Latest Patents

Cohen's latest patents include innovative processes for the production of bromostyrene, dibromostyrene, and alkyl bromides. One of her notable inventions involves a method for the simultaneous production of bromostyrene or dibromostyrene and an alkyl bromide. This process entails reacting bromoethyl bromobenzene or bromoethyl dibromobenzene with an alkanol at elevated temperatures. Specifically, when only these reactants are used, the temperature ranges from 400°C to 550°C. However, when the reaction occurs in the presence of a free radical source, the temperature can be lowered to around 300°C. Another significant patent focuses on the production of mono-, di-, and/or tribromostyrene. This process involves reacting β-bromomethyl-mono-, di-, and/or tribromobenzene at temperatures between 280°C to 470°C, also in the presence of a free radical source and either a lower alkanol or water.
