What are the easily neglected parts of double glass reactor

With the development of technology, the development of double-layer glass reactor is gradually accelerating, the types and functions are increasing, and it is widely used The double glass reactor can stir reaction under normal pressure or negative pressure according to the use requirements, and can carry out reflux and distillation of reaction solution Double window digital display shows the speed and temperature measurement value It has high temperature measurement accuracy, small error and effectively improves the working efficiency In the process of double glass reactor, some parts are easy to be ignored by customers What is it? We summarize the experience as follows: first, due to the small thickness of interlayer in the middle of double glass reactor, the insulation performance of insulation medium is poor In the process of using high and low temperature, it is necessary to use thermal insulation materials to protect the kettle body For the reactor body and the liquid pipe, they need to be wrapped with thermal insulation materials, and pay attention to the thickness of the thermal insulation layer to ensure a better thermal insulation effect 2 The choice of temperature control medium according to the required reaction temperature, choose different properties of temperature control medium as the reaction heat transmission medium Low temperature, choose ice ethanol bath; normal temperature, choose water bath; high temperature, choose oil bath When using low or high temperature, pay attention to choose the right medium, the key is viscosity If the viscosity of the medium is too high, the circulating pump may not move, and the medium circulation effect is not good, so the required temperature control effect cannot be achieved It is easy to damage the inner lining of the double glass reaction kettle and the reaction kettle is broken if the high-power circulating pump is replaced rashly and the medium pressure is too large Usually, the manufacturer will choose the corresponding heating medium according to their own products 3 The double-layer glass reactor at the storage location is used as the reaction amplification test device, with a volume of 50-150l, which can be customized under specific circumstances Therefore, the scale of the test should not be underestimated As the kettle body is made of glass, stainless steel is the support and the foot of the scaffold is the caster, the storage location needs to be carefully selected Although castors can be fixed with shackles, they are not stable Therefore, during the storage, pay attention to choose a flat place, lay it flat, and keep the mechanical mixing center consistent with the reactor, otherwise it is easy to shake unsteadily, resulting in safety accidents The height of the double-layer glass reactor is about 1.5m, and the overall reactor is about 2m with the straight condensation pipe General floor ventilation kitchen cannot be placed, but it must be placed in a place with good ventilation position IV precautions for feeding: the double-layer glass reactor is an independent reaction rack, unlike the industrial reactor, which has a reaction bench, and the reserved feeding port is small, so the feeding process is relatively difficult Suggestion: for solid reagents, it is recommended to prepare solution and add it into the kettle; for liquid reagents, they can be pumped into the kettle through matched water pump or oil pump In particular, the reaction material is added to the reactor through constant pressure drop funnel or common drop funnel, and corresponding mobile ladder is required to facilitate the staff to add the test material According to the temperature, reflux and pressure of the reaction, the evaluation is carried out and the appropriate amount of material is added Generally, it should not exceed 2 / 3 of the kettle body The above aspects are easy to be ignored by many customers Small details are often more important I hope the above contents can give customers some reference and help!
