Abstract

Procédé de préparation simultanée d'acide N-phosphonométhyl-imino-diacétique et de chlorure d'acide inférieur par emploi d'acide imino-diacétique et de trichlorure de phosphore, procédé qui consiste à faire réagir le tichlorure de phosphore et l'acide carboxylique en C1-C4 en un rapport molaire d'environ 1/3 à une température entre 0 et 20 degrés C, à séparer la phase acide phosphorique formée de la phase chlorure d'acide carboxylique et à isoler le chlorure d'acide carboxylique, puis après dilution dans de l'eau, à faire réagir la phase acide phosphoreux contenant également l'acide carboxylique et le chlorure d'acide carboxylique avec l'acide imino-diacétique et la solution aqueuse de formaldéhyde, le rapport molaire acide imino-diacétique/acide phosphoreux/formaldéhyde étant de l'ordre de 1/1 à 1,1/1 à 1,2, en présence d'un acide minéral fort, de préférence en l'acide chlorhydrique, que l'on ajoute à une température comprise entre 60 et 120 degrés C, puis à évaporer le mélange jusqu'à ce que se séparent les cristaux.Process for the simultaneous preparation of N-phosphonomethylimino-diacetic acid and lower acid chloride by using imino-diacetic acid and phosphorus trichloride, process which consists in reacting the phosphorus tichloride and the carboxylic acid in C1-C4 in a molar ratio of about 1/3 at a temperature between 0 and 20 degrees C, separating the phosphoric acid phase formed from the carboxylic acid chloride phase and isolating the carboxylic acid chloride, then after dilution in water, reacting the phosphorous acid phase also containing the carboxylic acid and the carboxylic acid chloride with the imino-diacetic acid and the aqueous formaldehyde solution, the imino-diacetic acid / molar ratio phosphorous acid / formaldehyde being of the order of 1/1 to 1.1 / 1 to 1.2, in the presence of a strong mineral acid, preferably hydrochloric acid, which is added at a temperature included between 60 and 120 degrees C, then evaporate the mixture until the crystals separate.
