Abstract
La présente invention a pour objet un procédé de préparation d esters d'acides thiocarbamiques. Selon ce procédé : a. On fait réagir COS avec une amine en milieu anhydre, avec un rapport molaire COS/amine au moins égal à 0,502 environ, à une température supérieure ou égale à + 10 degrés C, et sous une pression absolue supérieure à 0; b. On fait réagir le produit obtenu dans l'étape a avec un halogénure organique en milieu anhydre, à une température d'au moins 60 degrés C et une pression absolue supérieure à 0, pour obtenir un thiocarbamate et un sel; c. On isole le thiocarbamate formé à partir du mélange réactionnel de l'étape b. Elle se rapporte à la préparation des esters d'acides thiocarbamiques.The present invention relates to a process for the preparation of esters of thiocarbamic acids. According to this process: a. COS is reacted with an amine in an anhydrous medium, with a COS / amine molar ratio of at least approximately 0.502, at a temperature greater than or equal to + 10 degrees C, and under an absolute pressure greater than 0; b. The product obtained in step a is reacted with an organic halide in an anhydrous medium, at a temperature of at least 60 ° C. and an absolute pressure greater than 0, to obtain a thiocarbamate and a salt; vs. The thiocarbamate formed is isolated from the reaction mixture of step b. It relates to the preparation of esters of thiocarbamic acids.
