| titleOfInvention | Preparation method of sodium chloride flotation agent |
| abstract | The invention discloses a sodium chloride flotation agent which has a structural formula shown as a formula 1. The sodium chloride flotation agent has hydrophilicity and lipophilicity and has good flotation effect on sodium chloride. The invention also discloses a preparation method of the sodium chloride flotation agent. The preparation method provided by the invention adopts melamine and long-chain halogenated straight-chain alkane as preparation raw materials, wherein the long-chain halogenated straight-chain alkane is used as an N-alkylation reagent, the reaction activity of the preparation method is stronger than that of an alcohol N-alkylation reagent in the prior art, and the preparation method has great advantages particularly when long-carbon-chain alkyl is introduced and difficult-to-alkylate amine alkylation reaction is carried out. The preparation method hardly uses solvent, does not use any catalyst, has short reaction time and low temperature, synthesizes the long carbon chain N-alkylation product of the melamine only by controlling the reaction conditions, and has simple process. |
