    摘要: A process for the preparation of copper quinolinate in which quinoline is oxidized by hydrogen peroxide in sulfuric acid in the presence of copper sulfate wherein the reaction is carried out at a pressure of less than 400 mm Hg. The reduced pressure enables the reaction to be performed at higher temperatures and with greater control; also the reaction time is shortened and the yield improved.Copper quinolinate is used to prepare quinolinic acid which is the starting material for some chromogenic materials used in the pressure-sensitive record material field.

    摘要: A process for the preparation of copper quinolinate in which quinoline is oxidized by hydrogen peroxide in 10 to 30% sulfuric acid in the presence of copper sulfate at a temperature of 55.degree. to 75.degree. C., the molar ratio of sulfuric acid to quinoline being greater than 1:1. The concentration and amount of sulfuric acid enable greater control of the reaction temperature and result in copper quinolate in improved yield and purity.Copper quinolinate is used to prepare quinolinic acid which is the starting material for some chromogenic materials used in the pressure-sensitive record material field.

    摘要: This invention relates to an improvement in the process for preparation of 2-(amylbenzoyl)benzoic acid containing a high percentage of 2-(t-amylbenzoyl)benzoic acid. More particularly it relates to a process for preparation of 2-(amylbenozyl)benzoic acid wherein said 2-(amylbenzoyl)benzoic acid is prepared by reacting t-amylbenzene with phthalic anhydride in the presence of Lewis acid, characterized by that 2-(amylbenzoyl)benzoic acid containing a high percentage of 2-(t-amylbenzoyl)benzoic acid is produced by suppressing the undesirable isomerization reaction of the amyl radical by applying one of the means selected from the group consisting of the means of introducing an inert gas into the reaction system and the means of reducing the pressure of the reaction system. 2-(Amylbenzoyl)benzoic acid is a compound useful as the starting material of preparation of 2-amylanthraquinone which is an effective organic catalyst in the manufacture of hydrogen peroxide.
