Product Description

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.

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.
