Detailed explanation of aromatic solvent oil

Aromatic solvent oil is a series of solvents composed of C9 and C10 heavy aromatic isomers. Its main components are trimethylbenzene, tetramethylbenzene and their isomers, usually known as high boiling point aromatic solvent oil. Aromatic solvent oil is one of solvent oils. It is mainly extracted from furfural, FCC slurry, ethylene tar, etc. The by-product light oil obtained by distillation column separation and distillation can be used as plasticizer of PVC. Aromatic solvent oils have excellent solubility, chemical and physical stability, high boiling point, slow volatilization and good leveling property. It can be used as solvent for various coatings. At present, about 30% of the organic solvents in the world are petroleum solvents, among which the aromatic solvent oils with high boiling point above C9 and C9 account for about 14.8%. The boiling points of C9 aromatic hydrocarbons are higher than those of benzene, toluene and xylene, which volatilize slowly and have strong solubility. It has good solubility to synthetic resin. Foreign oil companies produce high boiling point solvent oils from aromatics, a byproduct of ethylene plants, which are widely used in coatings, printing inks, precision machine cleaners and pesticide emulsifiers. The market prospect of high boiling point aromatic solvent oil in China is broad. According to the chemical structure, solvent oil can be divided into alkanes, cycloalkanes and aromatics. According to boiling range, solvent oil can be divided into low boiling point solvent oil, neutral solvent oil and high boiling point solvent oil. Figure 1: s series aromatic solvent oils. As a new solvent developed at the end of 1980's, it has a wide range of uses: coating solvent and diluent, ink special agent and diluent, pesticide emulsifier and pesticide solvent, hydrogen peroxide and banana water special solvent, leather and plastic brightener, precision machine bed cleaning solvent, pulp moisture-proof agent. Compared with the corresponding alkane solvents, the high boiling point aromatic solvent oil has the characteristics of strong solubility, small odor, stable chemical and physical properties, good emulsifying performance, high boiling point, moderate volatility, anhydrous, olefin, chlorine and chlorine. Heavy metal, good leveling property. When used in coating production, its solubility is better than that of xylene. It can improve the leveling and brightness of the film. Suitable for all kinds of grease paint, asphalt paint, alkyd paint, acrylic paint, nitrocellulose paint, epoxy paint, etc. It is also a special solvent for electrostatic spraying of automobiles, bicycles and sewing machines. In the preparation of pesticide emulsifier and pesticide production, toluene and xylene can be replaced as solvent of pesticide emulsifier. The utility model has the advantages of low cost, wide distillation range, high flash point, good solubility gradient, harmless, non-toxic, no effect on efficacy and no assistance to decomposition. The prepared emulsifier has the advantages of high flash point, slow volatilization rate and strong permeability. High boiling point aromatic plasticizers can improve the softness of plastics, make plastics easy to process and shape, improve the high temperature and cold resistance of plastic products, and can be widely used in plastic and rubber industry.
