18246-65-6 - Introduction
(HMDS, chemical formula: C6H18OSi), also known as trimethyl silicon hydroxide compound, is an organic silicon compound. The following is a description of its nature, use, preparation and safety information:
Nature:
1. Appearance: colorless transparent liquid.
2. Boiling point: up to about 125 ° C.
3. Density: about 0.79 g/cm.
4. Solubility: Soluble in organic solvents, insoluble in water.
Use:
1. Surfactant: HMDS has the characteristics of reducing surface tension and increasing wettability, and is commonly used as a surfactant for coatings, inks, adhesives, etc.
2. Moisture-proof agent: because HMDS has a low surface tension, it can be used as a moisture-proof agent, which is often used in the manufacturing process of optical components or electronic components.
3. Organic Synthesis: HMDS is often used as a catalyst for organic synthesis reactions, such as hydrogenation reaction, Nitro reaction, alkylation reaction, etc.
Method:
It can be prepared by silanization. A common preparation method is to react chlorosilane with ethanol to obtain hydroxysilane, and then react hydroxysilane with pentanediol, generate.
Safety Information:
1. HMDS should be kept away from fire and high temperature and stored in a cool, well-ventilated place. When using, avoid direct contact with skin, eyes and respiratory tract, and wear appropriate protective equipment, such as gloves, goggles and masks.
3. In case of accidental contact, rinse immediately with plenty of warm water and seek medical help.
4. In the process of handling and storage, should comply with the relevant safety procedures.
