The PMDA method for determining hydroxyl and primary and secondary amino groups was applied on the semimicro scale. A sample containing 0.4 to 0.6 mequiv. of amine or hydroxyl was reacted with 25 ml of 0.04 M PMDA in a routine analysis. The unconsumed PMDA was titrated with 0.08 N base. For colorless clear samples, the phenolphthalein endpoint was used; for colored or turbid samples, a potentiometric titration is recommended. Further scaling down of the method may be feasible by increasing the PMDA/OH ratio.
