Petroleum toluene (CAS 108-88-3) is a colorless, water-insoluble aromatic solvent derived from petroleum refining, with the chemical formula C7H8. It is primarily used as an industrial solvent, a chemical intermediate for benzene and xylene production, and a gasoline additive.

What is Petroleum Toluene?
Petroleum toluene is an aromatic hydrocarbon recovered from petroleum refining and catalytic reforming processes. Petroleum toluene has the molecular formula C7H8 and a molecular weight of 92.14 g/mol. Petroleum toluene is a colorless, transparent liquid with a distinctive aromatic odor. Petroleum toluene is insoluble in water but miscible with most organic solvents, including ethanol, ether, and acetone.

 

 

Industrial Applications of Petroleum Toluene

 

Petroleum toluene is widely used as an industrial solvent in paints, coatings, adhesives, and inks. Petroleum toluene also serves as a chemical intermediate in the production of benzene, xylene, and toluene diisocyanate (TDI) for polyurethane manufacturing.

 

Petroleum toluene is commonly blended into gasoline to increase octane rating and improve combustion performance. This application accounts for a significant share of global toluene consumption.

 

It is used as a solvent in select pharmaceutical intermediate synthesis and in the fragrance industry, including nail polish and cosmetic formulations. Petroleum toluene is preferred over benzene in these applications because toluene carries a lower toxicity classification and less restrictive exposure limits under most industrial safety regulations.

What is the CAS number of petroleum toluene?
The CAS number of petroleum toluene is 108-88-3.

 

What payment terms do you accept for toluene orders?
Standard payment terms require a deposit before production, with the balance settled against the bill of lading copy. L/C at sight is also accepted for verified buyers.

 

Do you provide a Certificate of Analysis (COA) with each shipment?
Yes, every batch of petroleum toluene is tested by gas chromatography before shipment, and a COA is provided along with the SDS and packing list.

 

How is petroleum toluene different from petroleum benzene?
Petroleum toluene and petroleum benzene are both aromatic solvents with similar solvency properties, but toluene carries a lower toxicity classification than benzene, which is a known carcinogen. As a result, toluene is more widely used in applications such as pharmaceuticals and fragrances, where benzene use is heavily restricted.
