PROCEDURE FOR OBTAINING DERIVATIVES GLICIN-N, N-DIACETIC ACID THROUGH REACTION DERIVATIVES OF GLYCINE OR ITS PRECURSORS WITH FORMALDEHYDE AND CYANHYDRIC ACID, OR IMINODIACETIC ACID ACID AND ACID ACID ACID AND ACID ACIDES.

摘要

OBTAINING OF DERIVATIVES OF ACID GLICIN-N, N-DIACETIC I IN WHERE R IS ALKYL OPTIONALLY SUBSTITUTED, ALKYNYL, GROUPS ALCOXILATO, FENILALQUILO, FENILO, A HETEROCICLICO RING, WHICH IS A YELLOW ANIEN-A-YELLOW RING YM IS HYDROGEN, ALKALINE METAL, ALKALINE TERRAINE, AMMONIUM OR AMMONIUM SUBSTITUTED WITH THE CORRESPONDING ESTIMETRIC AMOUNTS, BY REACTION OF A) THE CORRESPONDING GLYCINES OR GULIN OILS OF GULIN AND OULIN GULFIES. STARTING MATERIAL THE CITED DERIVATIVES OF GLYCINE WITH FORMALDEHYDE AND CYANHYDRIC ACID IN AQUEOUS MEDIUM AT A PH OF 0 TO 11, OB) IMINODIACETONITRILE OR IMINODIACETIC ACID WITH THE CORRESPONDING MONOALDEHIDES OF FORMULA R-CHOO CHO CYANHYDRICAL IN AQUEOUS MEDIUM AND AT A PH FROM 0 TO 11, AND OPTIONALLY SUBSEQUENT SAPONIFICATION OF THE NITRILE FUNCTIONS PRESENT USING STARTING COMMOMATERIAL THE UNPURIFIED RAW MATERIAL THAT APPEARS IN THE TECHNICAL SYNTHESIS OF THE DERIVATIVES OF GLYCINE OR OF ITS PREVIOUS STAGES OR OF IMINODIACETONITRILE OR OF IMINODIACETIC ACID, OR THE BLEACH THAT IS FORMED IN THESE SYNTHESIS.
