Biphasic systems may be stabilized by the use of __________

Biphasic systems may be stabilized by the use of __________ Correct Answer deuterated water

Biphasic systems may be stabilized by the use of deuterated water (D2O) as it reduces the rate of thermal inactivation. But it does cause an increase in the pKas of ionizing groups by about 0.4 with the associated changes in the pH-activity and pH-stability relationships. Though, the cost of deuterated water is high, the small amount necessary and the ease with which it may be recovered at the end of a catalytic process makes it useful to be used in biphasic systems.
