Title:
ALKYL THIOETHER ETHYL HYDROXIMIC ACID BENEFICIATION AGENT, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/042814
Kind Code:
A1
Abstract:
Disclosed are an alkyl thioether ethyl hydroximic acid beneficiation agent, a preparation method therefor and a use thereof. The alkyl thioether ethyl hydroximic acid molecule has two functional groups, i.e. a thioether group and a hydroximic acid group, and the molecule is obtained by the esterification of alkyl thioether acetic acid and methanol, and then the hydroximation of hydroxylamine and an alkali. The alkyl thioether ethyl hydroximic acid beneficiation agent can be used as a collecting agent for mineral flotation. The preparation method therefor is simple and the yield thereof is high. The thioether group and the hydroximic acid group in the molecule have a synergistic effect, which can effectively improve the collection performance thereof.
