Diethoxymethylsilane: Properties, Applications and Manufacturing
Diethoxymethylsilane (DEMS) is a colorless, transparent liquid that is soluble in organic solvents like ethanol, toluene, and acetone. It has a pleasant odor and a molecular weight of 118.22 g/mol. DEMS is a member of the organosilicon compound family, which contains silicon atoms bonded to carbon atoms by covalent bonds. It is widely used in various industries due to its excellent properties, such as hydrophobicity, adhesion, and reactivity with other compounds.
Manufacturing of Diethoxymethylsilane
INNO Specialty Chemicals is a leading manufacturer and supplier of DEMS from China. The company produces DEMS by reacting methyl chloride with silicon tetrachloride in the presence of anhydrous aluminum chloride. The resulting methyltrichlorosilane is then treated with ethanol in the presence of a catalyst like hydrochloric acid to yield DEMS.
Properties of Diethoxymethylsilane
DEMS has several physical and chemical properties that make it useful in various applications. One of its most notable features is its ability to form stable bonds with other materials, such as metals, glass, and plastics. This makes it an ideal adhesive for use in the electronics industry, where it is used to bond silicon wafers, chips, and other components.
DEMS is also highly reactive with water, which makes it useful in waterproofing and moisture-resistant coatings. Additionally, it is an effective surface modifier, changing the surface properties of materials to improve their performance in specific applications.
Applications of Diethoxymethylsilane
DEMS finds extensive use in several industries, including electronics, aerospace, automotive, and construction. Some of its applications are:
1. Adhesives and Sealants: DEMS is an excellent adhesive and sealant, particularly for bonding silicon wafers and chips in the electronics industry. It is also used as a sealant in building construction to prevent water leakage.
2. Coatings: DEMS is used in the production of water-resistant coatings for buildings, automobiles, and aircraft. It is also used to coat glass surfaces to improve their scratch resistance and durability.
3. Surface Modification: DEMS is used to modify the surface properties of materials to improve their performance in specific applications. For example, it is used to improve the hydrophobicity of textiles, paper, and wood.
4. Chemical Intermediates: DEMS is used as a precursor for several other organosilicon compounds, such as methyltriethoxysilane and ethyltrimethoxysilane.
Safety and Handling of Diethoxymethylsilane
DEMS is a flammable liquid and should be stored and handled with care. It should be stored in a cool, dry place away from heat, sparks, and flames. It is also important to wear protective gear, such as gloves, goggles, and a respirator, when handling DEMS.
Conclusion
Diethoxymethylsilane is a versatile organosilicon compound that finds extensive use in various industries due to its excellent properties, such as adhesion, waterproofing, and surface modification. INNO Specialty Chemicals is a leading manufacturer and supplier of DEMS from China, ensuring a reliable supply of this critical material. As with all chemicals, it is important to follow proper handling and safety procedures when working with DEMS.
