Production method
1.Complex decomposition method: reaction between ammonium sulfate and sodium chloride
2.Combined-soda method: adding fine salt to ammonium chloride mother liquor
3.Re-crystallization of raw ammonium chloride
4.Vapor method synthesis method: hydrogen chloride gas pass through the absorption tower and contact with cyclic mother liquor and generate saturated hydrogen chloride with ammonium chloride solution, then react with ammonia.
