Abstract

L'invention concerne un procédé d'obtention de chlorures d'acides aromatiques et de 3-chlorophtalide à partir des acides aromatiques correspondants et d'o-pentachloroxylène. Selon ce procédé, on charge, d'une part, le mélange des substances de départ et, d'autre part, le catalyseur, on chauffe jusqu'à 180 degrés C en éliminant HCl formé et on sépare les produits de réaction obtenus. Obtention de chlorures d'acides purs.The invention relates to a process for obtaining chlorides of aromatic acids and 3-chlorophthalide from the corresponding aromatic acids and o-pentachloroxylene. According to this process, on the one hand, the mixture of starting substances and, on the other hand, the catalyst are charged, heated up to 180 degrees C while removing the HCl formed and the reaction products obtained are separated. Obtaining pure acid chlorides.
