production method
Direct esterification of isovaleric acid and ethanol under sulfuric acid catalysis. After the reaction mixture is cooled, it is neutralized with sodium carbonate, washed with water, dried, and fractionated to obtain the product.

(CH3)2CHCH2COOH+CH3CH2OH[H2SO4]→(CH3)2CHCH2COOCH2CH3+H2O

The finished product can also be obtained by isobutyronitrile and ethanol under the catalysis of sulfuric acid, heating and refluxing for 10 hours, neutralizing, washing with water, separating the ester layer and then fractionating the finished product.

 

Basic use
Ethyl isovalerate is a food flavor permitted by China's "Sanitary Standards for the Use of Food Additives". It is mainly used to prepare fruit flavors such as pineapple, apple, lemon, and grapes. The amount used in gum is 80～430mg/kg; 29mg/kg in candies, 27mg/kg in baked goods} 7.5mg/kg in cold drinks; 5.0mg/kg in puddings; 4.9mg/kg in soft drinks. It is occasionally used in cosmetic fragrances to increase the spreading power of top fragrance. It can be used in edible flavors in large quantities, mainly in apple, pineapple and rum types. It is also good to use its fruity aroma in gum. It is also occasionally used in tobacco flavors. GB2760—96 stipulates that it is allowed to use edible spices.

The focus of the development of the chemical industry-fine chemicals Fine chemicals include medicines, pesticides, synthetic dyes, organic pigments, paints, fragrances and essences, cosmetics and toiletry products, soaps and synthetic detergents, surfactants, printing inks and additives, adhesives, photosensitive materials, and magnetism Materials, catalysts, reagents, water treatment agents and polymer flocculants, papermaking auxiliaries, leather auxiliaries, synthetic material auxiliaries, textile printing and dyeing agents and finishing agents, food additives, feed additives, animal drugs, oil field chemicals, petroleum additives And refining additives, cement additives, mineral flotation agents, foundry chemicals, metal surface treatment agents, synthetic lubricants and lubricant additives, automotive chemicals, aromatic deodorants, industrial antibacterial and antifungal agents, electronics More than 40 industries and categories including chemicals and materials, functional polymer materials, and biochemical products. With the development of the national economy, the development and application of fine chemicals will continue to open up, and new categories will continue to increase. The term fine chemicals has been in use for a long time, originally referring to chemical products with small yields, high purity, and high prices, such as medicines, dyes, and coatings. However, this meaning has not fully revealed the essence of fine chemicals. Since the 21st century, experts from various countries have gained some new insights into the definition of fine chemicals. Some countries in Europe and the United States call chemical substances that are produced and sold according to different chemical structures as fine chemicals. Small, processed and formulated products with special functions or end-use properties are called special chemicals. China and Japan collectively refer to these two types of products as fine chemicals.

Chemical industry

2021-07-07

Chemical industry is the abbreviation of "chemical process", "chemical industry", "chemical engineering" and so on. Any technology that uses chemical methods to change the composition and structure of substances or to synthesize new substances belongs to chemical production technologies, that is, chemical processes, and the resulting products are called chemicals or chemical products. In the beginning, these products were produced in handicraft workshops, and later evolved into factories, and gradually formed a specific production industry, the chemical industry. Chemical engineering is a science that studies the common laws of the production process of chemical products. The relationship between mankind and chemical industry is very close. Some chemical products have played an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization.
