β-萘酚正名2-萘酚,又称乙-萘酚,是一种白色至淡红色的片状结晶。在空气中长期贮存时,颜色变深。其分子结构为:比重1.217(4°),溶点111～113℃,沸点294℃,不溶于冷水,但溶于热水。25℃时在水中的溶解度0.074g/l,能升华并与蒸汽一同挥发。溶于乙醇、乙醚、氯仿和苯等有机溶剂和碱液中。具有很强的表面活性,在锡、铅电解作业中能增加阴极沉积物的附着力,使结晶致密,表面平整;当电解液中加入动物胶时,β-萘酚对阴极极化作用大
Beta-naphthol 2-naphthol, also known as B-naphthol, is a white to pink flaky crystal. Long-term storage in the air, the color becomes darker. Its molecular structure is: specific gravity 1.217 (4 °), melting point 111 ~ 113 ℃, boiling point 294 ℃, insoluble in cold water, but soluble in hot water. The solubility in water at 25 ° C is 0.074 g / l, which sublimates and evaporates with the steam. Soluble in ethanol, ether, chloroform and benzene and other organic solvents and lye. Has a strong surface activity, in the tin, lead electrolysis operations can increase the adhesion of cathode deposits, the crystallization density, the surface smooth; when added to the electrolyte animal glue, β-naphthol on the cathode polarization effect
