1.2 Properties

1.2.1 Appearance

In standard conditions, benzyl benzoate is a colorless or pale yellow viscous transparent liquid. In temperature conditions of 17 degrees centigrade or lower, it will be solidified into white solid. Benzyl benzoate of high-purity would send out slight fragrance.

1.2.2 Freezing Point

Freezing point: ≥17℃

In winter, because of being solid, the package of benzyl benzoate can be placed in hot air chamber (35-70 ℃) or warm water (40-90 ℃), it can be used after melted.

1.2.3 Boiling Point

Boiling point: 323℃

Due to its high boiling temperature and low volatility, it is a kind of flammable, but non-easily-flammable organic solvent.

1.2.4 Solubility

Benzyl benzoate is insoluble in water but soluble in organic solvents. Benzyl benzoate itself,a high-temperature solvent, is the only solvent of Musk. Benzyl benzoate has applications to pharmacy and perfume industry just because of its characters of low volatilization and relative stability.

1.2.5 Plasticity

Benzyl benzoate has good performance of plasticity.

For its good performance of plasticity, solvent, safety and environmental protection, benzyl benzoate has been widely used into synthesis of lead agent, leveling agent, repair agent, and so on.

1.3 Applications

1.3.1 Main Applications

Benzyl benzoate is mainly used in the area of textile auxiliary, fragrance and flavor, pharmacy, plasticizer and so on.

1.3.2 The Application Mechanism in Textile Auxiliaries and Comparison with Other

  Similar Products.

Benzyl benzoate can be used to lead agent, leveling agent and repair agent of textile auxiliaries.

Mechanism: With the development of the textile industry, the materials are of higher-grade. The higher-grade cloth is, the more compact fabric is. So in dyeing, there are more difficulties in coloring and uniformity Due to the good plasticity performance, benzyl benzoate makes the fiber swell and undraw so that the fiber will be dyed easily. At the same time, benzyl benzoate is a good solvent to dissolve and disperse dye evenly. Since its quite good dye migration performance, benzyl benzoate could be developed as leveling agents and lead agent.

Due to its comparatively great comprehensive performance, benzyl benzoate has wider and wider application in textile auxiliary. There are many other materials, which have similar properties with benzyl benzoate, such as methylnaphthalene, dimethylnaphthalene, methyl salicylate, and benzene ester. Comparison are as follows:
