Introduction
Isoprene mercaptan is an organic compound. Its properties are as follows:
It can be dissolved in many organic solvents such as alcohols, ethers, and hydrocarbons.
2. Chemical properties: Isoprepent mercaptan is a highly reducing compound that can react with oxygen to form sulfur dioxide. It can also be oxidized by chlorine to isovaleric acid, or oxidized by oxidants to sulfuric acid. Isopentol also has the property of an addition reaction with other compounds.
Applications of isoprene mercaptan:
1. Chemical reagents: Isopentanol is a commonly used reducing agent and sulfiding agent, which is widely used in organic synthesis and analytical chemistry.
2. Odor masking agent: its strong pungent odor, isoprel mercaptan is often used as a chemical to mask other foul odors, such as adding a certain amount of isoprene mercaptan to natural gas to mask the odor.
There are several main methods for preparing isopreamyl mercaptan:
1. Produced from vinyl alcohol: vinyl alcohol is heated with sulfur to produce isopentanol.
2. Preparation from 15%-alcohol solution: high-purity isoprem mercaptan can be obtained by distilling, concentrating and distilling the alcohol solution and hydrogen sulfide.
The following safety information should be taken into account when using isopentanol:
1. Isopentan mercaptan has a strong pungent odor and should avoid direct contact with the skin, eyes, and respiratory tract. Wear appropriate personal protective equipment such as gloves, glasses, and protective masks when using.
2. Isopentol has a low flash point and flammability, and should be kept away from ignition and high temperatures. Avoid contact with open flames or other combustibles.
3. Isopentan mercaptan is a substance that is harmful to the environment and has poor biodegradability, and should not be discharged into the natural environment at will, and should be treated and disposed of in accordance with relevant regulations.
