(METHOXYMETHYL)TRIMETHYLSILANE Usage And Synthesis

Purification Methods

It forms an azeotrope with MeOH (b 60o). If it contains MeOH (check IR for bands above 3000cm-1), then wash with H2O and fractionate. A possible impurity could be chloromethyl trimethylsilane (b 97o/740mm). [Speier J Am Chem Soc 70 4142 1948, Beilstein 4 III 1844.] It is an IRRITATING FLAMMABLE liquid.
