Properties of diethylene glycol monoethyl ether

Diethylene glycol monoethyl ether (Diethylene Glycol Monoethyl Ether, DEGEE) is an important organic chemical product. Its chemical formula is C6H14O3 and its molecular weight is 134.17. DEGEE is a colorless transparent liquid with low odor, soluble in water and a variety of organic solvents, with a high boiling point (about 196°C) and a low freezing point (about -50°C). These physicochemical properties make DEGEE widely applicable in a variety of industrial applications.

The main use of diethylene glycol monoethyl ether

DEGEE has important applications in many fields such as chemical industry, medicine, agriculture and daily chemicals. Its main uses include:

1. Solvent :DEGEE is widely used in paints, coatings, cleaning agents and inks. As an effective solvent, it can enhance the stability and fluidity of these products and improve their application performance.

2. Pharmaceuticals and Cosmetics: In the pharmaceutical industry, DEGEE is used as an excipient in pharmaceutical preparations to improve the solubility and stability of drugs. In cosmetics, DEGEE is widely used in skin care products and hair products as a moisturizer and solvent.

3. AGROCHEMICALS :DEGEE is used as a solvent and dispersant in pesticide formulations to improve the effectiveness and stability of pesticides.

Diethylene glycol monoethyl ether upstream raw material

The production of DEGEE mainly depends on the following upstream raw materials:

1. Ethylene oxide: Ethylene oxide is the key raw material for the synthesis of DEGEE, which is produced by the addition reaction of ethylene oxide and ethylene glycol monoethyl ether under alkali catalysis. Ethylene oxide is an important organic chemical raw material, which is widely used in the production of a variety of ethylene glycol compounds.

2. Ethylene glycol monoethyl ether: Ethylene glycol monoethyl ether is prepared by the acid-catalyzed esterification of ethylene glycol with ethanol. As a precursor of DEGEE, its quality and purity directly affect the quality of DEGEE.

Diethylene glycol monoethyl ether downstream products

DEGEE's downstream products cover multiple industries, including:

1. Coatings and paints :DEGEE is widely used in coatings and paints to improve the gloss, adhesion and weather resistance of products.

2. Cleaning agent: Due to the good solubility of DEGEE, it is used as a high-efficiency solvent in industrial and household cleaning agents, which can effectively remove oil stains and other stubborn stains.

3. Cosmetics: In skin care products and hair care products, DEGEE is used as a moisturizer and solvent to improve the feel and stability of the product.

4. Pharmaceuticals :DEGEE is used as a solvent and excipient in the pharmaceutical industry and is widely used in a variety of pharmaceutical preparations.

Diethylene glycol monoethyl ether storage method

The storage of DEGEE needs to pay attention to the following aspects to ensure its quality and safety:

1. Environmental conditions :DEGEE should be stored in a dry, cool, well-ventilated place, avoid direct sunlight and high temperature environment. The storage temperature should be controlled at room temperature to avoid severe temperature fluctuations.

2. CONTAINER REQUIREMENTS :DEGEE shall be stored in sealed, light-tight containers to prevent volatilization and oxidation. Common storage containers include stainless steel drums, glass bottles, or high-density polyethylene drums.

3. Fire and explosion -proof: Because DEGEE has a certain degree of flammability, it should be away from fire sources, heat sources, and avoid contact with oxidants. The storage area shall be provided with necessary fire fighting equipment such as fire extinguishers and hydrants.

4. Labels and identification: storage containers should be clearly labeled, indicating the name of the substance, purity, production date and expiration date and other information, in order to facilitate management and use.

Diethylene Glycol Monoethyl Ether Market Prospects

With the increasing demand for industrial and daily consumer goods, the market demand for DEGEE is also steadily increasing. Especially in high value-added industries such as coatings, pharmaceuticals and cosmetics, DEGEE has a good market prospect due to its unique performance and wide applicability. With the increasingly stringent environmental regulations, DEGEE, as a low toxicity and low volatility solvent, is gradually replacing traditional organic solvents, and has great market potential.

Environmental and safety considerations

Although DEGEE is relatively safe, it is still necessary to pay attention to environmental protection and safety issues during its production and use. DEGEE's waste and wastewater treatment must comply with local environmental regulations to avoid environmental pollution. Operators should wear appropriate personal protective equipment, such as gloves, protective glasses and protective clothing, when handling DEGEE to prevent skin contact and inhalation of vapors.

Conclusion

As an important chemical raw material, diethylene glycol monoethyl ether has a wide range of applications and market prospects. Its excellent solubility, stability and relatively low toxicity make it an indispensable component in many industries. In the future, with the progress of science and technology and the improvement of environmental protection requirements, the application of DEGEE will be more extensive, and its market will continue to grow. Therefore, in-depth understanding of its nature, use, upstream and downstream raw materials and storage methods is of great significance to promote the development of related industries.
