N,N-Dimethyl-p-toluidine CAS 99-97-8

N,N-Dimethyl-p-toluidine DMPT CAS 99-97-8 Production method: Use dimethyl sulfate as methylating agent to synthesize N,N-dimethyl-p-toluidine under low temperature and normal pressure.

 

Uses: “As an effective photoinitiator for the polymerization of acrylonitrile (AN), the polymerization speed is proportional to the 1.62 power of the AN concentration and the 0.62 power of the DMT concentration. The product is usually used as an accelerator, and can also be used as an additive for the synthesis of unsaturated polyesters and adhesives.
