1. Check the reaction kettle. Clean and clean.
2. Put A material into the reactor. Close the backflow valve.
3. Began to heat up, open stir around 80 ℃, reflux after turning down the heat oil valve, open the backflow preventer. Slowly up to 210 ℃ reflux heat preservation after 1.5 hours. Cool for B materials, materials out of B, reflux heat preservation after 1 hour, again with 10 ℃ / h temperature to 210 ℃, heat preservation and esterification.
4.Began sampling temperature to 210 ℃ for one hour. Measure the value of viscosity. The viscosity is measured in the previous one hour and the latter half hour. Late to regular sampling, testing viscosity, acid value of qualified, temperature 200 ℃ or so began to turn
5.Prepare the C material ahead of the transfer. When turning the dilute kettle temperature control under 110 ℃. Transfer the remaining C material into the reactor, stirring for about 20 minutes and then add to the dilute cauldron
6.After 1 hour stirring, the sample is adjusted to the viscosity, and when the viscosity is adjusted to the qualified, filter packaging.
The products should be kept in a dry, cool and ventilated place. Prevent sunlight from direct irradiation, and should isolate fire source, away from heat source.
