Nitronaphthalene

Japanese: ニトロナフタレン(英語表記)nitronaphthalene
Nitronaphthalene
An aromatic nitro compound. There are two isomers, 1- (or α-) and 2- (or β-) nitronaphthalene, depending on the position of the nitro group. When naphthalene is nitrated with mixed acid (a mixture of concentrated sulfuric acid and concentrated nitric acid), the 1- and 2- isomers are produced in a ratio of 9 to 1. (Chemical formula) The 1- isomer is a yellow needle-like crystal with a melting point of 61 °C and a boiling point of 304 °C. It becomes 1-naphthylamine when reduced, so it is an important dye raw material. The 2- isomer is a colorless plate-like crystal with a melting point of 79 °C and a boiling point of 312.5 °C (734.4 mmHg).

芳香族ニトロ化合物の一つ。ニトロ基の位置により,1‐(またはα‐)および2‐(またはβ‐)ニトロナフタレンの2種の異性体がある。ナフタレンを混酸(濃硫酸と濃硝酸の混合物)によってニトロ化すると,1‐体と2‐体とが9対1の比で生ずる。(化学式)1‐体は黄色の針状結晶で,融点61℃,沸点304℃。還元されると1‐ナフチルアミンになるので,染料の原料として重要である。2‐体は無色の板状結晶で,融点79℃,沸点312.5℃(734.4mmHg)。
