A problem in the use of many amines as pH buffers is that they are liquids or gases at room temperature and are difficult to obtain pure. Of the solid amines, 4-amino-pyridine, imidazole and Tris are ordinarily available in acceptable purity, but others, such as 2-amino-2-methyl-1,3-propanediol, 2-amino-2-methyl-l-propanol and hexa-methylenediamine, may need further purification, commonly by distillation. However it is difficult to remove residual monoethanolamine and diethanolamine from triethanolamine. A general method for the purification of amines is through the preparation of their hydrochlorides.
