Triisopropyl borate was synthesized with high yield from 2 propanol and boron oxide by using calcium hydride as drying agent to remove resultant water.

RESULTS: The transdermal osmotic process fitted to a zero order kinetic mechanism. The osmotic enhencer effect of 2 propanol was listed below: 15%> 10%>5%.

Threc calculating methods of dividing into liquid stratum of cyclohexane (1)-2-propanol(2)-water (3) ternary system liquid-liquid equilibrium have been introduced.
