| chemical properties | white needle crystal. Melting point 166-168 ℃ (anhydrous),84-85 ℃ (containing crystal water). Easily soluble in alcohol and ether, slightly soluble in benzene and petroleum ether, hardly soluble in water. |
| Uses | This product can form stable complexes with nickel, platinum, palladium, rhenium, etc., and is used as a chelating extractant to extract and separate nickel, palladium, etc. |
| production method | is prepared from furanoyl (see previous article). Mix water with 8 times the weight of the group and excess hydroxylamine hydrochloride and heat it on a water bath until it is completely dissolved. Pour the solution into boiling water 6 times the base volume and keep boiling for a few minutes. Cooling, filtering out the precipitate, washing with a large amount of water, and then evaporating and drying at 30-90 ℃ is the finished product. |
