Abstract

Various conditions for the chromatographic analysis of mixtures containing up to 90% cumenehydroperoxide (CHP) are described. It is shown that the analysis may be performed both on glass and stainless steel columns. The effect of metal injection ports and syringes on the stability of CHP depends on the material of which they are made. The relative error of CHP, dimethyl phenylcarbinol, acetophenone, phenol and isopropylbenzene in synthetic mixtures and the reproducibility of the same compounds in samples from a phenol plant are calculated.
