"In rats treated with the silane, the methanol level was high 1 hour after treatment, indicating rapid absorption. The level was still elevated at 24 hours, indicating sustained release of methanol. Animals treated with methanol exhibited a much lower methanol level at 24 hours, showing that methanol alone is metabolized fairly rapidly. Silicon levels after trimethoxysilane administration were elevated at 1 hour and even higher at 4 hours, indicating continuous release of this element."
