Ethylene glycol tert-butyl ether (ETB) is an organic compound widely used in the field of chemical raw materials. This article will introduce the properties, uses and production methods of ethylene glycol tert-butyl ether in detail.
1. the properties of ethylene glycol tert-butyl ether
ethylene glycol tert-butyl ether is a colorless and transparent liquid with a light and elegant odor. Its molecular formula is C6H14O2 and its molecular weight is 118.17. The boiling point of ethylene glycol tert-butyl ether is 126~128 ℃, the flash point is 21.7 ℃, the density is 0.87g/cm3, the refractive index is 1.4007, and the viscosity is 2.1mPa · s. In addition, it also has good solubility and chemical stability, and can be miscible with water, alcohol, ether and other solvents.
2. the use of ethylene glycol tert-butyl ether
ethylene glycol tert-butyl ether in the field of chemical production raw materials has a wide range of uses, the following list of several major applications:
1. solvent: ethylene glycol tert-butyl ether is an excellent solvent, can be used in the production of coatings, inks, adhesives and other products. Because of its good solubility and chemical stability, ethylene glycol tert-butyl ether has high application value in these fields.
2. Fuel additives: Ethylene glycol tert-butyl ether can be used as fuel additives to improve the combustion performance and anti-knock performance of fuel. At the same time, it can also reduce the surface tension of the fuel, improve the atomization performance of the fuel, and improve the combustion efficiency.
3. Chemical intermediates: Ethylene glycol tert-butyl ether can be used as chemical intermediates for the production of other chemicals, such as ethylene glycol, tert-butyl alcohol, etc.
3. ethylene glycol tert-butyl ether production method
ethylene glycol tert-butyl ether production method mainly has two kinds of ester exchange method and alcohol etherification method. Among them, in the transesterification method, ethylene glycol and tert-butanol are used as raw materials, and a transesterification reaction is carried out in the presence of an acidic catalyst to produce ethylene glycol tert-butyl ether and water. Alcohol etherification law is based on ethylene oxide and tert-butyl alcohol as raw materials, in the role of alkaline catalyst for the addition reaction, the formation of ethylene glycol tert-butyl ether. These two methods have their own advantages and disadvantages, and the appropriate production method can be selected according to the actual production needs.
In conclusion, as an important raw material for chemical production, ethylene glycol tert-butyl ether has broad application prospects. Through the in-depth understanding of the nature and use of ethylene glycol tert-butyl ether, we can better play its role in the chemical industry and promote the sustainable development of the chemical industry.
