22128-43-4 - Introduction
4-Methyl-1-octyn-4-ol is an organic compound with the chemical formula C9H16O. The following is a description of its nature, use, preparation and safety information:
Nature:
4-Methyl-1-octyn-4-ol is a colorless to pale yellow liquid with a special fragrance. It is soluble in water and is compatible with many organic solvents such as alcohols, ethers and esters.
Use:
4-Methyl-1-octyn-4-ol is commonly used in the fragrance and fragrance industry. It has a unique aroma, commonly used in the deployment of peach, apple, grape and other fruit aroma. In addition, it can also be used to synthesize other compounds, such as drugs, dyes and plastic additives.
Preparation Method:
The preparation of 4-Methyl-1-octyn-4-ol is generally obtained by reacting acetylene with 4-methyl-1-octene. First, 4-methyl-1-octene is subjected to hydrogenation reaction using hydrochloric acid or hydroacetic acid as a catalyst under appropriate conditions to obtain 4-methyl-1-octenol. 4-Methyl-1-octenol is then cyclized to give 4-Methyl-1-octyn-4-ol.
Safety Information:
4-Methyl-1-octyn-4-ol is irritating and contact with skin and eyes may cause inflammation. Appropriate safety precautions should be taken during operation, such as wearing protective glasses, gloves and protective clothing. At the same time, to avoid inhaling its vapor, it should be used in a well-ventilated place. During use and storage, the relevant safe operation guidelines should be observed, and it should be kept away from ignition and flammable materials. Such as accidental contact or inhalation, should immediately wash or medical treatment.
