摘要：

A UV-vis spectrophotometric method for measurements of relative acidities in heptane has been developed. The phosphazene base t-BuP4 is used as the deprotonating agent. Its protonated form is a good counterion for the anions of the acids because it is bulky, has delocalized charge, and therefore does not have specific interactions with the anions. A self-consistent scale of relative acidities in heptane spanning for 3 pK(a) units has been constructed.
