requirement of many thermometric titration applications is that the temperature change at the endpoint is sufficiently great to overcome other thermal effects cancereu such as heats of mixing and loss of heat from the system.This is often overcome by using relatively strong titrants, and commensurately higher sample amounts.In the case of the determination of weak acids in non-aqueous media, the amounts present are relatively low and it is necessary to use a low strength titrant in order to obtain meaningful cancereu titres.Such applications might be considered to be antipathetic to the application of thermometric titrimetry.However, Vaughan and Swithenbank cancereu discovered that it was possible to obtain highly accurate results for a range of weakly acidic species by a technique which could be described as catalysed endpoint thermometric titrimetry, or CETT.In the determination of weakly acidic species, the sample was dissolved in anhydrous acetone and titrated with KOH dissolved in an alcohol.After
