Solubility: Insoluble in water, easily soluble in most organic solvents.
Isobutylene is an olefin compound with a carbon number of 4.
Nature:
1. Isobutylene is a colorless liquid with a special odor.
2. It is easy to react with air and can self-polymerization.
3. Isobutene is soluble in organic solvents such as ethanol, acetone and benzene, and insoluble in water.
Purpose:
Isobutylene is an important chemical raw material, mainly used in the preparation of butyl rubber, polyisobutylene, methacrylonitrile, antioxidant, tert-butylphenol, tert-butylether and so on.
1. Isobutylene is irritating and has an irritating effect on the skin, eyes and respiratory tract. Wear appropriate protective equipment during operation.
2. Isobutylene is a flammable liquid that will deflagrate in case of open fire, high temperature or open flame. Keep away from open flames and heat sources, store tightly and avoid contact with oxidants.
3. Places where isobutylene is used and stored should be well ventilated to avoid steam accumulation.
4. Isobutylene has certain harm to the environment, and measures should be taken immediately when the harmful substances overflow.
