摘要:Provided is a method for the continuous synthesis of 2-cyclopenten-1-one. The continuous synthesis method comprises: loading a catalyst in a continuous reaction device, then continuously conveying cyclopentene, an oxidant and a solvent into the continuous reaction device for an oxidation reaction, and continuously discharging 2-cyclopentene-1-one. In the presence of the catalyst and the solvent, cyclopentene is used as a starting material, and same is directly oxidized by the oxidant, which can avoid the generation of a large amount of halogen-containing three wastes; at the same time, the entire continuous synthesis process is carried out in the continuous reaction device, which can effectively inhibit the occurrence of safety risks during scale-up production; in addition, after the reaction is complete, the product system of the oxidation reaction can be simply concentrated to obtain the target product (2-cyclopenten-1-one). Thus, the purity (up to 98% and above) and separation rate (up to 79%) of the product are greatly improved, and production can be easily scaled up.

标 题:Process for the preparation of ketoalkynoic acids and use of the process in an improved synthesis of 2-(substituted)-cyclo-pentane-1,3,4-triones
发明人：REVERMAN LAWRENCE FRANCIS
权利人:MILES LAB
摘要:Reaction of a 2-methyl-2-(alkenyl)-1,3-dioxolane with an α,ω-dihalogenoalkane to obtain a 2-methyl-2-(ω-chloroalkynyl)-dioxolane, conversion of the latter to a corresponding nitrile, and hydrolysis of the nitrile to form a ketoalkynoic acid is a novel process for preparing the acid. n Use of the process in the synthesis of 2-(substituted)-cyclopentane-1,3,4-triones improves that synthesis.
