dissolve Method
Put all the solvents in the reactor, while stirring, put the PT-17 solid into Reactor; after adding all components, raise the reaction temperature to 90-100 degrees, if using MEK and acetone, the reactor temperature rises to 50-60 degrees, stir for two hours, the maximum pressure of the reactor: 2kg/cm 2, turn off the heating system, continue to stir for an hour and a half, let the reactor cool down naturally, stop stirring; filter the solution, put it into a 200kg barrel

applies Solvent : EK, Toluene, xylene, solvesso, cyclohexanone, acid gas cellulose ester, isophorone, DBE
