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