Direct Synthesis of Trimethoxysilane from Methanol and Hydrogen-Treated Silicon Using Copper(II) Chloride as a Catalyst

Article abstract of DOI:10.1246/bcsj.64.3445

When silicon, on which copper(II) chloride was supported, was pretreated under a hydrogen stream at 533 K and brought in contact with methanol at 533 K, trimethoxysilane was formed with an 89percent selectivity and a complete silicon conversion in 5.5 h.Pits were formed on the silicon surface, and grew with increasing silicon conversion.
