Paint and varnish industry
Toluene (or methylbenzene) is a liquid and transparent substance with a strong odor, compatible with most alcohols, ether compounds and hydrocarbons. We offer to buy toluene in bulk, with a basic substance content of at least 99.75%.
The composition has been known since 1835, when it was obtained from the distillation of pine resin. Then people began to produce it from tolu balsam, which is taken from the Miroxilon tree. Today the substance is obtained from petroleum gasoline fractions. A complex separation process is performed: catalytic reforming, selective extraction and rectification. As a result, a substance with a high degree of purity is formed.
If you need to order a batch of petroleum toluene, you can buy a slightly different composition. Sometimes benzene is used for its production. The production technology is different: the method of alkylation with the addition of acid-based catalysts is used. The quality of the product and the degree of purity are approximately the same in both versions.
Application of petroleum toluene
The product is suitable for creating nitrotoluenes, benzene, benzoic acid. It dissolves polymer compounds well and is used to dilute paints and varnishes. It is also used for chemical synthesis and acts as an integral part of fuel mixtures. The substance is also added to solvents that are used to dilute vinyl, acrylic, epoxy compounds.
The price of petroleum toluene depends on the volume of purchase and the region of delivery. Delivery is carried out by rail, sea or road transport in tanks.
