[6] In the next year, Fittig et al. adopted the pseudocumol terminology, [7] in 1869 Fittig and B. Wackenroder proved that the fraction is a mixture of mesitylene with another trimethylbenzene, for which the name of pseudocumol was retained, [8] and in 1886 Oscar Jacobsen showed that the third trimethylbenzene he discovered earlier is also present.
