    摘要: The present invention provides a simple, safe and more efficient process for preparing metal salts of valproic acid. The process includes steps of: (i) mixing valproic acid and a metal hydroxide (either dry solid or aqueous solution) in a drier to form a reaction mixture; and (ii) removing water, which is produced during the step of mixing the valproic acid and the metal hydroxide, from the reaction mixture to obtain the desired metal salts of valproic acid.

    摘要: The invention relates to a process for the oxidation of organic compounds by means of oxygen, in which, in a first step, the organic compound and at least part of the oxygen required for the oxidation are introduced into a first reaction zone which is operated isothermally and with backmixing and, in a second step, the reaction mixture from the first reaction zone is introduced into a second reaction zone which is operated adiabatically. The invention further relates to a reactor for carrying out the process, which comprises at least one isothermal reaction zone (3, 5) and an adiabatic reaction zone (7) which are arranged in a reactor shell (8), with each isothermal reaction zone (3, 5) being configured in the form of a jet loop reactor and the adiabatic reaction zone (7) being configured as a bubble column.

    摘要: The present invention relates to a process for producing (2R)-2-propyloctanoic acid, which comprises subjecting (2R)-2-hexyloxirane to a two-carbon adding reaction with ring-opening reaction, followed by a protecting reaction of a hydroxyl group to convert it to a compound represented by formula (I): (wherein X represents an optionally protected hydroxyl group) and then subjecting the compound to a one-carbon adding reaction to convert it to (2R)-2-propyloctanamide, followed by recrystallization and hydrolysis. According to the process of the present invention, (2R)-2-propyloctanoic acid can be produced by less steps as compared with the conventional method without a dangerous reaction.
