The double-layer glass reactor is designed with double-layer glass, and the reaction solvent can be placed in the inner layer to stir the reaction
.
The interlayer can provide different cold and heat sources (refrigerated liquid, hot water or hot oil) for high temperature reaction (with corresponding circulating oil bath, high temperature can reach 300 ℃) or low temperature reaction (with corresponding low temperature refrigerant circulation system) , low temperature up to -80 ℃), or choose heating and cooling integrated circulation equipment
.
Under the set constant temperature condition, in a closed glass reactor, the stirring reaction can be carried out under normal pressure or negative pressure according to the requirements of use, and the reflux distillation of the reaction solution can be carried out
.
When in use, the reaction solution can be drawn out to realize vacuum reaction
.
It is an ideal test and production equipment for modern fine chemical industry, biomedicine and new material synthesis
.
This design makes testing safer and more convenient
.
In daily use and operation, reasonable installation and correct operation of the equipment are the prerequisites to ensure the stable operation of the double-layer glass reactor
.
According to the industry, in the process of working in the double-layer glass reactor, some places are actually very easy to be ignored by users
.
In this regard, the industry has made a summary based on experience, and the author has made a brief arrangement
.
First, pay attention to heat preservation
.
It is understood that due to the small thickness of the interlayer in the double-layer glass reactor, the thermal insulation performance is poor
.
In the process of using high temperature and low temperature, users need to use thermal insulation materials to protect the kettle body
.
At the same time, the user needs to wrap the reactor body and the liquid-conducting pipe with thermal insulation material, and pay attention to the thickness of the thermal insulation layer to ensure a good thermal insulation effect
.
Second, the choice of temperature control medium
.
Generally speaking, according to the required reaction temperature, the user will select a temperature control medium with different properties as the heat transmission medium for the reaction
.
Choose ice ethanol bath for low temperature, water bath for normal temperature, and oil bath for high temperature
.
It is recommended that when using low temperature or high temperature, pay attention to choosing the appropriate medium, the key is viscosity
.
"If the viscosity of the medium is too large, the circulating pump may not be able to carry it, and the medium circulation effect is not good, and the required temperature control effect cannot be achieved
.
If the high-power circulating pump is replaced rashly, the pressure of the medium pressed into it is too large, which is easy to damage the double-layer glass reactor.
Lining, the reactor ruptured
.
” It is understood that manufacturers usually choose the corresponding heating medium according to their own products
.
Third, the storage location needs to be reasonable
.
The double-layer glass reactor is used as a reaction amplification test device, and the volume is usually 50-150L, and the volume can be customized in specific cases.
Therefore, the scale of the test should not be underestimated
.
Since the kettle body is made of glass, stainless steel is the bracket and the legs are casters, the storage location needs to be carefully selected
.
As far as storage conditions are concerned, although the casters can be fixed with foot buckles, the stability is not strong
.
Therefore, during the storage process, the user should choose a flat place to lay it, and keep the mechanical stirring center consistent with the reaction kettle, otherwise it will easily shake and become unstable and cause safety accidents
.
In addition, it must be placed in a well-ventilated place
.
Fourth, feeding precautions
.
Since the double-layer glass reactor is an independent reaction rack and the reserved feeding port is small, the feeding process is difficult
.
In this regard, it is suggested that solid reagents can be formulated into solutions and added to the kettle, and liquid reagents can be pumped into the kettle through the matching water pump or oil pump
.
In particular, when the reaction material is added to the reaction kettle through a constant pressure dropping funnel or a common dropping funnel, a corresponding mobile ladder needs to be matched so that the staff can add the test material
.
