摘要
合成了4种新的单异丙基铝酸酯,分子量测定表明它们在苯中的缔合度为1.6~1.8,红外光谱推定存在铝配位数为5和6的二种双体,化合物的水解及热分解稳定性比短链的单异丙基铝酸酯稳定.比较讨论了这类化合物与相应的单异丙基二核铝酸酯在结构和性质上的异同.
Compounds of Al(OP)[O_2P(OR)_2]_2. Al(OP)[O_2P(R)(OR)]_2 and Al(OP)(O_2CR')_2(Where R=C_4H_9CH(C_2H_5)CH_2, R'=C_8H_17CH=CHC_7H_.4- or C_17H_35)weresynthesized by reactions of aluminium isopropoxide with relevant acids. Apparentmolecular weights obtained by vapor pressure studies showed that degrees ofpolymerization of the compounds in bezene were between 1.6 and 1.8.Their IR.spectra indicated that they existed in two forms of dimers. Their hydrolysis rates weremeasured by means of homogeneous phase hydrolysis. Themal stability in air obtainedby TGA showed that the compounds were quite stable.
