摘　　要：在金属表面硅烷化处理的工业过程中,测定硅烷工作液的水解度是确定硅烷有效利用率和建槽过程中浓缩液稀释倍数的重要依据。以双-(3-三甲氧基硅基丙基)胺(BAS)和乙烯基三乙酰氧基硅烷(VTAS)的混合硅烷体系为研究对象,通过分光光度法测定了不同稀释程度下和不同BAS/VTAS配比条件下,混合体系中主要成分BAS的水解度。结果表明:加水稀释和提高BAS在混合硅烷中的比例,均能够进一步提高BAS的水解程度。During silanes surface treatment, the hydrolysis degree is important operating parameters for the effective utilization of silanes and dilution multiple of concentrated solution in the building of silane bath. The water soluble mixtures of bis[ trimethoxysilylpropyl ] amine （BAS） and vinyhriacetoxysilane （VTAS） were choose as raw materials. The influences of dilution and the ratio of BAS on the hydrolysis degree of BAS were studied by spectrophotometer method. The results show that the dilution and increasing of the ratio of BAS are both beneficial to the further hydrolysis of BAS.
