1, 8-diaminonaphthalene, also known as 1, 8-naphthalene diamine, 1, 8-naphthalene dimethylamine, is an organic compound, the molecular formula is C10H10N2, is a brown-red solid, soluble in ethanol, ether, chloroform, slightly soluble in water, easy to be oxidized.The preparation process of 1, 8-diaminonaphthalene is to synthesize dinitronaphthalene through nitration, thus obtaining a higher yield and a higher purity of 1, 8-dinitronaphthalene, as the raw material for the next step of the reaction, and then 1, 8-dinitronaphthalene catalytic hydrogenation synthesis, 1, 8-diaminonaphthalene, improve its yield and selectivity.
1, 8-diaminonaphthalene is mainly used AS an intermediate in the synthesis of dyes. It is widely used in the synthesis of black oil-soluble dyes, ci. solvent red (135#), solvent orange (60#), etc. These dyes play an important role in the coloring of PS, AS, ABS, hard PVC, PET and other substances.In addition, 1, 8-diaminonaphthalene can also be used as a colorimetric reagent. 1, 8-diaminonaphthalene and selenite interact with each other in a certain PH range. Then, toluene is used to quantitatively extract the colored substances generated in aqueous solution.
In recent years, the output of 1, 8-diaminonaphthalene has been declining in China.On the other hand, in recent years, the development of domestic 1, 8-diaminonaphthalene downstream dye market slowed down, resulting in its demand.
