标题:Method for synthesis of anhydrothrombin
发明人：SUZUKI TOYOAKI; HOSOKAWA KAZUYA; NAGATA MASANORI
权利人:FUJIMORI KOGYO CO
摘要:A method for a synthesis of anhydrothrombin is provided which features a short process, an easy procedure, and high yields. n The method comprises n (A) a step of causing an active serine residue site of thrombin to react with an inhibitor, n (B) a step of performing an alkali treatment at a pH of not less than 11, and n (C) a step of performing an operation of recovery, and carries out these steps sequentially in the order mentioned, and is characterized by causing at least the step of performing the operation of recovery to proceed in the presence of at least one compound selected from the group consisting of polyhydric alcohols and saccharides, and a salt or an amphoteric electrolyte.

权利人:STANDARD OIL CO OHIO
摘要:A process for producing an ester is disclosed comprising contacting a gaseous reactant containing at least one organic hydroxy compound and a mixture of carbon monoxide and hydrogen with an ester synthesis catalyst of the formula MaAbRuCucNzOx wherein M is selected from the group consisting of Ce, Cr, Fe, Mn and mixtures thereof, A is an alkali metal, alkaline earth metal or mixture thereof, a is from 0 to about 1, b is from 0.002 to about 10, c is from 0.2 to about 20, z is from 0 to about 196 by weight, x is the number of oxygens needed to fulfill the valence requirements of the other elements. The organic hydroxy compound can be provided separately or formed by contacting a mixture of carbon monoxide and hydrogen with an alcohol synthesis catalyst at an elevated temperature and pressure. The alcohol synthesis catalyst and ester synthesis catalyst can be in tandem or mixed.

标 题:Synthesis of environmentally degradable alkyl polyesters
发明人：PARK KINAM; GARNER JOHN SOLOMON
权利人:AKINA INC
摘要:A solid crosslinked polyester composition that is environmentally degradable in less than about 180 days. The crosslinked polyester can be the polyesterification reaction product between one or more multi-hydroxylic alcohols, one or more hydroxy acids, and one or more multi-carboxylic acid compounds. Alternately, the crosslinked polyester can be the polyesterification reaction product of one or more multi-hydroxylic alcohols, one or more hydroxy acids, one or more multi-carboxylic acid compounds, and a cyclic ester. Provided, however that if the one or more hydroxy acids has only one carboxyl group, it has two or more hydroxyl groups, and if the one or more hydroxy acids has only one hydroxyl group, it has two or more carboxyl groups.

权利人:HUNTSMAN PETROCHEMICAL LLC
摘要:The present disclosure provides a process for the co-preparation of a polyetheramine and an alkylene amine mixture by aminating a liquid polyol initiator mixture comprising an alkoxylated alcohol and a solid high melting polyol. The polyetheramine and alkylene amine mixture may be used in a variety of applications, such as a curing agent for epoxy resin formulations or as a raw material in the synthesis of polyurea.

标 题:Synthesis of modified epoxy resins for cathodic electrodeposition with catalyst deactivation and diol modification
发明人：REUTER HARDY; JOUCK WALTER; OTT GUENTHER
权利人:BASF LACKE & FARBEN
摘要:Epoxy resins for preparing water-dispersible binders for cathodic electrodeposition coating materials, the epoxy resin being preparable by reacting a) polyepoxides having at least one glycidyl group per molecule b) and, optionally, up to 60% by weight, based on the overall epoxy resin reaction product, of aliphatic and/or alicyclic hydroxy compounds having preferably two or on average less than two hydroxyl groups per molecule and a molecular weight of less than 9000 g/mol, c) in the presence of a catalyst consisting of neutral metal salts, such as alkali metal salts and alkaline earth metal salts, zinc salts and nickel salts of tetrafluoroboric, tetrachloroboric, hexafluoro- antimonic,hexachloroantimonic,hexafluorophosphoric, perchlorate and periodic acid, and d) adding a deactivating agent which prevents the epoxy groups reacting further or effectively reduces the rate of such reaction as soon as the phenolic hydroxyl groups have already substantially reacted and at least 0.6% by weight of epoxy groups are still present, based on the overall weight of the epoxy resin reaction product.\\!
