《GB/T 7370-2008对氨基苯甲醚》由TC134(全国染料标准化技术委员会)归口,主管部门为中国石油和化学工业联合会。
本标准代替GB/T 7370-1992《对氨基苯甲醚》。
本标准规定了对氨基苯甲醚的要求、采样、试验方法、检验规则以及标志、标签、包装、运输、贮存、安全和安全技术说明书。
本标准适用于对氨基苯甲醚的产品质量控制,该产品主要用于染料工业中。
本标准与GB/T 7370-1992相比主要变化如下:
――色谱柱由填充柱修改为毛细管柱;
――固定相由丁二酸乙二醇聚酯(PEGS)修改为(5%苯基)甲基聚硅氧烷;
――对氨基苯甲醚及其有机杂质的定量方法由校正面积归一化法修改为峰面积归一法;
――提高了对氨基苯甲醚纯度的一等品和合格品的指标;
――降低了邻氨基苯甲醚含量的一等品和合格品的指标,降低了水分含量的优等品的指标,降低了对氯苯胺、高沸物含量的指标;
――将取样方法规范为采样;
――增加“安全、安全技术说明书”规定。
