Williams, D. B. G. and M. Lawton (2010). "Drying of Organic Solvents: Quantitative Evaluation of the Efficiency of Several Desiccants." The Journal of Organic Chemistry: null-null. Various commonly used organic solvents were dried with several different drying agents.Agloveboxbound coulometric Karl Fischer apparatus with a two-compartment measuring cell was used to determine the efficiency of the drying process. Recommendations are made relating to optimumdrying agents/conditions that can be used to rapidly and reliably generate solvents with low residual water content by means of commonly available materials found in most synthesis laboratories. The practical method provides for safer handling and drying of solvents than methods calling for the use of reactive metals, metal hydrides, or solvent distillation.
从题目与摘要上了解到，通过水份测定仪（coulometric Karl Fischer ）从定量上来评定不同的如活性金属、金属氢化物、蒸馏等干燥方法的去水效果的
再看其背景：这前的文献发现没有人对干燥溶剂进行定量的公布（我想大家思维都一样，这么平常的操作，每个人都会的没有必要去发表说明，区别所以看来活还是要做的细致）。借助于coulometric Karl Fischer titrations这个仪器来采集足够的数据，建立易操作，安全，结果易再现的方式去干燥常用的溶剂，推荐日常的使用
