Determining the pKa1 and pKa2 Values of 4,4′-Trimethylenedipiperidine (TMDP), a Diprotic Organic Base with Unknown pKa Values

The negative logarithm of the acid dissociation constant values (pK(a1) and pK(a2)) of 4,4 `-trimethylenedipiperidine (TMDP) was determined by a pH metric titration at 298 K. The experimentally determined pK(a) values were compared with the predicted pK(a) values by chem-bioinformatics software like...
