The glass reactor is sealed under the set constant temperature. It can be stirred and reacted under normal pressure or negative pressure according to the requirements of use, and can be used for reflux and distillation of the reaction solution. It is well known that reasonable installation and correct operation of equipment are essential The premise of ensuring the stable operation of the glass reactor.
First of all, pay attention to heat preservation when using it. It is understood that due to the small thickness of the interlayer in the middle of the 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 pipes with thermal insulation materials, and pay attention to the thickness of the thermal insulation layer to ensure a good thermal insulation effect.
Temperature control medium selection. 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.

Abstract: Oil deacidification is an important step in food processing, which aims to remove free fatty acids in oil and improve its quality and stability. Traditional deacidification methods have some limitations, such as low efficiency, high energy consumption, and loss of nutrients. In recent years, molecular distillation technology has gradually attracted attention as a new deacidification method. This article will introduce the application of molecular distillation in oil deacidification, including the principle, operation process and advantages, and focus on the outstanding advantages of Aishengke in molecular distillation technology.
Vitamins are products that are closely related to people's lives, and have become one of the main bulk products in the international pharmaceutical and health care products market. The amount of vitamin E is the largest, followed by vitamin A, vitamin C, vitamin D and so on. With the growth of economy and the improvement of people's living standards, the demand for vitamin products will further increase, and people's requirements for their quality and grade will also further increase. Therefore, as an important separation technology in the production of many vitamins, molecular Distillation technology will also play an increasingly important role in the vitamin industry.
Glyceryl monostearate (GMS), abbreviated as monoglyceride, is produced from natural vegetable oils and fats. The active ingredient is purified by molecular distillation technology to more than 90%, also known as molecular distillation monoglyceride. It is the most widely used food Additives, safe to use in the production and processing of food, medicine, plastics, etc., account for more than half of the emulsifier consumption in the market.
The principle of molecular distillation is to make use of the different degrees of affinity between different molecules. By controlling the conditions such as temperature and pressure, the mixture begins to vaporize. Different components in the vapor form liquids in the condenser and are separated according to their boiling points. This distillation method not only has a good separation effect, but also can be repeatedly separated and purified, and is widely used in chemical, pharmaceutical and other fields.
Molecular distillation is a common chemical method used to separate and purify compounds. In the pharmaceutical industry, molecular distillation is widely used in pharmaceutical purification. This article will focus on the application of molecular distillation in pharmaceutical purification and provide some specific examples.
Laboratory vacuum distillation equipment has undergone significant advancements in recent years, driven by the need for higher efficiency, improved safety, and enhanced user experience.
