先谢谢了有专利文献： The reaction mixture was allowed to stir under reflux conditions for approximately thirty minutes. After the thirty minute time period, the heating mantle was shut off to allow slow cooling of the reaction mixture with stirring. The reaction mixture was allowed to cool with stirring overnight (about 18 hours). As the reaction mixture cooled, the product crystallized out as large "yellowish" hexagonal prismatic crystals. The mixture was allowed to stir under ambient conditions for one hour. The crystals were spread over glass trays and allowed to dry under ambient conditions to a Karl Fischer value of about 9.6%. 我是这样操作的，反应液在搅拌作用下回流30min，然后关掉热源继续叫吧，自然冷却到室温。结果我 是生成了针晶，和文献文献描述不一样！为什么？再一个文献说在室温干燥，如何操作？ |
