Introduction
Hexanal, also known as butyraldehyde, is an organic compound. Below is an introduction to the properties, uses, preparation, and safety information of hexanal:Properties:- Hexanal is a colorless liquid with a pungent odor.- Hexanal is flammable at room temperature and highly volatile.- Hexanal is soluble in alcohols and ethers, but insoluble in water.Uses:- Hexanal is an important raw material in organic synthesis and can be used to synthesize various compounds, such as alcohols, esters, and aldehydes.- Hexanal is widely used in the preparation of fragrances, rubber antioxidants, dye extracts, and more.Preparation:- The main methods for preparing hexanal are by reacting hexene with oxygen in the air or by hydrogenating hexyne.- The reaction of hexene with air requires high temperature and high pressure, and the reaction product has a high content of hexanal.- The hydrogenation of hexyne is carried out in the presence of a catalyst, such as a copper hydroxide catalyst, under appropriate pressure and temperature conditions.Safety Information:- Hexanal has a pungent odor; contact with hexanal may cause irritation to the eyes, skin, and respiratory tract.- Hexanal is a flammable liquid; avoid exposure to open flames and high temperatures.- When using hexanal, wear protective gloves, masks, and safety goggles.- When storing and handling hexanal, avoid contact with oxidizers and strong acids to prevent hazardous reactions.- Hexanal should be stored away from open flames and heat sources, and used and stored in a well-ventilated area.
