Abstract:
A qualitative method to determine eyelohexylbenzene content in alkylation reaclion solution cata.lyzed by ionie liquid was developed, with gas chromatogram and n-deeane as interal standard material. Thecorrelation coellicient of standard curves of benzene and eyelohexylbenzene are both more than 0. 999. The analysis result shows that the relalive devialions belween real values and measured values of benzene and cyclyhexylbenzene are less than 5.2%6 , recoveries range from 97.96 %6 to 105.13%, and precision are 1.60%and 1.62% ,respeclively, which shows high stabilily and reliability.
