Laboratory instruments rotary evaporators are mainly used for continuous distillation of large quantities of volatile solvents under reduced pressure. In particular, the reaction products can be separated and purified by the concentration of extraction solution and the distillation of the receiving solution during chromatographic separation. The basic principle of a rotaryvaporizer is reduced pressure distillation, that is,under reduced pressure, when the solvent is distilled, the distillation flask is continuously rotating
Structure: The distillation flask is a pear-shaped or round-bottom flask with a standard grinding interface, connected to a pressure relief pump by a high reflux serpentine condensing tube, and another opening of the reflux condensing tube is connected to a receiving flask with a grinding mouth for receiving the evaporated organic solvent. There is a three-way piston between the condensing tube and the decompression pump. When the system is communicated with the atmosphere, the distillation flask and the liquid flask can be removed and the solvent can be transferred. When the system is communicated with the decompression pump, the system should be in the state of decompression. When using, it should be DECOMpressed first, and then start the motor to rotate the distillation flask. At the end, it should be shut down first, and then air through to prevent the distillation flask from falling off in the rotation. As a heat source for distillation, it is often equipped with a corresponding constant temperature water tank.
Glass reactor mainly uses its double layer of glass characteristics, we can place the reaction material in the middle of the sandwich, through the atmospheric pressure or negative pressure under the condition of stirring reaction. In this way, the medium inside the interlayer of the glass reactor (such as freezing liquid, heating water or heating oil) can be heated or cooled by stirring in a circular reaction. It is widely used as an ideal equipment in modern biochemical new material synthesis experiments
Environmental protection and energy conservation have become the top priority of building materials
Recently, the State Council issued the "Twelfth Five-Year Plan for Energy Conservation and Emission Reduction", which proposes specific aspects from the overall requirements and main objectives of energy conservation and emission reduction, the responsibility of strengthening energy conservation and emission reduction targets, and the adjustment and optimization of industrial structure. Claim. At the same time, the State Council also announced a number of annexes on energy conservation targets and total chemical oxygen demand emission control plans for the 12th Five-Year Plan. Energy conservation, emission reduction and environmental protection have become the top priority of industrial upgrading and economic restructuring. The work plan clarifies the goal of energy conservation and emission reduction in the next five years, and requires that the energy consumption per unit of GDP, chemical oxygen demand, sulfur dioxide, ammonia nitrogen and nitrogen oxide emissions be higher than during the 11th Five-Year Plan period. Decreased significantly. This has increased the market's confidence in energy saving and emission reduction, and at the same time, it provides a large and stable market demand for related industries. The work plan focuses on six areas of industrial energy conservation, transportation energy conservation, building energy conservation, agricultural and rural energy conservation and emission reduction, commercial and civil energy conservation, and public institutions energy conservation and emission reduction. According to industry analysts, among the six major emission reduction directions, the most promising development prospects and possible greater policy support are in the field of building energy conservation. Building energy conservation is mainly divided into building materials demand outside the building and core technologies and products within the building. In particular, the selection and use of building materials directly affects the country's total carbon emissions. The building materials industry is an important raw material industry, and it is also one of the industries with the most resources reduction, reuse, recycling and potential. Compared with traditional building materials, the manufacture of new building materials can not only reduce the consumption of natural resources and energy consumption, but also enable the rational development and utilization of a large amount of waste. The production of new building materials can not only use production technology that does not pollute the environment, but also can be used as a renewable resource after the product has finished its service life, and will not form new waste foreign matter. The 12th Five-Year Science and Technology Development Plan of the Building Materials Industry issued by the China Building Materials Federation pointed out that building energy conservation and green building have become major demands for national sustainable development. In recent years, new building materials including new waterproof sealing materials, new wall materials, thermal insulation materials and new architectural decoration materials have achieved rapid development. As the materials and technologies used in energy-efficient buildings mature, the market space for new building materials is also growing. At present, large-scale real estate developers are paying more and more attention to the provision and use of green building materials, and the market is in short supply. In addition, with the deepening of new rural construction, new building materials have found a wide market in rural areas. According to statistics, at present, China's rural civil construction area accounts for more than 60% of the country's total construction area. Since the building materials used in the rural market are mostly low-end and mid-range products, the building consumes more energy and has poor environmental protection. This means that new building materials have a very broad space for promotion in rural areas. Rural areas are not only a potential market for new building materials, but also an important source of raw materials for new building materials. Taking straw as an example, the traditional practice is to return to the field by burning, which is easy to cause environmental pollution and low resource utilization efficiency. A group of new building materials enterprises represented by Anhui Chuanshu Building Materials transformed them into building materials such as “straw tiles†and realized the comprehensive utilization of resources. Ji Kunsen, president of the Anhui Provincial Circular Economy Research Association, said that in the past, straw was used as biomass energy, mainly in direct combustion and pyrolysis gasification. Direct-fired type is the direct combustion of crop straw to generate heat, low thermal efficiency and large investment; pyrolysis gasification type will produce a variety of organic compounds and tar, if not recycled, resulting in environmental pollution. Similar to the practice of tree-building materials, the series of development and deep processing of processed by-products have more benefits than the main products, and also meet the circular economy's pursuit of greater economic benefits, less resource consumption, lower environmental pollution and more labor. The basic characteristics of employment. In this regard, Zhang Hua, executive chairman of the China Low Carbon Action Alliance, holds a similar view. He said that in the future, the gathering place of China's wealth will be in the low-carbon field, and the low-carbon road is the only choice for the Chinese economy. Low carbon, as the direction of China's economic transformation, has become the consensus of most people. The transformation must first turn to the idea, and the idea must first turn to thinking. It is the transformation of the thinking of resource consumption into the thinking of resource recycling that has enabled the current high growth of new building materials companies. Compared with economic benefits, social benefits that cannot be ignored are also important reasons for new building materials enterprises to become the mainstream of future development. Wu Jiacheng, vice chairman of the China Soong Ching Ling International Foundation, clearly pointed out that the contribution of Chuanshu Building Materials to the low-carbon economy was first and foremost to contribute to improving the living environment of mankind. In particular, it has taken a step forward in solving the problems of production, life and employment of some farmers. In this process, real enterprise value is realized. The next 20 years will still be a period of high growth in China's economy. It is estimated that by 2020, China will build 30 billion square meters of buildings. As a strategic focus of the building materials industry to adjust its industrial structure and transform its economic growth mode, new building materials have broad prospects for development. Environmental protection and energy conservation are important development directions for new building materials, and the characteristics of “value highland†will be further highlighted. Many “trees and trees†will surely have a brighter future.
