Benzene, 1,1-[(dimethylsilylene)bis(oxy)]bis- - Introduction
dimethyldiphenoxysilane, chemical formula C14H18O2Si, is an organic silicon compound. It has the following properties:
1. Appearance: colorless liquid.
2. Solubility: soluble in organic solvents, such as ethanol, chloroform and ether, slightly soluble in water.
3. Stability: stable at room temperature, not easy to decompose.
4. Smell: with a special aromatic smell.
dimethyldiphenoxysilane has many uses in practical applications, including:
1. Silicone rubber: As a crosslinking accelerator, it can be used in the preparation of silicone rubber.
2. Coatings and adhesives: can be used as additives for coatings and adhesives to provide wear resistance, corrosion resistance and weather resistance.
3. Plastics: used in the production of modified plastics to improve the mechanical properties and heat resistance of plastics.
4. Surface treatment agent: It can be used as a glass surface treatment agent to provide anti-pollution and water resistance.
in terms of preparation method, the common preparation method of dimethyldiphenoxysilane is obtained by reacting dimethyldichlorosilane (chemical formula is C2H6Cl2Si) with phenol. The reaction materials are reacted under suitable conditions to produce the desired product.
In terms of safety information, dimethyldiphenoxysilane has low toxicity. However, it is a flammable liquid and may cause combustion or explosion when exposed to an open flame or high temperature. During use, care should be taken to avoid contact with skin and eyes and maintain good ventilation. In case of accidental use or contact, rinse immediately with plenty of water and seek medical help.
