Ethyl acetoacetate
Detailed introduction
Ethyl acetoacetate, also known as ethyl acetoacetate, with the chemical formula C6H10O3, is an important raw material for organic synthesis, is a colorless or slightly yellow transparent liquid with a fruity smell. It is used in the synthesis of dyes and drugs, and is also an important intermediate in other organic synthesis.
Properties
Physical Properties: colorless to light yellow clarified liquid, ether-like and apple-like aroma, and fresh rum aroma, sweet and with some fruity aroma. Relative density 1.0282, melting point - 45℃, boiling point 180.4℃. Slightly soluble in water, soluble in ethanol, ether, benzene, chloroform, petroleum ether and other organic solvents.
Chemical Properties: with the dual nature of ketone and ester, can occur ketone and enol type isomerism. In the enol type structure, due to the existence of conjugated system, making ethyl acetoacetate has a certain acidity, and its enol type structure can be reacted with sodium metal to generate sodium salt. At the same time, it can also undergo a variety of organic reactions such as ester condensation reaction and Claisen condensation reaction.
Uses
Raw material for organic synthesis: Ethyl acetoacetate is an important intermediate for the synthesis of many organic compounds. For example, it can be used for the synthesis of 4 - methyl - 7 - hydroxy coumarin, which is an important spice; can also be used for the synthesis of pyrimidine, pyrazolone and other heterocyclic compounds, these heterocyclic compounds in the synthesis of drugs with important applications.
Pharmaceutical industry: In the pharmaceutical field, ethyl acetoacetate can be used to synthesize antimalarials, sedative-hypnotics and so on. For example, it is an important raw material for the synthesis of barbiturates, which are sedative, hypnotic and anticonvulsant.
Food additives: it has a unique aroma, can be used as edible spices, used to blend apples, bananas, strawberries and other fruit-based flavors, as well as rum, cream and other aroma flavors, widely used in the food, beverage and other industries, in order to enhance the aroma and flavor of the product.
Other applications: in the paint industry, it can be used as solvent and plasticizer, which helps to improve the performance of coatings; in the plastics industry, it can be used as the intermediate of plasticizer, which improves the flexibility and processing performance of plastic products.
