从字面看应该是烘箱压力不同
cristina228 发表:Loss on drying is the loss of mass expressed as percent m/m.
干燥失重是描述物质在干燥后减失的量,以质量百分比来表示。
b)"In vacuo": the drying is carried out over diphosphorus pentoxide R, at the pressure of 1.5KPa to 2.5KPa at room temperature.
b)真空干燥:五氧化二磷为干燥剂,常温减压干燥(压力1.5KPa-2.5 KPa)
e)"Under high vacuum": the drying is carried out over diphosphorus pentoxide R at a pressure not exceeding 0.1KPa, at the temperature prescribed in the monograph.
e)高真空干燥:五氧化二磷为干燥剂,按照各论中要求的温度,压力不超过0.1 KPa.
If other conditions are prescribed, the procedure to be used is described in full in the monograph.
除另有规定,程序按照各论中规定进行。
请大家帮忙看看有翻译的不准确不专业的地方,敬请指正!
另外,b)和e)这两种方法到底有什么区别呢?因为我们平时一般都是用烘箱测的。
