Latest Patents

Among his latest patents, two notable inventions stand out. The first is a **method for preparing low migration plasticizer of di-2-ethylhexyl terephthalate**. This innovation outlines a process involving the use of short-chain alcohols (4 to 6 carbon atoms) and long-chain alcohols (9 to 13 carbon atoms) in an esterification reaction with terephthalic acid and 2-ethylhexanol. The process operates at varying temperatures (30° C. to 225° C.) and pressures (80 mbar to 1033 mbar) to create a modified plasticizer that retains desirable properties while reducing migration.

The second is a **method for manufacturing nonylcyclohexanol**. This invention describes a systematic approach where a liquid phase reactant, comprising molten nonylphenol and a catalyst, is introduced into a reactor. The method further incorporates a gas phase reactant (hydrogen) under a pressure of 36.5 to 70 bar, achieved through a unique stirring mechanism that enhances the reaction efficiency. Remarkably, this method yields a conversion rate of nonylcyclohexanol higher than 99.0%, showcasing its effectiveness in chemical production.
