发明名称 Process for preparing o-alkylhydroxylamine salts without the isolation of intermediates
摘要 This invention relates to a process for preparing aqueous solutions of O-alkylhydroxylamine salts. The process involves converting hydroxylamine salts to their O-alkyl derivatives without the isolation of intermediates. More specifically, the process involves three steps. The first step, Step (A), involves forming a ketoxime. The second step, Step (B), involves adding an alkylating agent to the ketoxime formed in Step (A). The third step, Step (C), involves hydrolysing the alkylated ketoxime formed in Step (B) to yield an O-alkylhydroxylamine salt. O-alkylhydroxylamine salts are important intermediates in the preparation of herbicides.
