苯酚是重要的有机化工原料。目前,由石油化工合成制得的苯酚已占主要地位。随着合成纤维等新兴工业的发展,对苯酚的质量,例如有机杂质含量的控制,提出了严格的要求。原来用于控制苯酚质量的主要试验方法——凝固点、水溶性等已不能满足要求,因此,国内外陆续采用气相色谱法测定苯酚中的有机杂质。 Phenol is an important organic chemical raw materials. At present, the phenol synthesized by the petrochemical industry has dominated. With the development of emerging industries such as synthetic fibers, stringent requirements are placed on the quality of phenol, such as the control of organic impurities. The original test methods used to control the quality of phenol - freezing point, water-soluble and so can not meet the requirements, therefore, one after another using gas chromatography to determine the organic impurities in phenol.
