John F Manning is a notable inventor based in Albany, California. He has made significant contributions to the field of polymer chemistry, particularly in the area of olefin polymerization and the purification of maleic anhydride. With a total of two patents to his name, Manning's work has had a considerable impact on industrial processes.
Latest Patents
Manning's latest patents include a solid phosphoric acid catalyzed olefin polymerization process. This innovative method improves the polymerization of C3-C12 olefins, such as propylene, by utilizing a solid phosphoric acid catalyst in conjunction with an alkanol. The catalyst not only facilitates the polymerization but also aids in the decomposition of the alkanol into water and olefin. This process helps maintain a consistent phosphoric acid strength without exposing the catalyst to excess liquid water, thereby enhancing overall polymerization conversions and extending catalyst life.
Another significant patent by Manning is the purification of maleic anhydride. This method involves combining a metal halide with P2O5 or a perborate before the final distillation of crude anhydride. The preferred metal halides for this process include alkaline earth and transition metal halides, particularly magnesium, calcium, and iron chlorides. This purification method is especially beneficial for maleic anhydride produced through butane oxidation, ensuring good color stability.
