Ethylene glycol butyl ether properties
Ethylene glycol butyl ether (Ethylene Glycol Butyl Ether, abbreviated EGBE), also known as 2-butoxyethanol, is a colorless, transparent liquid with a slight ether fragrance. It has a chemical formula of C6H14O2, a molecular weight of 118.17g/mol, a boiling point of 171°C, a density of 0.9g/cm³, and a flash point of 61°C. It has good solubility and can dissolve a variety of polar and non-polar compounds, such as oils, resins, dyes and a variety of organic solvents. These properties make ethylene glycol butyl ether an ideal solvent for many industrial applications.
Ethylene glycol butyl ether use
Glycol butyl ether is widely used in many industrial fields. It is a commonly used solvent, especially important in the paint and coatings industry, for the deployment of latex paint, baking paint, spray paint and other water-based coatings, can improve the uniformity and adhesion of the coating. In the detergent industry, ethylene glycol butyl ether is a highly effective surfactant used in the manufacture of various industrial and household cleaners. Third, ethylene glycol butyl ether is also used in inks, dyes and pesticides as dispersants and dissolving agents to improve product stability and performance. In cosmetics and personal care products, ethylene glycol butyl ether is also used as a solvent and moisturizer to enhance the texture and efficacy of products.
Glycol butyl ether upstream feedstock
The production of ethylene glycol butyl ether mainly depends on two upstream feedstocks: ethylene glycol and n-butanol. Ethylene glycol is an important organic chemical raw material, which is produced by the oxidation and hydration of ethylene, which comes from petroleum cracking or natural gas. n-Butanol is also an important organic solvent, usually obtained by hydrogenation of butenes obtained from petroleum cracking. These two raw materials undergo an etherification reaction to form ethylene glycol butyl ether. The supply and price fluctuations of raw materials directly affect the production cost and market price of ethylene glycol butyl ether.
Glycol butyl ether downstream products
As an intermediate and solvent, ethylene glycol butyl ether is widely used in many industries, and its downstream products are various. In the coating industry, ethylene glycol butyl ether is used to manufacture a variety of latex paint, acrylic paint and polyurethane paint, etc., used in construction, automotive, home appliances and other fields. In the detergent industry, downstream products include industrial degreasers, metal cleaners and household multifunctional cleaners. In the field of agrochemical, ethylene glycol butyl ether is used as a solvent and adjuvant for pesticides to improve the dispersion and effectiveness of pesticides. In the cosmetics industry, ethylene glycol butyl ether is used in the manufacture of perfumes, lotions, facial cleansers and other products to improve their texture and feel of use.
Ethylene glycol butyl ether production process
Ethylene glycol butyl ether is usually produced by etherification reaction process. Ethylene glycol and n-butanol are mixed in a certain proportion, and an appropriate amount of catalyst, such as sulfuric acid or phosphoric acid, is added to carry out the etherification reaction. The reaction is carried out at high temperature (about 150-200°C) and high pressure (about 0.5-1.0 MPa) to produce ethylene glycol butyl ether and water. Then, ethylene glycol butyl ether is separated by distillation, and unreacted raw materials and by-products are removed to obtain pure ethylene glycol butyl ether product. The process has the advantages of simple operation, low cost and high product purity, and is widely used in industry at present.
Ethylene glycol butyl ether storage method
Ethylene glycol butyl ether has a certain degree of volatility and flammability, so its storage needs to take appropriate safety measures. Glycol butyl ether should be stored in a cool, ventilated and dry warehouse, away from fire, heat and oxidant. The storage container shall be closed metal drum or glass steel tank to prevent leakage and volatilization. Again, the warehouse should be equipped with fire fighting equipment, such as dry powder fire extinguishers, foam fire extinguishers, etc., just in case. Operators should wear protective gloves and goggles to avoid skin contact and eye irritation when handling and using glycol butyl ether. According to the above storage method, it is possible to ensure the safe storage of ethylene glycol butyl ether and prevent the occurrence of accidents.
Ethylene Glycol Butyl Ether Market Prospects
With the acceleration of industrialization and urbanization, the demand for ethylene glycol butyl ether is increasing year by year. Especially in the paint, detergent and pesticide industries, its application is widespread and irreplaceable. In the future, with the enhancement of environmental awareness and strict regulations, the demand for low toxicity and low volatility solvents will increase. As an environmentally friendly solvent, ethylene glycol butyl ether has a broad market prospect. Technological advances and improvements in production processes will also reduce production costs, improve product quality, and further promote the development of the ethylene glycol butyl ether market.
Summary
Ethylene glycol butyl ether is a chemical product with excellent performance and wide application. Its unique chemical properties and good solubility make it occupy an important position in the industries of coatings, detergents, pesticides and cosmetics. By analyzing the properties, uses, upstream raw materials, downstream products, production processes and storage methods of ethylene glycol butyl ether, we can see its importance in modern industry and broad market prospects. In the future, with the progress of science and technology and the change of market demand, ethylene glycol butyl ether will continue to play its important role and provide important support for the development of various industries.
