Ethyl acetate, ethyl acetate, benzene, toluene, acetone, ethanol and butanol are formulated into a mixed solvent according to a certain weight percentage, which is called banana water. Pure banana water is a colorless, transparent and volatile liquid. It has a strong banana odor, is slightly soluble in water, is soluble in various organic solvents, and is flammable. It is mainly used as a solvent and thinner for painting.
First, the preparation method
In a weight ratio, n-butyl acetate 15%, ethyl acetate 15%, n-butanol 10 to 15%, ethanol 10%, acetone 5 to 10%, benzene 20%, xylene 20%, and then thoroughly mixed Even can get banana water.
Second, the matters needing attention
1. The ratio of various raw materials in banana water can be adjusted properly. In addition, the raw materials used can also be replaced. For example, if ethyl acetate is less, it can be replaced with a hetero ester; sometimes, different raw materials can be selected depending on the use of banana water.
2. The addition of ketones can increase the brightness of the paint film. Generally, the benzenes should not exceed 40%.
3. In the preparation of banana water, the moisture content of various raw materials should be minimized as much as possible.
Do not use benzene, the boiling point is too low, the evaporation rate is too fast, easy to whiten, especially when the humidity is high, the most important is the danger and danger.
Banana water configuration method
Banana water, also known as water that day, the main component is xylene, highly volatile and flammable, toxic, dangerous goods, mainly because there is a stronger banana smell, so called banana water.
