摘要： An improved method of producing methyl alcohol (methanol) from methane is provided using two reaction steps operated in tandem. In the first reaction step two chemical reactions occur simultaneously: a) perchloroethylene (CCl2CCl2) is oxychlorinated with hydrogen chloride and oxygen to obtain hexachlorethane (CCl3CCl3) and water, and b) methyl chloride (CH3Cl) is hydrolyzed with water to give methyl alcohol and hydrogen chloride. In the second reaction step methane is chlorinated with hexachlorethane to produce methyl chloride, hydrogen chloride and perchloroethylene. By recycling the methyl chloride, hydrogen chloride, and regenerated perchloroethylene produced in the second step to the first step the process can be operated in a balanced mode whereby the internal consumption of hydrogen chloride is equal to its formation.

摘要： A process is provided for the chlorination of methane using hydrogen chloride as a source of chlorine. The process includes reaction steps operated in tandem in separate zones first comprising the reaction of perchloroethylene with hydrogen chloride and oxygen in the presence of an oxychlorination catalyst to give hexachloroethane and water, and second comprising the vapor phase reaction of hexachloroethane with methane feedstock to produce chlorinated methane, perchloroethylene and hydrogen chloride.

摘要： A process is provided for the production of allyl chloride from three carbon atom hydrocarbons (propane and/or propylene) using hydrogen chloride or hydrogen chloride/chlorine mixtures as the chlorinating agent. The process includes reaction steps operated in tandem in separate zones first comprising the reaction of perchloroethylene with hydrogen chloride and oxygen in the presence of an oxychlorination catalyst to give hexachloroethane and water, second comprising the vapor phase reaction of hexachloroethane with propane/propylene feedstock to produce allyl chloride, perchloroethylene, and hydrogen chloride, and third isolating the products of the second step and repeating the first step using as starting materials the thus isolated perchloroethylene and hydrogen chloride.
