Bis(2-5-Dimethyl-3-furyl)disulfide（CAS#28588-73-0）

Introduction

3,3′-Dithiobis(2,5-dimethyl)furan, also known as DMTD, is an organosulfur compound. The following is an introduction to some of its properties, uses, manufacturing methods, and safety information:

Quality:

- Appearance: DMTD is a colorless to light yellow liquid with a special thioether odor.

- Solubility: DMTD is insoluble in water and soluble in organic solvents such as alcohols, ethers, and hydrocarbons.

Use:

- DMTD is used as a vulcanization accelerator and preservative. It can be used in the rubber industry to promote the vulcanization reaction of rubber and improve the strength, wear resistance and aging resistance of rubber products.

Method:

- DMTD can be prepared by the reaction of dimethyl disulfide (DMDS) with dimethylfuran. The reaction takes place at high temperatures (150-160 °C) and undergoes distillation and other processing steps to obtain a pure product.

Safety Information:

- DMTD has a pungent odor and should be avoided for prolonged exposure.

- In industrial production environments, proper ventilation and personal protective measures such as gloves, goggles, and protective clothing must be in place.

- DMTD is irritating to the skin and eyes, so avoid contact with it.

- When storing and using, keep away from high temperatures, open flames, and oxidizing agents.
