  ethyl 2-[5,11-bis(2-ethoxy-2-oxoethyl)-15-nitro-14-(2,4,6-trinitroanilino)-2-oxa-5,8,11-triazabicyclo[10.4.0]hexadeca-1(12),13,15-trien-8-yl]acetate 在 lithium hydroxide 作用下， 以 1,4-二氧六环 、 水 为溶剂， 反应 4.0h， 生成 2-[5,11-Bis(carboxymethyl)-15-nitro-14-(2,4,6-trinitroanilino)-2-oxa-5,8,11-triazabicyclo[10.4.0]hexadeca-1(12),13,15-trien-8-yl]acetic acid

  名称：

  A novel 12-membered triazaoxamacrocycle-N,N',N''-triacetic acid indicator for colorimetric determination of calcium

  摘要：

  The synthesis of a novel chromogenic triazaoxamacrocycle bearing three acetic acid groups and a 2,4,6-trinitroanilino chromophore, for generation of a spectrophotometric response, is described. As determined by potentiometric titration conducted in water, tetraionizable chromoionophore 4 forms a rather weak 1:1 complex with calcium (K(s) = 9.5 X 10(2) M-1) but exhibits very high selectivity for Ca2+ over Mg2+ at neutral pH. Cation responses at pH 7.0, 8.0, 9.0, and 10.0 are determined. The response of 4 to calcium is linear from 2 x 10(-5) to 1 x 10(-4) M Ca2+.
