Usage

General Description

2-Chloro-1,3-butadiene, also known as chloroprene, is a synthetic organic compound that is primarily used in the production of polymers such as neoprene. It is a colorless liquid with a chloroform-like odor and is classified as a possible human carcinogen. The principal use of 2-Chloro-1,3-butadiene is in the manufacturing of neoprene, a type of synthetic rubber that is commonly used for wetsuits, electrical insulation, and gaskets. It is also used in the production of adhesives, coatings, and sealants. However, exposure to 2-Chloro-1,3-butadiene can pose health risks, with inhalation and skin contact being the main routes of exposure. Therefore, proper safety measures should be taken when handling this chemical.

Strontium chloride modified Nieuwland catalyst in the dimerization of acetylene to monovinylacetylene

SrCl2 was used as a co-catalyst of CuCl in Nieuwland catalyst and CuCl as the main catalyst, NH4Cl as the solubilizer, water as the solvent and a certain amount of hydrochloric acid, thereby forming Sr-Cu bimetallic cooperative catalysis reaction systems for C2H2 dimerization. Under the optimum condition, the acetylene conversion is 13 % and monovinylacetylene selectivity can reach to 94 %.

Thermal ring opening of 1,1-dibromo and 1-bromo-2- chloromethylcyclopropanes: Observation of a formal debromochlorination

When the title compounds are thermolyzed in the gas phase under vacuum or in hot quinoline, several products are formed. A predominant product in all cases is a chlorine-free buta-1,3-diene which has been formed by formal debromochlorination, a reaction n

Gas phase surface-catalyzed HCl addition to vinylacetylene: motion along a catalytic surface. Experiment and theory

Gaseous mixtures of HCl and vinylacetylene were permitted to react in Pyrex IR cells (NaCl windows). Gaseous 4-chloro-1,2-butadiene and 2-chloro-1,3-butadiene (chloroprene) were the major products. Kinetic data (FTIR) generated a rate expression in concert with surface catalysis. Computational studies involving surface associated water provide a view that accounts for the experimentally determined orders and a bifurcated pathway producing both products. The results are in accord with wall-adsorbed reactant(s) as well as previously reported computational studies on the reactants.
