What is the approximate accuracy of temperature control for the solution inside the reaction vessel?
It depends on whether you are using automatic control instruments or manual control. There are also climate factors. Pneumatic instruments are affected by the climate in the north, and their control sensitivity may be poor in winter. Electric control can overcome this problem. With manual control, there is of course latency, and the greater the latency, the lower the precision. There are also process requirements; for some temperature parameters, the allowable variation is within a range of 10 degrees either way.
If the temperature is to be controlled below 100 degrees, and the reaction is not intense along with the medium having a fairly good thermal conductivity, a control error of within 0.5°C can be achieved through heat and cold cycling.
Using vertical heat exchange plates instead of coiled tubes in the reactor can provide a larger heat exchange area and a higher heat transfer coefficient. The temperature is extremely stable; the workshop supervisor in Zhejiang described it as being steady. If automatic control and secondary cooling/heating sources are installed as mentioned above, temperature control can be very precise.
