Bis-2-methyl-3-furyl-disulfide（CAS#28588-75-2）

Introduction

Bis(2-methyl-3-furanyl)disulfide, also known as DMDS, is an organic sulfur compound. The following is an introduction to its nature, use, preparation method and safety information:

Quality:

- DMDS is a colorless to pale yellow liquid with a strong sulfur taste.

- It is volatile and can quickly evaporate into toxic gases.

- DMDS is soluble in alcohols, ethers and most organic solvents, and insoluble in water.

Use:

- DMDS is widely used in different fields, including fuel additives, rubber additives, dyes, catalysts in organic synthesis, etc.

- It can be used as a vulcanizing agent in the petroleum industry for processing heavy oil and coal-to-natural gas, etc.

- DMDS can also be used in the manufacture of fungicides, pesticides and vinyl acetate compounds.

Method:

- DMDS is usually prepared by the reaction of dimethyl disulfide with chlorofuran. This reaction is usually catalyzed by aluminum tetrachloride.

Safety Information:

- DMDS is a toxic substance, and inhalation of high concentrations of the gas can cause irritation and harm to the human body.

- Wear protective gloves, goggles, and gown when handling DMDS.

- Avoid contact with the skin and take care to avoid inhaling its gases.

- When using DMDS, ensure good ventilation and try to avoid leakage into the environment.

- High concentrations of DMDS gas may cause irritation of the eyes and respiratory tract, if you do not feel comfortable, seek medical attention immediately.
