Furfural Diacetateの硝化に於ける中間附加化合物に関する研究 その1

抄録

1) The intermediate product obtained by the nitration of furfural diacetate with nitric acid and acetic anhydride yielded three kinds of crystals melting respectively at 114.5-115.5°, 106-107°, and 105-105.5°. Analytical and other examinations pointed out that they were all furfural diacetate with nitro and acetoxyl groups and they were designated respectively as α-, β-, and γ-nitro-acetin diacetate.
2) Deacetoxylation of nitro-acetin diacetate was examined from various angles and it was found that it could be effected with weak inorganic alkalis, such as sodium acetate, not necessarily requiring pyridine or dimethylaniline, to form 5-nitrofurfural diacetate in a good yield.
