His innovative work has led to the creation of a unique preparation method that simplifies the production process of polyethers.

Latest Patents

Hongjun Gao holds a patent for a high-molecular weight allyl alcohol polyoxyethylene polyoxypropylene ether and its preparation method. This invention involves a process where an allyl alcohol raw material and a supported catalyst, Rb-NHPA, are introduced into a high-pressure reaction kettle. The mixture is heated after being replaced with nitrogen gas. Once the internal temperature reaches the desired reaction temperature, a mixture of ethylene oxide (EO) and propylene oxide (PO) is continuously fed into the kettle for reaction. After the reaction, acetic acid is added dropwise to neutralize the crude product. This method omits the refining process of polyether, greatly simplifies the workflow, and effectively reduces processing time. Additionally, the supported catalyst Rb-NHP can be recycled, enhancing the sustainability of the process.
