Descripción

Descripción general

Deuterium oxide (D₂O) also known as heavy water is deuterated water. It is safe and inexpensive source of deuterium (D) for the D/H exchange reactions.[1] The equilibrium constant for the exchange of deuterium between hydrogen (H) and D₂O molecules has been determined.[2] Reports suggest that gelatin gels prepared in D₂O show higher rigidity than gels prepared in water.[3] The influence of temperature on the heat capacity of deuterium in crystalline and liquid state was studied calorimetrically and its melting point, enthalpy and entropy of fusion were determined.[4] Its utility as a potential therapeutic agent in treating human pancreatic cancer has been studied.[5]

Aplicación

Deuterium oxide may be used in the following processes:

• As a NMR solvent.[6]
• Preparation of β-deuterated alcohols.[1]
• For the adsorption of neutrons in atomic reactors.[4]
• Deuterium transfer agent in combination with hexamethyldisilane in the preparation of 1,2-dideuterioalkenes from alkynes.[7]
