橡胶粘合增进剂新癸酸钴中丙酸含量的测定

Determination of Propionic Acid Content in Rubber Adhesion Promoter Cobalt Neodecanoate

研究气相色谱外标法测定橡胶粘合增进剂新癸酸钴中丙酸含量。结果表明:气相色谱外标法能快速、准确地定量测定新癸酸钴中丙酸含量,测定的相对标准偏差为0. 4%;与气相色谱内标法相比,该方法操作简单,准确性提高,可用于新癸酸钴生产现场的质量监测。

The gas chromatography with external standard method was used to determine the content of propionic acid in rubber adhesion promoter cobalt neodecanoate. The results showed that,the gas chromatography with external standard method could quickly and accurately determine the content of propionic acid in cobalt neodecanoate with a relative standard deviation of 0. 4%. Compared with the internal standard method,the external standard method was simple and possessed better accuracy. It could be used for quality control of cobalt neodecanoate production.
