Product Overview

Distillation still

Distillation stillThe types of distillation stills mainly include organic heat carrier heated distillation stills and vacuum distillation stills. ‌‌Organic heat carrier heated distillation stills‌: This type of distillation still uses organic matter with high boiling point and relatively low saturated vapor pressure as the heat carrier, such as naphthalene, biphenyl, diphenyl ether, etc. In practical applications, a mixture of biphenyl and diphenyl ether (industrially known as Utro liquid or Dawson oil) is widely used due to its low melting point. This heating method is suitable for distillation processes that require gentle heating, and can effectively control the temperature to avoid overheating or decomposition of the material.‌Vacuum distillation still‌: This is a separation technology carried out under high vacuum conditions, with the characteristics of low distillation temperature, high system vacuum, short material heating time, and high separation degree. This technology is particularly suitable for separating high-boiling point, heat-sensitive and easily oxidized substances, so it is widely used in the extraction of vitamins and effective ingredients of Chinese herbal medicines in the pharmaceutical industry, petrochemicals, food industry, cosmetics industry and agriculture. These characteristics of the vacuum still make it an ideal choice for handling sensitive substances because it can reduce oxidation and decomposition of substances while improving separation efficiency.1. Types and characteristics of stillsThe still is a common chemical experimental equipment, mainly used to achieve purification, separation, extraction and other operations. At present, there are three main types of common stills, namely glass stills, stainless steel stills and enamel stills. Their main characteristics are as follows:Type | FeaturesGlass still has good chemical stability and transparency, and can observe the reaction process and degree of purificationStainless steel still: has excellent corrosion resistance, strength and high temperature resistance, suitable for distillation of high pressure, high temperature and toxic and harmful materialsEnamel still: has excellent chemical stability, corrosion resistance and wear resistance, especially suitable for distillation operations in chemical, pharmaceutical, food and other industries

3. Application scenariosAccording to the characteristics of different types of distillation kettles, they can be used in the following scenarios:1. Glass distillation kettle: suitable for the purification and separation of organic matter and some unstable compounds. Because glass is transparent, it can also be used to observe the reaction process and the degree of purification.2. Stainless steel distillation kettle: It has good strength and corrosion resistance, so it is suitable for the distillation of high pressure, high temperature and some toxic and harmful materials.3. Enamel distillation kettle: Its excellent corrosion resistance and chemical stability make it particularly suitable for distillation operations in the chemical, pharmaceutical, food and other industries.In short, the distillation kettle is a common and practical chemical experimental equipment. Choosing a suitable distillation kettle during the experiment can improve the efficiency and safety of the experiment, and thus improve the quality and quantity of the experimental results.

How to choose a distillation reactor that suits you1. What are the differences between distillation reactors of different capacities?The capacity of a distillation reactor is one of the important factors to consider when choosing. According to the capacity, distillation reactors can be divided into atmospheric pressure reactors, large reactors, micro reactors and other types. Atmospheric pressure reactors are suitable for small-scale operations, large reactors are suitable for large-scale industrial production, and micro reactors are suitable for micro-experiments and small-batch production. Therefore, it is very important to choose the appropriate capacity, which will directly affect the efficiency and safety of the reaction process.2. What are the differences between distillation reactors with different operating modes?The operating mode of a distillation reactor is also one of the important factors to consider when choosing. Common operating modes include manual operation, semi-automatic operation and fully automatic operation. Manual operation is relatively simple, but it has high manufacturing requirements and is not suitable for places where the reaction process requires precise control. Semi-automatic and fully automatic operations are more suitable for environments that require precise control and long-term operation.3. What are the differences between distillation reactors of different materials?The material of a distillation reactor is directly related to its service life and reaction quality, so it is also very important to choose a material that suits you. Common materials include stainless steel, glass, titanium alloy, etc. Stainless steel reactors generally have a long service life, but are not suitable for reacting special substances; glass reactors have good transparency and can clearly observe the reaction process, but their service life is relatively short; titanium alloy reactors are relatively stable and suitable for environments with high reaction requirements.4. How to choose a distillation reactor that suits you?Choosing a distillation reactor that suits you should comprehensively consider multiple factors such as capacity, operation mode, material, and reaction requirements. For small-scale experiments, you can choose a normal pressure reactor or a micro reactor; for large-scale industrial production, you can choose a large reactor; for environments that require precise control and long-term operation, you can choose semi-automatic or fully automated operation; for reacting special substances, you need to choose stainless steel, glass, titanium alloy and other materials that suit you according to actual conditions.[Summary] Choosing a distillation reactor that suits you can not only improve the reaction efficiency and quality, but also ensure the safety of the reaction. Therefore, when choosing a distillation reactor, you must fully consider factors such as capacity, operation mode, and material in order to choose a distillation reactor that suits you.
