Essence formula for cigarettes, daily chemical products (such as cosmetics and detergents), and as organic solvent. As an intermediate in organic synthesis, it participates in the production process of chemical products =========================================================================== According to its chemical structure and industrial production practices, its main synthesis methods are as follows: Esterification reaction method: This is the most commonly used synthesis method in industry. Ethyl isobutyrate is synthesized by esterification reaction between isobutyric acid (2-methylpropionic acid) and ethanol under acidic catalyst (such as concentrated sulfuric acid). The reaction equation can be expressed as: (CH₃)₂CHCOOH + CH₃CH₂OH ⇌ (CH₃)₂CHCOOCH₂CH₃ + H₂O This reaction is reversible and is usually increased in yield by removing the generated water or using excess alcohol. Other possible methods include reacting isobutyrylchloride with ethanol or catalyzing esterification through biological enzymes, but these methods are less commonly used on an industrial scale Uses : used to prepare fruit essence such as butter, strawberry, cherry, etc., Synonyms : :2-methylpropanoic acid ethyl ester;ethyl 2-methyl propanoate;Ethyl Iso Butyrate (Iso C-4 Ethyl Ester); ;ethyl 2-methylpropanoate; Molecular Structure :
