Specification
Application
It is mainly used in medicine, dyestuff, pesticide and so on. It is also used in food additives and flavors and fragrances.
Property
Ethyl acetoacetate is colorless liquid with cheerful fruit smell. It is easily soluble in ethanol, ethyl ehter, propylene glycol and ethyl acetate, and soluble in water as 1:12.
Storage
Stored at a dry, shady, ventilated place.
Stability
1. Stable under normal temperature and pressure. Incompatible materials: acids, alkalis, reducing agents, oxidizing agents. It is a low-toxicity category. Avoid breathing vapor and contact with skin.
Chemical properties: It is purple when it meets ferric chloride. When hydrolyzed with dilute acid or dilute alkali, acetone, ethanol and carbon dioxide are generated. Under the action of a strong base, two molecules of acetic acid and ethanol are produced. When catalytic reduction, β-hydroxybutyric acid is formed. In the newly distilled ethyl acetoacetate, the enol form accounts for 7% and the ketone form accounts for 93%. When the ethanol solution of ethyl acetoacetate was cooled to -78°C, the ketone compound was precipitated in a crystalline state. If the sodium derivative of ethyl acetoacetate is suspended in dimethyl ether and a slightly less neutralized amount of dry hydrogen chloride gas is passed at -78°C, an oily enol compound can be obtained.
2. This product is less toxic, rat oral LD503.98g/kg. But with moderate irritation and anesthesia, the production equipment should be sealed and well ventilated. Operators are equipped with protective equipment.
