Abstract
The profile of the reaction СН3ОН + МОН → СН3ОМ + Н2О in the presence of an alkali (МОН, М = Li, Na, K) was investigated by the ab initio quantum-chemical method for the gas phase (with allowance for the solvent) within the continuum model. The proton transfer and the formation of the alkaline methoxide molecule in МОН/DMSO/СН3ОН systems (М = Li, Na, K) in the alkali-methanol pre-reaction complexes can take place without their preliminary dissociation and are barrier-free reactions.
