Title:
再生可能原料を使用するメチルメルカプトプロピオンアルデヒドおよびメチオニンの製造方法
Document Type and Number:
Japanese Patent JP2012509304
Kind Code:
A
Abstract:
The present invention relates to a method for manufacturing methylmercaptopropionaldehyde (MMP) including at least the following steps: (a) dehydrating glycerol to acrolein from an aqueous solution of glycerol in the presence of an acid catalyst; (b) purifying the aqueous flux from step (a) to obtain a flux of acrolein containing at least 15 wt % of water relative to the acrolein; (c) causing a reaction of the acrolein flux obtained in step (b) with methylmercaptan in the presence of a catalyst; (d) optionally purifying the product obtained in step (c). The method of the invention can also include a reaction of the product obtained in step (c) or (d) with hydrocyanic acid, or sodium cyanide during a step (e) followed by a subsequent transformation to produce methionine or methionine hydroxyanalogue, which can then optionally be purified. The additional use of methylmercaptan and/or hydrocyanic acid derived from biomass as raw materials in the method according to the invention makes it possible to obtain MMP, methionine or methionine hydroxyanalogue made up of 100% organic carbon from renewable sources.
