摘要： The present invention provides a method for obtaining high purity chlorosilanes from chlorosilanes containing boron impurities and phosphorus impurities. On the basis of the finding that solid by-product formation in the purification of chlorosilanes by adding an aromatic aldehyde results from a catalytic reaction by iron ions or rust-like iron, a Lewis base having a masking effect is added to chlorosilanes. Examples of the Lewis base include a divalent sulfur-containing compound and an alkoxysilane. The divalent sulfur-containing compound is preferably a compound represented by the formula: R—S—R′ (wherein R is a hydrocarbon group or a carbonyl group; and the sum of the carbon atoms in R and R′ is 7 or more), and the alkoxysilane is preferably a compound represented by the formula: RxSi(OR′)4-x (wherein R and R′ are each an alkyl group having 1 to 20 carbon atoms).

摘要： This method for purifying chlorosilanes includes: introducing oxygen (O2) into the chlorosilanes containing a boron impurity and a phosphorous impurity in the presence of an aromatic aldehyde; treating the chlorosilanes to convert the impurities into high boiling compounds at the same time; and subjecting the chlorosilanes after having been treated to a distillation process or the like to separate the high boiling compounds of boron and phosphorous from the chlorosilanes. The high boiling compounds produced through the above described treatment are not decomposed into low boiling compounds by the heat applied after the high boiling compounds having been produced, so that the high boiling compounds can be easily separated from the chlorosilanes through treatment such as distillation. Accordingly, the boron impurity and the phosphorous impurity can be removed with a single process.

摘要： A (meth)acryloxy-bearing alkoxysilane is isolated and purified to a high purity by distilling a reaction solution containing the (meth)acryloxy-bearing alkoxysilane in a thin-layer distillation device at a temperature of 90-160° C. and a vacuum of 1-15 mmHg. The resulting alkoxysilane product does not give rise to the quality problem that the product will gradually whiten during storage owing to contact with air. The occurrence of self-polymerization of the alkoxysilane is restrained.
