The synthesis of 2-carboxy-4-hydroxy-3-quinoline-alkylcarboxylic acids is described, these acids being prepared by the condensation of the triethyl esters of α-oxalyldicarboxylic acids with aniline. By heating the anils thus obtained, esters are for

It has been established that in many cases the system constants used in the Solvation parameter model as well as the corresponding log k values can be linearized in the same NSP and NSP?scale, respectively, which shows the compatibility of both model

It is shown how in RP chromatography the Everett equation for ideal phase equilibriums can be used to estimate SP values (SP = log xs/x1, xs and x1 denoting the modifier mole fractions in the stationary and mobile phases, respectively) which are in a
