Nature:
-It is a colorless liquid with a pungent odor.
-Soluble in most organic solvents at room temperature, such as ethanol, ether and benzene.
-It is a flammable substance that reacts violently with oxygen in the air to produce toxic gases.
Use:
- diethyl thiodicarbonate is mainly used in organic synthesis as a reagent and intermediate.
-It is often used in esterification, sulfonyl ester synthesis, alkylation reaction and other organic synthesis process.
-In addition, it can also be used as a sulfur chemical reagent.
Preparation Method:
The preparation of-diethyl thiodicarbonate is usually obtained by the reaction of diethyl carbonate with sulfur.
-During the reaction, heat the mixture of diethyl carbonate and sulfur until the reaction product is completely dissolved and a transparent liquid is formed.
Safety Information:
- diethyl thiodicarbonate is a toxic substance that may be harmful to humans and may cause irritation, respiratory problems or poisoning on contact or inhalation.
-When using, avoid contact with skin, eyes and respiratory organs. If there is contact, rinse with water immediately.
-Provide adequate ventilation and use of personal protective equipment such as lab gloves, goggles and protective masks during operation.
-It should be stored in a cool, dry, well-ventilated place, away from fire and flammable materials.
