| titleOfInvention | Preparation method of hydroximic acid salt collecting agent |
| abstract | The invention provides a preparation method of a hydroximic acid salt collecting agent, which comprises the following specific steps: carrying out grinding reaction on a diester compound shown in a formula (I) and a hydroxylamine salt compound shown in a formula (II) under the action of alkali to obtain a hydroximic acid salt shown in a formula (III) and a dihydric alcohol compound shown in a formula (IV); each of said R 1 Independently an aromatic group, a cycloalkyl group or an alkyl group; the R is 2 Is- (CH) 2 ) n -or- (CH) 2 ) n ‑O‑(CH 2 ) n -, each n is independently 1 ~ 10, NH 2 OH.M includes hydroxylamine hydrochloride, hydroxylamine-O-sulfonate or hydroxylamine nitrate; the base comprises sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, sodium hydrogen phosphate or sodium dihydrogen phosphate; said Y is + Including Na + Or K + (ii) a The alkyl, aryl, cycloalkyl, - (CH) 2 ) n -and- (CH) 2 ) n ‑O‑(CH 2 ) n -may be further optionally mono-or polysubstituted, identically or differently, by hydrogen, fluorine, chlorine, bromine, hydroxyl, amino, carboxyl, alkyl, alkoxy or aryl. The preparation method has the advantages of simple process, short reaction time, simple process, high efficiency and no pollution. |
