It also makes very stable oil-in-water emulsions, and adds a slippery feel and lubricity to shaving and skin cleaning products.Type: ApplicationFiled: April 11, 2008Publication date: June 17, 2010Applicant: ALZO INTERNATIONAL, INC.Inventors: Albert A.

Patent number: 7622597Abstract: Method of preparation of maleimides by thermal cyclization of maleamic acids in the presence of a catalyst consists in that reaction of a substituted maleic anhydride with a primary amine is performed in an organic solvent in the presence of betaine at a temperature of 100 to 180° C., at a ratio of the primary amine to the substituted maleic anhydride of 0.6:1.6. Maleimides, obtained in this way, are further purified by extraction, and finally, they are crystallized. As a catalyst, there may be also used betaine in a mixture with inorganic and organic acids, or betaine may be deposited on a solid carrier, or possibly, betaine may be deposited on a carrier in combination with inorganic acids.Type: GrantFiled: December 15, 2005Date of Patent: November 24, 2009Assignee: Vucht A.S.Inventors: Zsolt Vegh, Jozef Balko

Publication number: 20090264672Abstract: Described are methods of making organic compounds by metathesis chemistry. The methods of the invention are particularly useful for making industrially-important organic compounds beginning with starting compositions derived from renewable feedstocks, such as natural oils. The methods make use of a cross-metathesis step with an olefin compound to produce functionalized alkene intermediates having a pre-determined double bond position. Once isolated, the functionalized alkene intermediate can be self-metathesized or cross-metathesized (e.g., with a second functionalized alkene) to produce the desired organic compound or a precursor thereto. The method may be used to make bifunctional organic compounds, such as diacids, diesters, dicarboxylate salts, acid/esters, acid/amines, acid/alcohols, acid/aldehydes, acid/ketones, acid/halides, acid/nitriles, ester/amines, ester/alcohols, ester/aldehydes, ester/ketones, ester/halides, ester/nitriles, and the like.Type: ApplicationFiled: April 10, 2009Publication date: October 22, 2009Applicant: Elevance Renewable Sciences, Inc.Inventors: Timothy W.
