Methanediol decomposition mechanisms: A study considering various ab initio approaches

Stanislav B�hm, Diana Antipova, Josef Kuthan

Open publisher page 18 citations

Abstract

The alternative decomposition reactions CH2(OH)2 → CH2O + H2O and CH2(OH)2 + H2O → CH2O + 2H2O are investigated using the semiempirical PM3 as well as the ab initio HF/3-21G, HF/6-31G, HF/6-31G**, and MP2/6-31G** calculations. Reactants, products, and appropriate transition states are located on corresponding potential energy surfaces and compared with those reported in earlier studies. © 1996 John Wiley & Sons, Inc.
