This paper uses established experimental methods to determine the colloidal pKa values for a variety of weak organic acids found in a variety of lipophilic extractives of Pinus radiata at 20C and 50C. The 50C colloidal pKa values, to the knowledge of the authors, are published for the first time in this paper. The data will hopefully lead to a better understanding of how these weak organic acids interact in the 50C temperature range of modern pulp and papermaking. The colloidal pKa values for behenic, lignoceric and cerotic acids are also believed to be published for the first time in this paper
