Abstract

La presente divulgación se refiere a un proceso continuo para la producción de acefato, comprendiendo dicho proceso las etapas de: poner en contacto fosforoamidotioato de O,O-dimetilo con sulfato de dimetilo para obtener metamidofos; poner en contacto metamidofos con un agente acetilante para obtener acefato. Reivindicación 1: Un proceso para la producción de acefato que comprende a) hacer reaccionar fosforamidotioato de O,O-dimetilo y sulfato de dimetilo para obtener metamidofos y b) convertir metamidofos en acefato en el que dicho proceso es un proceso continuo y las etapas se realizan en un sistema de flujo continuo. Reivindicación 2: El proceso según la reivindicación 1, en el que dicho proceso se realiza a una temperatura que varía de 50ºC a 100ºC. Reivindicación 3: El proceso según la reivindicación 1, en el que el tiempo de residencia de los reactivos en el proceso es de aproximadamente 30 segundos a 1 hora. Reivindicación 4: El proceso según la reivindicación 1 que comprende además convertir metamidofos en acefato poniendo en contacto metamidofos con un agente acetilante en un reactor de flujo continuo para obtener acefato. Reivindicación 13: Un proceso para la producción de fosforoamidotioato de O,O-dimetilo que comprende poner en contacto fosforodicloridotioato de O-metilo con sosa cáustica continuamente en un reactor de flujo avanzado para formar fosforocloridotioato de O,O-dimetilo; y poner en contacto fosforocloridotioato de O,O-dimetilo con una solución de amoniaco continuamente en un reactor de flujo avanzado para formar fosforoamidotioato de O,O-dimetilo. Reivindicación 14: El proceso según la reivindicación 13, en el que la solución de amoniaco se pone en contacto con fosforocloridotioato de O,O-dimetilo a una temperatura que varía de 25ºC a 45ºC. Reivindicación 15: El proceso según la reivindicación 13, en el que la solución de amoniaco comprende NH₃ del 12 al 20%.
