物性数据求助? 这个东西的很多数据恐怕目前没定论,如果您不在乎有争议数据的话…… 而且说实话,有些性质鄙人确实没接触过,不怎么懂,理解和翻译上可能都是有误的 您最好是看英文原文自己翻译 epa的资料是这么写的 http:///oppthpv/quicksearch.display?pchem=100226 熔点melting point study1 65℃;study2 65.5-67℃;study3 172℃(按说明这个好像是软件理论计算结果) 补充,cas资料是65℃;其他也有63-66℃的说法,可能和纯度、异构体问题有关? 沸点boiling point study1 300℃(压力为760mm hg柱);study2 436℃(软件计算结果) 补充,cas资料是221℃ (压力为10mm hg柱);另有一资料是206℃ (压力为15mm hg柱) 蒸汽压vapor pressure 0.00000000584 mm hg柱(温度为25℃,软件计算结果) 分配系数partition coefficient 6.73 (计算结果) 水中溶解度water solubility 0.0548 mg/l(温度为25℃,上面的分配系数就是根据这个实验结果计算的) 光降解photodegradation 半衰期 2.24小时(软件计算结果) (结果说明有一条,曾经有个该物质水溶液的光降解实验,半衰期达到35天) 水中稳定性stability in water 无研究结果 原文说明:酚类没有水解的官能团。软件无法进行理论计算。 transport between environmental compartments fugacity/dist 这个不太清楚是什么,好像是在环境中不同相间的运输扩散? environmental compartment percentage of test substance air 1.95e-5 soil 97.7 water 0.021 suspended sediment 0.068 fish 0.0055 sediment 2.17 temperature: 25 °c level of multi-media model: i model input (water solubility): 0.0548 mg/l model input (vapor pressure): 7.8e-7 pa model input (log kow): 6.73 model input (melting point): 65 deg c 生物降解biodegradation the program predicts:(软件计算结果) primary biodegradation in weeks ultimate biodegradation in months. this material is considered to be inherently biodegradable, and would aerobically biodegrade very slowly. 水生脊椎动物的急性毒性 acute toxicity to aquatic vertebrates lc50 (96hr) 0.059 mg/l chv (30 day) 0.008mg/l chv (90 day) 0.003 mg/l remarks: log kow used 6.73 (calculated value) conclusions estimated lc50 (96hr) for the test substance was found to be 0.059 mg/l. 水生无脊椎动物的急性毒性 acute toxicity to aquatic invertebrates lc50 (48hr) 0.21 mg/l chv (21day) 0.007 mg/l remark: log kow used 6.73 (calculated value) conclusions estimated lc50 (48hr) for the test substance was found to be 0.21 mg/l. 水生植物的急性毒性 acute toxicity to aquatic plants ec50 (96hr) 0.011 mg/l chv (96hr) 0.016 mg/l remark: log kow used 6.73 (calculated value) conclusions estimated ec50 (96hr) for the test substance was found to be 0.011 mg/l. 水生植物慢性毒性 chronic aquatic vertebrate toxicity lc50 (96hr) 0.059 mg/l chv (30 day) 0.008mg/l chv (90 day) 0.003 mg/l remarks: log kow used 6.73 (calculated value) conclusions estimated lc50 (96hr) for the test substance was found to be 0.059 mg/l. 水生无脊椎动物慢性毒性 chronic aquatic invertebrate toxicity lc50 (48hr) 0.21 mg/l chv (21day) 0.007 mg/l remark: log kow used 6.73 (calculated value) conclusions estimated lc50 (48hr) for the test substance was found to be 0.21 mg/l. 后面还有皮肤刺激性skin irritation的实验数据 您自己看吧查看更多
