Preparation method of alkyne cyclohexanol:
There are several ways to prepare alkynyl cyclohexanol, and the commonly used ones include:
- Isobutylene is used as a raw material, hydrogenated under acidic conditions to produce isobutenol, and then through alkali catalysis, a rearrangement reaction occurs to obtain alkyne cyclohexanol.
- Hydrogen pressurized reaction: cyclohexene and hydrogen react in the presence of a catalyst to form alkyne cyclohexanol.
Safety information for alkynocyclohexanol:
- Cyclohexanol is irritating and may cause irritation and redness when it comes into contact with the skin and eyes.
- May cause allergic reactions, take personal protection when using it.
- During operation, inhalation of its vapors and dust should be avoided to avoid irritation to the respiratory tract.
- When storing, it should be stored tightly sealed, in a cool, dry place, away from fire and high temperatures.
