solvent used

Dissolution method
1. Put all the solvent into the reactor
2. Put ES-812 solid into the reactor while stirring
3. After adding all the ingredients, raise the temperature of the reactor to 90-100 degrees and stir for 2 hours. Reactor maximum pressure: 2kg/cm2
4. Turn off the heating system and continue stirring for one and a half hours to allow the temperature of the reactor to drop naturally.
5. Stop stirring, the solution needs to be filtered, and put the solution into a 200kg bucket

MEK, Toluene, Acetone, Solvesso, Cyclohexanone, Cellulose Acetate, Isophorone, DBE, etc
