3-Mercapto-2-propanol - Introduction
Nature:
1-MERCAPTO-2-PROPANOL is a colorless to light yellow liquid with a weak sulfur odor. It is soluble in water and common organic solvents such as alcohols and ethers. It gradually oxidizes in the air and may turn yellow when exposed to light.
Use:
1-MERCAPTO-2-PROPANOL has a wide range of applications in the chemical industry. It is an effective reducing agent and chelating agent, and is often used in organic synthesis to reduce functional groups such as aldehydes, ketones, acids and sulfates. In addition, it can also be used as an antioxidant, preservative and acidic catalyst.
Method:
1-MERCAPTO-2-PROPANOL may be prepared by thiolation of 2-propanone. The specific preparation method includes the reaction of thionyl chloride (SOCl2) with acetone, followed by hydrolysis to obtain the product.
Safety Information:
1-MERCAPTO-2-PROPANOL is irritating and should avoid inhalation or contact with skin and eyes. Wear protective gloves, goggles and other personal protective equipment during use. If accidentally contact, should immediately rinse with plenty of water, and timely medical treatment. In addition, it is also a flammable liquid and should be kept away from fire and high temperature. When storing and handling, observe the relevant safety practices.
