参考词条
补充资料:1,2,4-Acid
分子式:C10H9NO4S
分子量:239.25
CAS号:116-63-2

性质:该品为白色或灰色针状结晶,常含半分子结晶水。能溶于热亚硫酸氢钠和碱溶液,不溶于冷的乙醇、乙醚、苯,微溶于水。在空气中变为粉红色,潮湿时更甚。碱溶液在空气中很快地氧化成棕色,中性溶液略显蓝色荧光。

制备方法:以2-萘酚为原料,经碱熔、亚硝化、磺化而得。原料消耗定额:2-萘酚(99%)840kg/t、亚硫酸氢钠(98%)1500kg/t、硫酸(92.5%)1600kg/t。

用途:酸性媒介染料及酸性络合染料中间体。用于制造酸性络合桃红B、酸性媒介黑R和酸性络合盐GGN、酸性媒介枣BN等。也用于比色法测定磷酸盐及钙盐。
