Patent number: 9018127Abstract: A reduced metallic catalyst or pre-activated catalyst is formed by contacting a precursor catalyst or a reduced metallic catalyst with a modifier solution in the presence of a source of hydrogen and heat treating the precursor catalyst or the reduced metallic catalyst at super-atmospheric pressure to obtain the reduced metallic catalyst from the precursor catalyst or the pre-activated catalyst from the reduced metallic catalyst. A method of hydrogenating a hydrogenatable precursor includes providing a reduced metallic catalyst or the pre-activated catalyst prepared with modifier buffer and contacting the reduced metallic catalyst or pre-activated catalyst with the hydrogenatable precursor in the presence of hydrogen and, optionally, in the presence of a modifier solution.Type: GrantFiled: January 8, 2013Date of Patent: April 28, 2015Assignee: BioAmber International S.a.r.l.Inventors: Setrak K.

Publication number: 20150005510Abstract: This invention relates to a process for preparing 2-pyrrolidone (also called 2-pyrrolidinone) and N-methylpyrrolidone (also called N-methylpyrrolidinone) from diammonium succinate in fermentation broth. In the first stage of this invention, renewable carbon resources are utilized to produce diammonium succinate through biological fermentation. In the second stage of this present invention, diammonium succinate is converted into 2-pyrrolidone and N-methylpyrrolidone through a two step reaction. Both the steps of the reaction leading to the production of 2-pyrrolidone and N-methylpyrrolidone are carried out in a solvent phase to prevent the loss of succinimide through hydrolysis.Type: ApplicationFiled: August 31, 2012Publication date: January 1, 2015Applicant: MYRIANT CORPORATIONInventors: Thidarat Tosukhowong, Kirk Roffi, Santosh Raghu More, Robert L.

Publication number: 20100152435Abstract: Processes for oxidation of primary alcohols or aldehydes into the corresponding carboxylic acids are provided herein, including processes for the aerobic catalytic oxidation of a hydroxyl moiety pendant to a cyclic carbohydrate to a carboxylic acid in a manner that preserves the cyclic carbohydrate structure. The oxidation processes may be performed in the absence of a transition metal catalyst, halogenated solvent and a hypochlorite reagent. The processes and compositions with and without a bromide source are provided. A liquid reaction media comprising a carboxylic acid and a catalyst composition may be combined with the reactant alcohol substrate to form a reaction media which can be pressurized at constant volume with an oxygen-containing gas under conditions of temperature and constant pressure within a reaction vessel to selectively oxidize the reactant substrate to form a carboxylic acid product.Type: ApplicationFiled: March 14, 2008Publication date: June 17, 2010Inventors: Jonathan A.

Patent number: 5446003Abstract: An improved technique is provided for the expeditious formation of a supported catalyst suitable for use in a vapor phase chemical reaction wherein the catalyst is provided as discrete particles. The support need not be capable of withstanding a highly elevated temperature, and may simply be paper or any other readily available material. A layer of deformable adhesive (preferably an organic adhesive) is provided as a liquid or paste on the surface of the support. Particles of a preformed activated catalyst are dispersed on the outer surface of the adhesive so that only a minor portion of the surfaces of the particles is embedded therein. Next the adhesive is solidified under appropriate conditions while maintaining the exposure of a major portion of the surfaces of the solid preformed catalytic particles to the atmosphere. Throughout the formation process the catalytic activity of the exposed surfaces of the catalytic particles remains substantially unaltered.Type: GrantFiled: January 12, 1993Date of Patent: August 29, 1995Assignee: Philip Morris IncorporatedInventors: Robert L.
