Abstract
Η εφεύρεσις σχετίζεται με την ταυτόχρονη παραγωγή Ν-φωσφονο-μεθυλο-ιμινο-διοξικού οξέος και χλωριούχου άλατος καρβοξυλικού οξέος. Σύμφωνα με την εφεύρεση, τριχλωριούχος φωσφόρος και καρβοξυλικό οξύ C1-4 αντιδρούν, κατά προτίμηση υπό μοριακή αναλογία 1:3 και με θερμοκρασία μεταξύ 0 και 20 βαθμούς Κελσίου, και η σχηματιζόμενη φωσφορική όξινη φάσις διαχωρίζεται από το χλωριούχο άλας καρβοξυλικού οξέος και απομονώνεται το χλωριούχο άλας του καρβοξυλικού οξέος, αντιδρά δε επίσης η φωσφορική όξινη φάσις που περιέχει καρβοξυλικό οξύ και χλωριούχο άλας καρβοξυλικού οξέος, μετά την αραίωσή της με νερό, με ιμινο-διοξικό οξύ και με το υδατικό διάλυμα φορμαλδεϋδης, ενώ η μοριακή αναλογία του ιμινο-διοξικού οξέος προς το φωσφορικό οξύ και την φορμαλδεϋδη είναι περίπου 1:1-1, 1:1,-1-2, επί παρουσία ενός προστιθέμενου ισχυρού ορυκτού οξέος, κατά προτίμηση δε υδροχλωρικού οξέος, σε θερμοκρασία από 60 έως 120 βαθμών Κελσίου, και κατόπιν το μείγμα εξατμίζεται μέχρι τον διαχωρισμό των κρυστάλλων.ωThe invention relates to the simultaneous production of N-phosphono-methyl-imino-diacetic acid and carboxylic acid chloride. According to the invention, phosphorus trichloride and C1-4 carboxylic acid are reacted, preferably in a molar ratio of 1:3 and with a temperature between 0 and 20 degrees Celsius, and the formed phosphoric acid phase is separated from the carboxylic acid chloride salt and the chloride is isolated carboxylic acid salt, the phosphoric acid phase containing carboxylic acid and carboxylic acid salt chloride also reacts, after diluting it with water, with imino-diacetic acid and with the aqueous formaldehyde solution, while the molar ratio of imino-diacetic acid to phosphoric acid and formaldehyde is approximately 1:1-1, 1:1,-1-2, in the presence of an added strong mineral acid, preferably hydrochloric acid, at a temperature of 60 to 120 degrees Celsius, and then the mixture is evaporated until the separation of crystals.o
