Chemical Property of Sulfolane
Sulfolane is a colorless and tasteless soild at room temperature, melted at 27.8℃.The most industrial products are colourless and light yellow liquid. Sulfolane has high solubility property and selectivity.Sulfolane is solubled in water with arbitrary ratio,also solubled in aromatics and alcohol easily,but solubled in paraffin and olefin hydrcarbon little.Sulfolane has high stability with hot acid and alkali.It doen’s react with acid,alkali, sulfur,alcohol at room temperature,also doen’s decompose and polymerize.When the temperature is higher than 240℃, the sulfolane will decompose SO2.Sulfolane has stable chemical property,it will not appear polyreaction and decomposition under common condition with the existence of acid and alkali.

3.Applications of sulfolane
Sulfolane has high dissoplving property and selectivity,so it is suitable for petrochemical industry.It is widely used as excellent solvent for aromatic extraction and removing sulphur from natural gas.Sulfolane is a multi-effective solvent with high purity and high boiling point,so it is suitable for chemical industry .This solvent can be used for the halogenate,methylization,organic synthesis,condensation and polymerization reaction in the field of pharmaceutical chemicals,agricltural chemicals,dyestuff,perfume,special industrial plastic and some other chemicals.
4.Safety property of sulfolane
This products is a material with low poison.Poisonousness going acutely through the mouth of a big mouse is:LD50>1900mg/kg.According to the International Ocean Shiping Dangerous Cargo Regulation,Sulfolane is not dangerous commodity and there is not pollution to ocean,so it can be transported as common commodity.
5.Package and tranportaion
The package is 200L new galvanized drum.The net weight of sulfolane filled in one drum is 250KG,we fill nitrogen before closing the package.
It can be transported by automobile,container or ISO tank.
