Step 4: the temperature in sulfonating reaction kettle is down to 100 DEG C after wait react 1-2h, to it inside 1,2-dichloros are added
Ethane, then temperature is risen to 160-180 DEG C；
Step 5: its 1,2-internal dichloroethanes distilled is come out by fractionating device, to its internal liquid in pure color it
Afterwards, stop heating；
Step 6: stopping stirring after to 0.5-1h, that is, first motor, the second motor and stirring motor are closed, due to the first bullet
The active force of spring and second spring, so that catch bar is retracted into initial position；
It is filtered under diminished pressure Step 7: liquid is drained into next filter-pressing cauldron, can be obtained the bisphenol S of high-purity.
