Latest Patents

One of his latest patents is a process for producing an unsaturated carboxylic acid from an alkane. This innovative one-step vapor phase oxidation process allows for the production of unsaturated carboxylic acids, such as acrylic acid or methacrylic acid, from alkanes like propane or isobutane. The method utilizes a mixed metal oxide catalyst and maintains an excess of alkane relative to oxygen, allowing for the recycling of unreacted alkane and byproduct alkene back to the reaction zone without separation. This process significantly improves the overall yield and productivity of the unsaturated carboxylic acid.

Another significant patent involves mixed metal oxide catalysts for the production of unsaturated aldehydes from olefins. This catalyst facilitates the gas phase catalytic oxidation of olefins, such as isobutylene, to produce unsaturated aldehydes like methacrolein. The catalyst composition includes oxides of molybdenum, bismuth, iron, and cesium, with specific ratios that optimize its effectiveness.
