Procedure

1 mole of n-butanol and 1.5 moles of trimethylchlorosilane were heated to reflux (54°-91° C.) with the addition of 0.0005 moles of tetra-n-butyl ammonium bromide. Vigorous evolution of HCl was observed. When evolution of gas ceased, the IR spectrum did not show an OH band. When the product was worked up by distillation, pure 1-trimethylsiloxybutane was obtained as distillate.
