Isobutyraldehyde is an important organic compound, which is widely used in the field of chemical production raw materials. It has special properties and uses, and plays a key role in the manufacturing process of many chemical products. In this paper, the properties and uses of isobutyraldehyde will be introduced in detail.

1. the nature of isobutyraldehyde

isobutyraldehyde is a colorless transparent liquid with a pungent odor. Its molecular formula is CH3CH2CH2CHO and its molecular weight is 72.11. Isobutyraldehyde has a boiling point of 64.5°C, a melting point of -86.6°C and a density of 0.801g/cm3. It is soluble in water, ethanol, ether and other organic solvents, but difficult to dissolve in petroleum ether. The chemical properties of

isobutyraldehyde are active and prone to oxidation, reduction, addition, condensation and other reactions. It is easily oxidized to isobutyric acid in air and forms isobutanol with hydrogen addition. In addition, isobutyraldehyde can also be condensed with many compounds to produce a variety of derivatives.

2. the use of isobutyraldehyde

1. Synthetic rubber
isobutyraldehyde is one of the important monomers of synthetic rubber, mainly used in the production of butadiene rubber. Butadiene rubber has excellent wear resistance, tear resistance, anti-aging performance, widely used in the production of tires, tape, rubber hose and other rubber products.
2. Plastic additive
isobutyraldehyde can be used as a plastic additive to improve the performance of plastics. It can improve the toughness, impact strength, heat resistance and other properties of plastics, and extend the service life of plastics.
3. synthetic perfume
isobutyraldehyde can be used to synthesize various fragrances, such as ethyl butyrate, isoamyl butyrate, etc. These spices have strong fruity and floral aroma, and are widely used in food additives, daily chemical products and other fields.
4. Pharmaceutical intermediates
isobutyraldehyde can be used as pharmaceutical intermediates for the production of some drugs. For example, it can be used to synthesize the anti-tuberculosis drug isoniazid, the anti-tumor drug cyclophosphamide, etc.

In short, isobutyraldehyde has a wide range of applications in the field of chemical production raw materials, and plays an important role in promoting the development of the chemical industry.
