| Abstract: | A method for the determination of 2-methylnaphthalene and 2-methylnaphthoquinone-1,4 in reaction solution by GC was developed. Naphthalene was used as an internal standard. The samples were well separated on a DB- 1 capillary column and detected with FID as a detector. The recoveries of the method were 98% - 102%, and RSD was less than 2%. |
