화학적 성질
dark purple to brown-black powder정의
ChEBI: A naphthoquinone that is 1,4-naphthoquinone in which the hydrogens at positions 5 and 8 are replaced by hydroxy groups.제조 방법
1,8-Dinitronaphthalene and 1,5-Dinitronaphthalene mixture or both alone and one of sulfur 40% fuming sulfuric ACID reaction, the product (5, 8 – dihydroxy – naphthoquinone) into Sulfurous acid?hydrogen salt.Purification Methods
It crystallises in red-brown needles with a green shine from EtOH. It also crystallises from hexane and is further purified by sublimation at 2-10mm. [Huppert et al. J Phys Chem 89 5811 1985.] It is sparingly soluble in H2O but soluble in alkalis. The diacetate forms golden yellow prisms from CHCl3, m 192-193o and the 5,8-dimethoxy derivative has m 157o (155o) (from pet ether) [Bruce & Thompson J Chem Soc 1089 1955, IR: Schmand & Boldt J Am Chem Soc 97 447 1975, NMR: Brockmann & Zeeck Chem Ber 101 4221 1968]. The monothiosemicarbazone has m 168o(dec) from EtOH [Gardner et al. J Am Chem Soc 74 2106 1952]. [Beilstein 8 H 412, 8 III 3600.]5,8-Dihydroxy-1,4-naphthoquinone 준비 용품 및 원자재
