摘　　要：建立摇瓶法测定1,5-戊二胺的正辛醇/水分配系数分析方法。气相色谱法测定正辛醇中1,5-戊二胺含量,离子色谱法测定水相中1,5-戊二胺含量。当正辛醇与水体积比为2:1时,lgPow为-0.38;体积比为1:1时,lgPow为-0.26;体积比为1:2时,lgPow为-0.24;lgPow平均值为-0.3。该方法简单可靠,符合OECD 107要求,适用于1,5-戊二胺的正辛醇/水分配系数的测定。The analytical method for determination of the n-octanol/water partition coefficient of 1,5-diaminopentane by shake flask method was established. The 1,5-diaminopentane in n-octanol was determined by gas chromatography. The 1,5-diaminopentane in water was determined by ion chromatography. When the volumetric ratio of n-octanol/water was 2：1, lgPow was-0.38, the volumetric ratio of n-octanol/water was 1：1, lgPow was -0.26, the volumetric ratio of n-octanol/water was 1：2, lgPow was -0.24. The average value of lgPow was-0.3. The method was simple and reliable, conformed to the requirement of OECD 107, and could be suitable for determination of the n-octanol/water partition coefficient of 1,5-diaminopentane.
