butyl 2-methylbutyrate - Introduction
butyl 2-methylbutyrate, also known as butyl formate, is an organic compound. The following is a description of the nature, use, formulation and safety information of butyl 2-methylbutyrate:
Nature:
butyl 2-methylbutyrate is a colorless liquid with a fruity aroma. It has a small density and is insoluble in water at room temperature, but soluble in a variety of organic solvents. It has a lower boiling point but a higher flash point.
Use:
butyl 2-methylbutyrate is mainly used as a solvent and fragrance additive. Because of its fruit flavor, it is often used in food, perfume, medicine and cosmetics. In addition, it can also be used to manufacture products such as coatings, inks and plastics.
Preparation Method:
butyl 2-methylbutyrate is usually prepared by esterification. A common method is the esterification of methanol with butyric acid over an acid catalyst to produce butyl 2-methylbutyrate and water. The reaction conditions require control of temperature and reaction time to obtain high yield and purity.
Safety Information:
butyl 2-methylbutyrate is generally less toxic under normal conditions of use. However, as an organic compound, it may cause certain irritations and allergic reactions to the human body. Therefore, it is necessary to pay attention to proper ventilation and protective measures during use to avoid contact with skin and eyes. During storage and handling, attention should be paid to fire prevention and avoid contact with oxidants and other substances. If ingested or inhaled by mistake, you should seek medical attention in time.
