Chloromethylpentamethyldisiloxane - Introduction

It is an organosilicon compound with the chemical formula CH3Si(OCH3)2Cl, also known as chloromethyl dimethyl methyl silane.

The compound has the following properties:

1. Appearance: colorless liquid or low boiling point solid (depending on temperature);
2. Boiling Point: about 110-120 C;
3. Density: about 0.93-0.96g/cm³;
4. Solubility: Soluble in organic solvents, such as ethanol and chlorinated hydrocarbons.

The main uses of calcium include:

1. As a crosslinking agent for silicone rubber and silicone resin, it can enhance the heat resistance and chemical resistance of the material;
2. Used as chain transfer agent and initiator in organic synthesis;
3. Used as lubricant and surfactant;
4. Used for the preparation of anti-foaming agents, Defoamers and rubber additives.

Method:

can be prepared by adding methyl chloride to monosilane. There are many specific preparation methods, one of the common methods is the reaction of monosilane and methyl chloride under suitable conditions, usually under an inert atmosphere.

Safety Information:

1. It is irritating and can cause irritation and burning when in contact with the skin or eyes. Avoid direct contact with skin and eyes when using this compound, and wear appropriate protective equipment when using it;
2. In the use of the process should pay attention to avoid inhalation of its vapor or spray. If you accidentally inhale a large amount of steam or spray, stop the operation immediately and breathe fresh air in a well-ventilated place;
3. With oxidant, strong acid, strong alkali and other violent reaction, need to pay attention to fire and explosion;
4. Prolonged or large exposure to the substance may cause health hazards, so safe operating procedures should be followed to avoid long-term or large exposure.

Please note that this is only a general overview of the compound. For more detailed safety information and operating advice, refer to the safety data sheet of the compound or consult a professional.
