| titleOfInvention | Process for the preparation of n,o-dialkylhydroxylamines |
| abstract | 1. A PROCESS FOR THE PREPARATION OF A N,O-DIALKYLHYDROXYLAMINE, WHICH COMPRISES THE STEPS OF (A) REACTING JYDROXYLAMINE, A SALT OF HYDROXYLAMINE OR A HYDROXYLAMINE DISULPHONATE WITH AN ALDEHYDE OR A KETONE CAPABLE OF FORMING AN OXIME UNDER REACTION CONDITIONS; (B) ALKYLATING THE OXIMINO COMPOUND OBTAINED IN (A) WITH AN ALKYLATING AGENT; (C) QUATERNISING THE PRODUCT OBTAINED IN (B) WITH AN ALKYLATING AGENT WITH EXCLUSION OF MOISTURE AT A TEMPERATURE IN THE RANGE OF FROM 50* TO 140*C. TO OBTAIN A N-ALKYLIDENE - N,O - DIALKYLAMMONIUM SALT OF THE FORMULA CH2=N(+)(-O-ALKYL'')-ALKYL" Z(-) IN WHICH ALKYL'' AND ARLKYL'' REPRESENTS THE ALKYL RADICALS INTRODUCED IN STEPS (B) AND (C) AND Z REPRESENTS THE RADICAL ORIGINATING FROM THE QUATERNIZING AGENT; AND (D) HYDROLYSING THE N-ALKYLIDENE-N,O-DIALKYL-AMMONIUM SALT OBTAINED IN (C) UNDER ACID CONDITIONS TO OBTAIN A N,O-DIALKYL-HYDROXYLAMINE. |
