Abstract

La présente invention a pour objet un procédé pour préparer des chlorothioformiates. Pour préparer des chlorothioformiates d'alkyle, de cycloalkyle inférieur, de cycloalkylméthyle inférieur, d'alcényle inférieur, de phényle, de benzyle, de chlorophényle et de certains halogénoalkyles, on fait réagir le thiol correspondant 1 avec du phosgène 2 en deux stades 10 et 11 ou l'on opère en phase liquide continue en présence d'un catalyseur constitué de charbon activé L'invention s'applique en particulier à la production d'esters chlorothioformiques contenant très peu de sous-produits de type disulfure avec un accroissement de la capacité globale de production.The present invention relates to a process for preparing chlorothioformates. To prepare chlorothioformates of alkyl, lower cycloalkyl, lower cycloalkylmethyl, lower alkenyl, phenyl, benzyl, chlorophenyl and certain haloalkyls, the corresponding thiol 1 is reacted with phosgene 2 in two stages 10 and 11 or the operation is carried out in a continuous liquid phase in the presence of a catalyst consisting of activated carbon The invention applies in particular to the production of chlorothioformic esters containing very few by-products of disulfide type with an increase in the overall production capacity.
