Introduction

Difurfuryl disulfide (also known as difurfurylsulfur disulfide) is an organic sulfur compound. The following is an introduction to its nature, use, manufacturing method and safety information:

 

Quality:

- A colorless to yellowish liquid in appearance.

- Has a pungent odor.

- Soluble in organic solvents such as alcohols, ethers and hydrocarbons at room temperature.

 

Use:

- Difurfuryl disulfide is widely used as a catalyst for foaming agents, adhesives, and vulcanizing agents.

- It can be used for vulcanization of polyester resin, which is used to increase the heat resistance and strength of polyester resin.

- It can also be used in the rubber industry to vulcanize rubber to increase its strength and heat resistance.

 

Method:

- Difurfuryl disulfide is generally prepared by the reaction of ethanol and sulfur.

- The product can be obtained by heating ethanol and sulfur in the presence of an inert gas and then distilling it.

 

Safety Information:

- Difurfuryl disulfide has a pungent odor and may cause irritation when in contact with the skin, so prolonged contact should be avoided.

- When using or storing, care should be taken to avoid contact with oxidants, acids, and alkalis to prevent dangerous reactions.

- It has low toxicity, but care should still be taken to avoid inhaling its vapors, avoiding consumption and contact with the eyes and mucous membranes.

- Follow good laboratory practice and wear appropriate personal protective equipment such as gloves and goggles when handling difurfuryl disulfide.

- When disposing of waste, it should be disposed of in accordance with local environmental regulations and avoid discharging it into the environment.
