Latest Patents

Zhigao Xia holds a patent for a process titled "Process for the hydroformylation of olefinically unsaturated compounds." This patent describes a method for hydroformylating olefinically unsaturated compounds whose products are either insoluble or only sparingly soluble in water. The process involves reacting these compounds at temperatures ranging from 60 to 180 degrees Celsius and pressures between 1 to 35 MPa, using carbon monoxide and hydrogen in a homogeneous phase within a polar organic solvent. The catalyst system utilized in this process includes a rhodium carbonyl compound and a salt of a sulfonated or carboxylated organic monophosphine or polyphosphine, which is soluble in both the polar organic solvent and water. The method concludes with the distillation of the polar organic solvent and the separation of the catalyst system from the distillation residue through water extraction. Zhigao Xia has 1 patent to his name.
