Banana water is also called Tianna water. Its main component is xylene, which is highly volatile, flammable, explosive and toxic. It is a dangerous product. It is called banana water mainly because it has a strong banana smell.

Prepare a mixed solvent of ethyl acetate, ethyl acetate, benzene, toluene, acetone, ethanol, and butanol according to a certain weight percentage, which is called banana water. Pure banana water is colorless and transparent A volatile liquid with a strong banana smell, slightly soluble in water, soluble in various organic solvents, flammable, and mainly used as a solvent and thinner for spray paint.

1. Preparation method< /p>

According to weight ratio, take 15% n-butyl acetate, 15% ethyl acetate, 10-15% n-butanol, 10% ethanol, 5-10% acetone, 20% benzene, and 20% xylene , and then mix it thoroughly to make banana water.

2. Precautions

1. The ratio of various raw materials in banana water can be adjusted appropriately. In addition, the raw materials used can also be replaced. For example, if ethyl acetate is small, miscellaneous esters can be used instead; sometimes different raw materials can be selected according to the different uses of banana water.

2. The addition of ketones can increase the brightness of the paint film, and benzene should generally not exceed 40%.

3. When preparing banana water, the moisture content of various raw materials should be reduced to a minimum.

Do not use benzene. The boiling point is too low, the evaporation rate is too fast, and it is easy to whiten, especially when the humidity is high. The important thing is that it is harmful and dangerous.

Banana water is generally called a thinner. The thinner of nitrocellulose paint imported in the 1920s was due to the banana-flavored n-butyl acetate and ethyl acetate. ester, commonly known as banana water; now the formulas of diluents for various paints are different. The general reference formula of diluent for nitrocellulose paint is n-butyl acetate 20%, ethyl acetate 20%, n-butanol 10-15% %, ethanol 5%, acetone 5-10%, toluene 40%, for high-end products, add ethylene glycol ether acetate 5-10%, methyl isobutyl ketone 10%. Do not use benzene, the boiling point is too low, the volatilization speed Too fast and easy to bleach, especially when the humidity is high, the most important thing is the harm and danger
