Petrobras produces several types of solvents for varied applications. They are classified in two categories: aliphatic and aromatic solvents.
Aliphatic Solvents
Aliphatic solvents are those in which there is a predominance of paraffinic hydrocarbons coming from the fractioning of naphthas and kerosenes that originate from oil distillation. The following are among the aliphatic solvents:
- Turpentine: constituted of flammable, low-speed organic compounds, with low volatility and high solvency power, obtained from the processing of intermediary oil fractions. This solvent is used in several industrial segments, such as: paint, varnish, general cleaning, wax, resin, grease, print, and dry wash, polish, and herbicide industries.
- Paint diluent: composed of flammable organic compounds obtained from the fractioning of naphthas and purified through the molecular sieve process to eliminate the benzene. This solvent is used in the adhesive, varnish, protecting coatings, and paint industries.
- Hydrogenated fluids: these solvents were developed to attend to increasingly strict environmental and legal regulations. The hydrogenated fluids form a line of ecological solvents produced from the fractioning and hydrogenation of intermediary oil fractions. Hydrogenated fluids are used in the paint, resin, and dry wash industries, to formulate domestic products, aerosols, copying machines, general cleaning products, cold lamination and in agrochemistry.
- Hexane: Formed by flammable organic compounds, volatile and with high solvency power, hexane is obtained from the fractioning of naphtha and later purification to eliminate the benzene. This solvent is used in the vegetable oil extraction industries, and to manufacture glues, adhesives, and in rubber and lamination products.
- Medium solvent: Formed by low volatility flammable organic compounds with high solvency power. The medium solvent is produced from the processing of intermediary oil fractions. It is applied in several industrial segments, such as in the manufacturing of paints, waxes and to clean machines.
- Rubber solvent: composed of flammable organic compounds obtained from the fractioning of naphthas and purified through the molecular sieve process or hydrogenation to eliminate the benzene. This solvent is used in the adhesive and rubber artifact industries.
Aromatic Solvents
Aromatic solvents are polar solvents derived from naphtha processing in Catalytic Reform and Aromatic Recover units. They are obtained as chemically pure or mixed products. The following are among the aromatic solvents:
- Toluene: highly pure solvent with high solvency power and low volatile content. This solvent is used in the paint, varnish, adhesive, rubber, cutting oil, resin and printing industries.
- Xylene: composed of a mix of isomers. This solvent has high solvency power and low volatile content. It is used in the paint, glue and adhesive, rubber, dye, resin, varnish, metallurgy, pesticide, and electro-electronic industries.
