IUPAC/Dissociation-Constants: v2.3

This release includes the labeled data, digitization report, method keys, and partial reference keys as part of the IUPAC Digitized pKa Dataset. For more information, please review the Data Digitization Report attached in this repository. Our validation process is ongoing and will continue; please be advised that a few errors and inconsistencies may still exist.

The digitized books in this collection include:

• Serjeant: International Union of Pure and Applied Chemistry, E. P Serjeant and Boyd Dempsey. Ionisation Constants of Organic Acids in Aqueous Solution; Oxford/Pergamon, 1979 (Oxford IUPAC chemical data series)
• Perrin: International Union of Pure and Applied Chemistry, DD Perrin. Dissociation Constants of Organic Bases in Aqueous Solution; Butterworths, 1965
• Perrin Supplement: International Union of Pure and Applied Chemistry, DD Perrin. Dissociation Constants of Organic Bases in Aqueous Solution, Supplement; Butterworths, 1972

Updates from previous version:

• Fix pKa type or values for ~150 entries (many thanks to pkrezel for identifying some of these.)
• Included digitized reference codes for Perrin Supplement and Serjeant data sources. (Removed image scans.)
• Renamed "solvent" to "cosolvent" and cleaned up many of the entries.
• Miscellaneous fix-ups: fixed structural compound info for a few entries, removed a few erroneous entries.
• Applied "Erratum" updates from the Perrin Supplement to fix some small issues in the Perrin data.
