Low concentrations of Industrial Waste Recycling and waste acid pickling method metal hydrometallurgical leaching fluid and other waste acid and acidic wastewater treatment project has been environmental problems. By heat or freeze recovered waste acid, its operating costs are very expensive, with lime and waste of resources. The main purpose is to recover the acid recycling machine waste residual acid, hydrochloric acid on the street, to reduce production costs, the type of hydrochloric acid to reduce the amount of goods, while the acid recovery wastewater treatment is an important part, after the price of hydrochloric acid, waste acid recovery has in favor of recycling waste water metal ions, organic material. Block method acid recovery machine technology only Japan, Germany and other countries to master the few, the amount of processing equipment monomers are relatively small. And only use in metal pickling industry. Xi'an Central Division Water Co., after years of study, in the efforts of a dozen experts, not only developed metal waste recycling equipment, and individual equipment handling capacity from the international common 6T / d, upgrade to 60T / d , is expected to recently increased to 120T / d; and will also handle applications pickle liquor from a single metal, expanded to non-metallic minerals, vanadium extraction, pharmaceutical raw materials extraction, organic chemical synthesis, sulfuric acid in various fields . Because we are professional so we do better physical properties, credit-quality first quality guarantee fair prices hexanoyl chloride material: GB No. No. 81115CAS 142-61-0 Formula C6H11ClO; CH3 (CH2) 4CClO Appearance colorless liquid Molecular weight 134.61 flash point 50 ℃ Boiling point: 151 ~ 153 ℃ Solubility insoluble in ether, chloroform and most [2] The organic solvent density relative density (water = 1) 0.97 Stability stable risk Marker 20 (corrosive acid) main purpose for organic The synthesis method consists of positive ethanol and thionyl chloride derived reaction. The thionyl chloride was mixed with n-hexyl acid at 50-70 ℃, reaction at 70-90 ℃ 4h. Distillation, collecting 147-160 ℃ distillate, hexanoyl chloride. Use 1 for organic synthesis intermediates. For the preparation of anti-fungal drugs have acid tribromobenzene ester, also as a liquid crystal intermediates. 2. for organic synthesis. Used as organic synthesis of the block hydrochloric acid acylating agent | Zhengzhou Longda Chemical | hydrochloric acid effect provided by the Zhengzhou Longda Chemical Products Limited. On the street hydrochloride | Zhengzhou Longda Chemical | hydrochloric role Zhengzhou Longda Chemical Products Co., Ltd.
