Sec-butyl acetate is a notable compound in both industrial and laboratory settings. Here are 10 essential facts that you should know about this versatile ester.

1. Chemical Composition

Sec-butyl acetate is an ester formed from acetic acid and sec-butanol. Its chemical formula is C6H12O2, and it has a molecular weight of 116.16 g/mol. The structure features a butyl group attached to an acetate moiety, contributing to its unique properties.

2. Physical Properties

This ester is a colorless liquid with a fruity smell, reminiscent of apples or pears. Its boiling point is approximately 99°C (210°F), while its density is about 0.876 g/cm3 at 20°C. Such characteristics make it ideal for various applications, especially in solvents and coatings.

3. Solubility

Sec-butyl acetate is moderately soluble in water but highly soluble in many organic solvents like ethanol and ether. This dual solubility allows it to act as a bridge in formulations involving both polar and non-polar substances.

4. Industrial Applications

One of the primary uses of sec-butyl acetate is as a solvent in paint, varnish, and coatings. It helps to dissolve organic compounds, improving the application consistency and drying times. Additionally, it serves in the production of adhesives and inks.

5. Flavoring and Fragrance

Due to its pleasant odor, sec-butyl acetate is also utilized in the food and fragrance industries. It is employed as a flavoring agent in candies, baked goods, and beverages, giving them a fruity note.

6. Safety Profile

Despite its versatility, caution is necessary when handling sec-butyl acetate. It is classified as a moderately hazardous substance. Inhalation or prolonged skin contact may lead to irritation, and exposure must be controlled to maintain a safe workplace environment.

7. Environmental Considerations

Sec-butyl acetate can contribute to air pollution when volatile organic compounds (VOCs) are released into the atmosphere. Regulatory bodies often monitor its usage, and businesses are encouraged to adopt eco-friendly practices to limit environmental impact.

8. Regulatory Status

This compound is subject to various regulations in different countries. In the United States, the Occupational Safety and Health Administration (OSHA) regulates sec-butyl acetate to ensure workplace safety. Manufacturing and use must comply with relevant guidelines to minimize health risks.

9. Alternatives

While sec-butyl acetate is popular, alternatives such as ethyl acetate or methyl acetate are also available. Each of these solvents has its own characteristics and should be selected based on specific application requirements.

10. Future Trends

As industries move toward greener solutions, the demand for safer and more environmentally friendly solvents, including sec-butyl acetate, is likely to grow. Innovations in sustainable practices and formulations may enhance its applications across various sectors.
