Latest Patents

Holler's patent centers on a novel method for the production of 1,2-dichloroethane, a vital chemical compound used in various applications. His process involves subjecting ethylene to an oxychlorination reaction with hydrogen chloride and a gas containing molecular oxygen. This reaction occurs in the gas phase at elevated temperatures and utilizes a fluidized bed copper-II-chloride catalyst on a carrier. The method innovatively includes a two-stage condensation process that cools the reaction gases under pressure, allowing for the efficient removal of condensed 1,2-dichloroethane and water while recycling the majority of unreacted starting gas.

The process further refines the reaction by allowing the remaining gases to undergo a third condensation stage, cooling down to 5 to 18 degrees Celsius. This ensures that the recycle gas maintains an appropriate concentration of 1,2-dichloroethane, which is directly mixed with pure oxygen to replenish consumed oxygen levels.
