Crystal solvent

WebSep 4, 2012 · Rinse the crystals with the minimum amount of a cool solvent in which the compound is insoluble and remove this solvent as before. If the compound is air stable, remaining excess solvent can be removed by blotting the crystals on a piece of clean tissue paper. The crystals should be handled carefully with either tweezers or a spatula. http://www.whxb.pku.edu.cn/EN/10.3866/PKU.WHXB202402242
