By gaschromatography, infrared spectrum and GC - MS quantitative and qualitative analysis, cyclopentanol was con firmed as the purposive product and it was more than 99% in content after separation.
Analytical technique of gaschromatography (GC) has been widely used in many fields due to its many advantages, such as high separation efficiency, fast analysis speed, good selectivity and so on.
