This paper reports solubility and partition coefficient data for the structurally similar pesticides, fenvalerate and cypermethrin, measured by UV spectrophotometry in binary mixtures of methanol and water at different temperatures. The solubility of both pesticides is much higher in methanol than in water at all temperatures. Partition coefficients were also measured between water+heptanol immiscible mixtures at 298.15K, and these data show a decrease with increasing composition of methanol in water.
本文报道了通过紫外分光光度法在不同温度下甲醇和水的二元混合物中测得的结构相似的农药氰戊菊酯和氯氰菊酯的溶解度和分配系数数据。在所有温度下,两种农药在甲醇中的溶解度均远高于在水中的溶解度。还在298.15K下测定了水 + 庚醇不混溶混合物之间的分配系数,这些数据表明随着水中甲醇组成的增加而降低。
