Title: Joseph F. Englert, Jr.: A Pioneer in Chloroprene Production
Introduction
Joseph F. Englert, Jr., based in La Place, Louisiana, is an innovator whose contributions to the chemical industry have led to significant advancements in the production of chloroprene. With two patents to his name, Englert has played a crucial role in developing processes that enhance the efficiency and effectiveness of chloroprene manufacturing, which is vital for producing synthetic elastomers used in various industrial applications.
Latest Patents
Englert’s recent inventions showcase innovative methods to improve chloroprene production. His patents include:
1. **Removal of catalyst from chloroprene by treatment with oxy acid**: This invention involves the removal of a quaternary ammonium phase transfer catalyst from the dehydrochlorination product of 3,4-dichlorobutene-1. The process utilizes an oxy acid that combines with the catalyst, forming a separate phase, thereby enhancing the efficiency of the overall production process.
2. **Process for the manufacture of chloroprene**: This improved process focuses on the catalytic dehydrochlorination of 3,4-dichlorobutene-1 using aqueous alkali. In this method, the effluent from the dehydrochlorination reactor undergoes phase separation. The organic phase is then steam-stripped at low temperatures (below 80°C) to recover chloroprene. The design allows for recycling most of the catalyst back into the reaction while managing make-up catalyst needs efficiently.
