) in a single pass. In the second bed, active sites containing N-functional groups on the metal-free N-doped carbon catalyzed both ethylene oxychlorination and ethylene dichloride (EDC) dehydrochlorination under the mild conditions. Benefitting from the bifunctionality of the N-doped carbon, VCM formation was intensified by the surface Cl*-looping of EDC dehydrochlorination and ethylene oxychlorination. Both reactions were enhanced by in situ consumption of surface Cl* by oxychlorination, in which Cl* was generated by EDC dehydrochlorination. This work offers a promising alternative pathway to VCM production via ethylene oxychlorination at mild conditions through a single pass reactor.

An acetylene and methylene chloride coupling reaction for preparing vinyl chloride production dichloroethylene and 1, 1, 2-trichloroethane method of

The invention relates to a method for preparing vinyl chloride and coproducing dichloroethylene and 1,1,2-trichloroethane by acetylene-dichloromethane coupled reaction, which is characterized by comprising the following steps: mixing acetylene and dichloromethane, and simultaneously carrying out dichloromethane coupled reaction and acetylene hydrochlorination on the acetylene and dichloromethane in a catalyst-filled reactor under the action of the catalyst, wherein the mole ratio of the acetylene to the dichloromethane is 0.5-2.5, the reaction temperature is 200-400 DEG C, the volumetric space velocity of the acetylene-dichloromethane gas mixture is 10-500 h, and the dichloromethane coupled reaction generates dichloroethylene, 1,1,2-trichloroethane and chlorine hydride; and further carrying out acetylene hydrochlorination on the generated chlorine hydride and acetylene to generate vinyl chloride. The method can simultaneously coproduce the dichloroethylene, 1,1,2-trichloroethane and other high-added-value products while producing vinyl chloride, and the process is more economical and has wider industrialization prospects.

Highly efficient Mg(OH)Cl/SiO2 catalysts for selective dehydrochlorination of 1,1,2-trichloroethane

A series of Mg catalysts supported on SiO2 were prepared by an incipient wetness impregnation method and tested for gas phase dehydrochlorination of 1,1,2-trichloroethane. It was found that these catalysts were very active and selective for the reaction. The catalytic performance depended on the Mg loading rather than the Mg precursors as the catalysts using Mg(NO3)2·6H2O and MgCl2·6H2O as the precursors showed the similar performance. A catalyst containing 10 wt.% of Mg showed the best performance with a steady state TCE conversion of 92% and cis-dichloroethene selectivity of 91%. Moreover, characterizations of the catalysts revealed the formation of Cl-containing Mg species on the surface during the reaction. The analyses of the compositions of the stable catalysts under working conditions indicated a Cl/Mg ratio of 1, suggesting that Mg(OH)Cl could be the active sites for the reaction.
