Properties and stability
Avoid contact with strong oxidizing agents.
Storage method
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. should be kept away from oxidizer, do not store together. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.
Synthesis method
Produced from the hydrolysis of 2,5-dimethylfuran. Another synthesis method is to react sodium ethyl acetoacetate with pure iodine to form diethyl diacetyl succinate, which is then hydrolyzed with 10% sodium hydroxide solution. The reaction solution was saturated with anhydrous potassium carbonate to precipitate acetone. Extract with diethyl ether, evaporate the diethyl ether from the extract, distill the residue, and collect the 192-194°C fraction to obtain a colorless product.
Purpose
Used as high boiling point solvent for synthetic resins, nitrocellulose spray paints, colorants, printing inks, etc., leather tanning preparations, rubber vulcanization accelerators and Pesticides and pharmaceutical raw materials.
