Chemistry and technology of special-purity trimethyl alkoxysilanes

Technology of high-purity trimethylalkoxysilanes was developed. To rule out the lability of chemical forms of trace impurities, an additional stage of the ion-exchange purification of the starting alcohols is introduced into the classical scheme of synthesis of trimethyl alkoxysilanes and deep recti...

Description
Summary:Technology of high-purity trimethylalkoxysilanes was developed. To rule out the lability of chemical forms of trace impurities, an additional stage of the ion-exchange purification of the starting alcohols is introduced into the classical scheme of synthesis of trimethyl alkoxysilanes and deep rectification purification. To raise the yield of the final product, the stage of azeotropic distillation with azeotrope-forming components is introduced. Construction materials are chosen and a gas-chromatographic analysis of the impurity composition of trimethylalkoxysilanes was made. The development was performed with the use of CALS technologies.
