摘要
Abstract
Methane-siliconic polymerization,a type of byproduct of the trichlorosilane hydrolyzate in the preparation of the organic silicon monomer,which as main raw material react with a hydrated aluminum ion to prepare methyl aluminosilicate.The optimum condition are as follow:the activation temperature of methylated silanol is 350 ℃, the mass ratio with sodium hydroxide is 1:1.3, the dissolving solvent is water-ethanol with volume ratio of 4:1,dissolution temperature is 80℃in water bath;the soluble silicon solution was added dropwise to the hydrated aluminum ion solution under stirring conditions at 30℃,the pH value is control led in the range of 10 to 13, then we get the title methyl aluminosilicate.Further characterization are including white meter,SEM,X-ray spectrum,TGA,IR spectroscopy,XRD for the product.Analysis results indicate that the product is an ultrafine white powder with good thermal stability.关键词
