DESCRIPTION

5-Nitrofurfural Diacetate

Product name:5-Nitrofurfural Diacetate

Description of properties: very light yellow crystalline powder.

CAS: 92-55-7

Molecular weight: 243.17

Molecular formula: C9H9NO7

Content: ≥98.5%

Melting point: 89-93°C

Production method:

It is obtained by nitrification and esterification of furfural. Add acetic anhydride to the reaction pot, cool to -5 ° C, add 1/5 of the mixed acid (nitric acid and sulfuric acid), and then add a mixture of nitric acid and furfural (1:2 by volume) at the same time to control the temperature. After about 0 °C, about 5-6h is added, and a part of furfural is continuously added dropwise. Then, stirring for 1 h, adding water and sodium carbonate solution, heating to 55-62 ° C, and keeping warm for 1 h. Cool to 15 ° C, filter, wash with water, dry to obtain the finished product, the yield of 85%.
