dissociation reaction constant



Happy new year, everyone:
     Here is a problem I need some suggeston, I wonder if anyone could
 tell me where I can get the experimetal dissociation reaction constant
 of OH- + CH3OH(alcohol)---> H2O + CH3O-, or some other theoritcal method
 to calculate it. Thanks in advance.
