The Double-layer Glass Reactor can be used to conduct high temperature, low temperature and vacuum reaction experiments. Its operation is simple and the reaction process is plain and convenient to control. The Double-layer Glass Reactor is an ideal piece of equipment used for modern chemical samples, petrochemical engineering, pilot-scale sample experiments, bio-pharmaceuticals and new material synthesis. However, we have received customer complaints that the temperature increase rate of the Double-layer Glass Reactor is too slow, which costs them a lot of time and energy. In fact, larger capacity reactors rise in temperature more slowly!
The following suggestions are given to our customers regarding this concern:
I. Use a special insulated cotton to wrap the double-layer glass reactor up in order to realize heat insulation, effectively prevent excessive heat loss and improve the temperature increase rate.
II. Optimize the appropriate temperature setting of the high temperature oil bath pot (high temperature circulator) to allow the Double-layer Glass Reactor to receive higher temperatures and to reduce the heating duration. If the reaction temperature of the Double-layer Glass Reactor approaches the operating temperature, lower the temperature of the high temperature oil bath pot (high temperature circulator) to the actual operating temperature.
For example, if the actual operating temperature is 100℃, set the temperature of the high temperature oil bath pot (high temperature circulator) to 120℃. If the temperature of the Double-layer Glass Reactor increases to about 90℃, set the temperature of the high temperature oil bath pot to 100℃. This will effectively improve the temperature increase rate and shorten the waiting time.
III. Do not fill up the Double-layer Glass Reactor with solution in one go, as this may affect the temperature increase rate. We recommend feeding in the solution in batches, with the content of the first batch being half the capacity; feed the materials into the reactor when the temperature is approaching the required temperature, and feed the solution in according to the above methods! This can also effectively improve the temperature increase rate!
With regard to the three methods of improving the temperature increase rate and working efficiency outlined above, pharmaceutical enterprises should choose the appropriate method according to their specific situations.
