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:AIR PROD & CHEM
摘要:The present invention is directed to active compositions, such as adsorbents and catalysts, which comprise cuprous compounds dispersed on amorphous oxide or carbon macroporous supports. The compositions are prepared by impregnating cupric compounds on pretreated supports with the aid of an aqueous solution of an ammonium salt of a di- or polycarboxylic acid dispersant, such as ammonium citrate, followed by activation of the cupric compound or reduction of the cupric compound to the corresponding cuprous compound. Methods of synthesis and processes utilizing the compositions are also disclosed.

摘要:The present invention is directed to a process for adsorptive separation of carbon monoxide or olefins from gas mixtures using adsorbents, which comprise cuprous compounds dispersed on amorphous oxide or carbon macroporous supports. The compositions are prepared by impregnating cupric compounds on, preferably pretreated, supports with the aid of an aqueous solution of an ammonium salt of a di- or polycarboxylic acid dispersant, such as ammonium citrate, followed by reduction of the cupric compound to the corresponding cuprous compound. The reduction can be performed either by the use of elevated temperature or by the use of a reducing gas preferably carbon monoxide at relatively low temperatures up to 150 DEG C. Methods of synthesis are also disclosed.
