Latest Patents
Qingmei Wan holds a patent for a high-molecular weight allyl alcohol polyoxyethylene polyoxypropylene ether and its preparation method. This patent describes 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 simplifies the process flow and significantly reduces preparation time, while also allowing for the recycling of the supported catalyst.
