3. Molecular weight: 185.37g/mol.
4. Boiling point: 58-59 ℃.
5. melting point:-109 ℃.
6. Density: 0.808 g/mL.
The main uses of tert-butyl cyanodimethylsilane include:
1. additives: can be used as polymer modifier and lubricant.
2. controlled release agent: used to prepare sustained release system, such as rubber, plastic and coating.
3. catalyst: can be used as metal catalyst and catalyst carrier.
4. waterproof agent: can be used for building materials, textiles and leather waterproof processing.
5. silicone rubber: can be used for synthetic silicone rubber.
tert-Butylcyanodimethylsilane can be synthesized by the following methods:
Sodium cyanide and tert-butyl chlorosilane are reacted in acetone, and then dimethylamino chloride is added, which is prepared by hydrolysis, separation and purification.
Regarding safety information, tert-butylcyanodimethylsilane is an organosilicon compound and has low toxicity under general conditions. But still need to pay attention to the following safety operations:
1. avoid inhalation of gas, mist, steam and dust.
2. Avoid contact with skin and eyes. In case of contact, rinse immediately with plenty of water.
3. Wear appropriate personal protective equipment such as protective gloves, goggles and protective clothing during operation.
4. Do not put the substance in direct contact with strong oxidants to avoid dangerous reactions.
5. storage should be sealed centralized storage, away from fire and heat sources.
Before using tert-butyl cyanodimethylsilane, it is recommended to read and understand relevant safety materials, and strictly follow the operating procedures for safe operation. In case of special circumstances or accidents, please seek professional guidance or corresponding first aid treatment.
