发帖数: 95 | 4 我在为含氟的丙烯酸酯/丙烯酰胺类高分子寻找good solvent,发现trifluoroacetic
acid (TFA)的溶解能力特别强，很好用。可是，高分子（白色粉末）溶解于新鲜的TFA
之后溶液由无色透明慢慢变为淡黄色透明。
是不是因为TFA是强酸有所谓的发烟现象？浓盐酸就是淡黄色，因为含有少量杂质Cl2
。另外， 含卤素或含硝基的化合物容易变颜色,是少量变质导致的吗？
谢谢！
p.s.
查到有这么一句：“olutions of proteins in trifluoroacetic acid prepared in
vacuo
are clear and colourless; on exposure to air, a purple colour develops.”不
解中···
