Product Name: Petrobenzene  
Trade Mark: Sanren Brand  
Alternative Name: ?  
Molecular formula/Structural Formula:
Production Process: Using hydrofined pyrolysis gasoline or catalytic reformate as raw material, the product is obtained through the process of sulfolane extraction and aromatics rectification.  
Properties: Petrobenzene is one of the aromatic hydrocarbons. It is colourless and transparent, volatile, inflammable and toxic with acromatic smell. It is not soluble in water but in organic solvents such as ethanol, ether, chloroform. Its vapor and air could form an explosive mixture with the explosion limits between 1.4 ~ 8.0 Vol.%, boiling point 80.1℃, flash point -11℃ and ignition point 560℃.

Safety Precautions: 1. Petrobenzene is an inflammable gas and must be kept away from fire, heat sources and avoid direct sunlight.
2. In accordance with the relevant Government Ordinance concerning hazardous chemicals, due formalities must be gone through for the permission of transportation. Static electricity discharger must be provided to prevent static electricity from being accumulated. Fire fighting devices must be equipped as well.
3. Guard against leakage and handle in closed condition.
4. Petrobenzene is toxic. Its vapor with a high concentration is anesthetic. Repeated inhalaion of low concentration benzene vapor can result in chronic poisoning. It irritates eyes, skin and upper respiratory tract. While handling, labour protection articles must be provided. Safety education should be conducted for those involved in handling.
