AI Technical Summary
Traditional steam heating methods in the production of trichlorfon lead to unstable temperature control, which can easily cause local overheating, increase the probability of side reactions, and pose high-pressure safety hazards.
A heat transfer oil circulation system is adopted, which heats the reactor uniformly through the outer tank and the hot oil heater. Combined with the cooling box and the liquid spray pipe, the temperature is controlled to ensure the temperature uniformity and safety of the reactor.
This achieved uniform temperature control in the reactor, reduced the occurrence of side reactions, improved product quality, and lowered safety hazards.
