油水分配系数/LogP:

LogP值指的是某物质在正辛醇/水两相体系中的分配系数的对数值,反映了物质在油水两相中的分配情况。其中、LogP值越大,说明该物质越亲油;反之,LogP值越小,则说明该物质越亲水。

生产制备方法及用途展开↓

合成制备方法


将溴化锂溶液加热到200℃,蒸发浓缩,于190℃下冷却得颗粒状一水物沉淀。如在159℃凝固,几乎全部形成一水物。也可在44℃以上于过饱和溶液中析晶。

用途


是一种高效的水蒸气吸收剂和空气湿度调节剂。54%55%浓度的溴化锂可用作吸收式制冷剂。在有机化学中用作氯化氢脱除剂,有机纤维(如羊毛、头发等)膨松剂。医药上用作催眠剂和镇静剂。此外,还用于感光工业、分析化学以及某些高能电池中的电解质和化学试剂。
