Benzyl benzoate

1Characteristics and Application

1.1. Molecular formula, structural formula and molecular weightMolecular formula: C12H12O2Molecular weight: 212Structural formula:         1.2. Characteristics

1.2.1. AppearanceBenzyl benzoate is a colorless or pale yellow viscous transparent liquid in the standard conditions. In the following 17 , it becomes white. Benzyl benzoate of high-purity would have faint scent of flowers under long-term storage.

1.2.2. Freezing poingFreezing point: 17In winter, because of being solid, the package of benzyl benzoate may be placed firstly in hot air chamber (35-70 ) or warm water (40-90 ) for water bath, and then it can be used after melting.

1.2.3. Boiling pointBoiling point: 323Because of its high boiling point and low volatilization, it is a kind of flammable, but non-easily-flammable organic solvent.

1.2.4. SolubilityBenzyl benzoate does not dissolve in water, but insoluble in organic solvents. It is a good high-temperature solvent in itself. And it is the only solvent of Musk. Benzyl benzoate has applications for pharmacy and perfume industry just because of its characters that low volatilization of solvent and relative stability of ester.

1.2.5. Plasticity               Benzyl benzoate has good plasticity performance.

As a result of good plasticity, solvent, safety and environmental protection performance, benzyl benzoate is used in the lead agent, leveler, repair agent, and so on in textile auxiliaries. 1.2.6. Safety Performance

1.3. Applications

1.3.1 Main ApplicationsBenzyl benzoate is mainly used in Textile auxiliary, flavor spice, pharmacy, and plasticizer.

1.3.2. The application mechanism in textile auxiliaries and comparison with similar productsBenzyl benzoate is used as lead agent, leveler and repair agent in textile auxiliaries.Mechanism: with the continuous development of the textile industry, cloth has been more and more high-grade. But the more high-grade cloth is, the more compact fabric is. So in dyeing, difficulty of coloring and uniformity is relatively larger. Benzyl benzoate has good plasticity performance. So it swells and draws away fiber to facilitate dye. At the same time, benzyl benzoate is a good solvent to dissolve easily and disperse dye evenly as well, which makes its evenly dyeing and migration property very excellent to dye fiber.Similar properties of materials to benzyl benzoate are methylnaphthalene, dimethylnaphthalene, methyl salicylate, benzene ester. Comparison is as follows,

It is precisely because of its better overall performance. Benzyl benzoate has more and more wide application in textile auxiliary.
