摘要
有毒有机化合物在水中的溶解度(WS)及正辛醇/水分配系数(K_(ow)),是描述其在环境中行为的两个重要物理化学参数。本文用溶解度平衡曲线法和振荡法,测得单甲脒在水中的溶解度为21.8±1.3mg/1(25℃),其在正辛醇/水中的分配系数lgK_(ow)为2.92±0.06。
Water solubility and n-octanol/water partition coefficient of pesticide N-(2,4-dimethylphenyl)-N'-methyl amidineCDMA) were studied by using solubility curve method and shake flask method, respectively. The solubility of DMA in water and the n-octanol/water partition coefficient(lgKow) were found to be 21.8± 1.3mg/l(25℃) and 2.92±0,06, respectively.
