- W2004387641 abstract "The matrix isolation technique has been used to investigate the initial products of the room and high temperature reaction of trimethylaluminum with methanol and its isotopomers, as well as water, in a flowing reactor system. Reaction went substantially to completion as indicated by a dramatic reduction of bands due to parent (CH3)3Al when dilute samples of Ar/CH3OH were added to the flowing gas mixture, and vice versa. At least two products were formed, an initial intermediate that has been identified as (CH3)2AlOCH3, and one or more oligomers of this species (i.e. dimers and/or trimers). Heating the reaction zone above 200°C following by matrix trapping led to complete destruction of the bands due to (CH3)2AlOCH3, and an increase in the bands due to the oligomers. The production of CH3D as was also noted with CD3OD was employed, but not when CD3OH was used. Ab initio calculations at the RHF/6-31G* and B3LYP/6-31G* levels were carried out on (CH3)2AlOCH3; these calculations support the identification of this species. Similar experiments involving (CH3)3Al and H2O did not lead to any new product bands, although reaction apparently occurred in the reaction zone, as evidenced the growth of strong bands due to CH4." @default.
