Stankovičová M. et al. Acta Fac. Pharm. Univ. Comen. LXII, 2015 (2): 38-42. 40 39 parameters, i.e. activation energy EA determined from temperature dependence of the rate constants. Following the evaluation of complex physicochemical properties of basic esters, the aim of this work is the study of kinetics of their alkaline hydrolysis. In terms of fundamental structural aspects, the influence of alkoxy side chain attached to phenyl ring as well as the substitution on N-phenylpiperazin-1-yl moiety within the structure on the stability is evaluated.
