Trimethylsilylation of Calcium Silicate
The Journal of the Society of Chemical Industry, Japan, 1971 ケイ酸カルシウムの水熱合成条件の確立とケイ素無機高分子の利用面を開発するため基礎研究を行なった。各種のケイ酸カルシウムについて, レンツのトリメチルシリル化法を採用し, 元素分析, 分子量測定, 赤外吸収分析を行なった結果, 不溶性三次元ブロック構造, 可溶性揮発性の線状構造, 可溶性不揮発性梯形構造の三つのポリシリケート誘導体を分離した。この結果, 水熱合成反応で低温短時間から得られたものを原料として生成したポリシリケートの分子量は小さく, 高温長時間からのものは大きい分子量をもつことが判明した。従って, ケイ酸カルシウム製造時の水熱反応段階でシロキサン鎖の縮合成長反応が順次進行しているものと考えられる。また, 粘土を添加したトバモライトは, Si-O-Siのシロキサン鎖が Si:Al=5～6 ...
