ABSTRACT:
A method of obtaining deuterated compounds from compounds having an abstractable proton comprises contacting the proton-containing compound with a porous ion exchange resin which contains at least some deuterons. The reverse process of substituting protons for deuterons in deuterated compounds is also described. Highly pure products can be obtained.
