About DMAC and DMF in the amino industry
Not. I design the spandex system engineering. Including design, manufacturing aminotomy equipment. For the process of refining, aggregation, spinning, public engineering and other processes.

As far as I understand, DMAC can be recycled, Jiangsu Shuangliang, Yantai spandex, and Huafeng aminotrans still use it. I represent Robonhaas ion exchange resin, with DMAC purified resins, Shuangliang, Yantai, and Huafeng are all our customers. If you need it, please call 15900676576 Mr. Lu (Sales)

The waste liquid containing DMAC was extracted with chloroform solvent, and the DMAC concentration in the waste liquid should not be too high.The extraction solution can get a relatively pure DMAC after decontamination and dehydration.

As far as I know, almost all the ammonia production is DMAC, which is a dimethyl acetamide, and the early spandneida production process uses di metamimam (DMF). Use DMAC to instead of DMF, there are about the following advantages: 1. DMF is more volatile, flammable and explosive, and the risk factor in use is greater. \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; 2.DMF is more toxic and the production process is not environmentally friendly. \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; \u0026 nbsp; 3. The polymer produced by new polymerization techniques is better to dissolve in DMAC, and the original items are low in viscosity. It is conducive to production and operation. DMAC in production is recycled. After the spinning wind system contains DMAC gases, after condensing, a thick DMAC containing a certain moisture and other impurities. The distillation tower in other impurities in the DMAC to form pure DMAC for each process. Generally speaking, the DMAC indicators of spandex production requirements are moisture \u0026 lt; 60ppm, acidity \u0026 lt; 100ppm, alkali \u0026 lt; 2ppm, conductivity \u0026 lt; 0.05us/cm2.
