Yield: 99.7%

Reaction Conditions:

with MA-PVC in water at 15;Temperature;

Steps:

12 Example 12
Using embodiment 2 MA-PVC solid catalyst is filled in the glass tubular reactor, the temperature in the jacket 15 °C. The metering pump delivers 500.0g20 . 0% aqueous solution of sodium thiocyanate (98.0%, 1 . 21mol, industrial), 132.8g methylchloroformate (99.0%, 1 . 39mol, industrial) to respectively 450.0g/h, 119 . 5g/h in the continuous reactor. Maintaining the feeding speed of the material in the reactor 10 min, to obtain isothiocyano a acid methyl ester product 142.4g, content 99.2% (GC, external standard method), the yield is 99.7% (by thiocyanate sodium idea ), catalyst can be continuously used for 300h, the catalytic effect of direct incineration processing.
