Abstract: The content of 2-camphanone in synthetic camphor was determined by GC method, and at the same time the content of total ketones in the synthetic camphor was determined by chemical method. The results showed that the content of 2-camphanone by GC area normalization method was accordant with the content of total ketones by chemical method in numerical value after the content difference comparison of these two methods. They were suitable to synthetic camphor products in different grades of quality mentioned in the national standard GB/T 4895-2007. GC method could shorten the analysis time with good accuracy and reliability, so it is used in the national standard GB/T 4895-2007 《synthetic camphor》 as the technical requirement for synthe-tic camphor content, which has been published on Mar 5, 2007 and will be executed from September 1, 2007.

Key words: synthetic camphor, 2-camphanone, total ketones, content determination
