Bisphenol 2,2- full name A two (4- hydroxy phenyl) propane, referred to as two phenol based propane. White crystal, melting point of 156 to 158 degrees Celsius, is mainly used for the preparation of epoxy resin and polycarbonate chemicals. It is widely used in many fields, and it is widely used in food and beverage packaging, as well as in special medical supplies and packaging. Bisphenol A can also be used in many non FDA control of consumer goods, such as children's toys, etc..
Tengzhou City Xiangying Analysis Technology Co., Ltd. of bisphenol A (BPA) in polycarbonate resin and molded product XiangyingGC7990plus gas chromatography detection method was established. Samples were extracted by acetone and then dried, dissolved in potassium carbonate solution, and then the reaction was obtained. The derivative was extracted by hexane and analyzed by 7990. The results showed that the method was linear in the range of 0.05 ~ 1.0 mg / L, the correlation coefficient of 0.9989, linear range from 1.0 to 10.0mg/l. Correlation coefficient of 0.9999; the detection limit of the method was 0.05 mg / kg; the average recovery rate was 93.0% ~ 100.5%; relative standard deviation was 4.2% to 7.2 percent. The method is accurate and sensitive, and can be used for the analysis of bisphenol A in the actual polycarbonate resin and its products.
双酚A全名2,2-二(4-羟基苯基)丙烷,简称二酚基丙烷。白色晶体,熔点156～158℃,是主要用于制备环氧树脂和聚碳酸酯的化学物质。它在很多领域具有广泛应用,普遍应用于食品和饮料的包装以及特定医学用品及其包装中。双酚A也可以应用在许多非FDA管控的消费品中,如儿童玩具等。
滕州市翔鹰分析技术有限公司建立了聚碳酸酯树脂及其成型品中双酚A(BPA)的XiangyingGC7990plus气相色谱检测方法。样品经丙酮提取后挥发至干,用碳酸钾溶液溶解,再衍生反应。衍生产物经正已烷提取后,采用7990进行分析。结果表明,方法的线性范围为0.05～1.0mg/L,相关系数为0.9989,线性范围为1.0～10.0mg/L,相关系数为0.9999;方法的检出限为0.05mg/kg;平均回收率为93.0%～100.5%;相对标准偏差为4.2%～7.2%。该方法准确、灵敏,可用于实际聚碳酸酯树脂及其成型品中双酚A的分析。
