摘　　要：运用电导法测定了体积比为38%乙醇溶液中β-环糊精(简称β-CD)对脂肪酸酯水解速率常数的影响,推导并检验了定量表达酯水解速率常数(k)与β-CD浓度(M)关系的数学表达式:k=k′/(1+AM),得出了β-CD对脂肪酸酯水解反应起禁阻作用的结论.The effects of β-CD on hydrolysis rate constants(k) of fatty acid esters from 38 %(V/V) ethanol solution were studied by conductometry.The quantificational mathematic equation,k=k′/(1+AM),between hydrolysis rate constants(k) of esters and the concentration of β-CD(M) was deduced.The result showed that β-CD inhibited the hydrolysis reaction of fatty acid ester.
