    Dye Release Compound and One-Equivalent Coupler
    染料释放化合物及一当量成色剂浅谈
    2. One-pot deprotection-oxidation-Wittig reaction of silyl ethers in the presence of an equivalent of acetic acid, MnO2 and stable Wittig reagents generated the corresponding a, p-unsaturated esters.
    2.在一当量的醋酸和稳定的Wittig试剂存在下,MnO_2作为氧化剂,硅醚经历脱保护—氧化—Wittig反应,“一锅法”转化成α,β-不饱和酯。
    Suppose that the interaction of NaOH with surface acidic sites in aqueous solution occurs according to the following stoichiometric relation: one mole Bronsted acid reacts with one mole of NaOH, and one mole of Lewis acid uses up two moles of NaOH, while both one mole Bronsted and one mole Lewis acids react with one mole of butylamine in nonaqueous solution, therefore, the surface concentration of both Lewis and Bronsted sites can be determined by butylamine titration and NaOH neutralization.
    中和同样数量的酸性中心所消耗NaOH的当量数比正丁胺多,其差值与Lewis酸的含量有关。 假定NaOH与LaHY表面上酸性中心作用的机理为:一当量Bronsted酸与一当量NaOH作用,而一当量Lewis酸消耗两当量NaOH,则可借助正丁胺滴定和NaOH中和法测定Bronsted酸和Lewis酸的含量。
