摘要： A process for the purification of fluoroalkanesulfonate salt comprising (a) contacting a mixture of said salt and an inorganic salt contaminant with a solvent to selectively dissolve said fluoroalkanesulfonate salt in solution, and (b) isolating the solution, to yield a fluoroalkanesulfonate salt containing less than 500 micrograms of inorganic salt contaminant per gram of fluoroalkanesulfonate salt, or containing less than a maximum of 0.3% by weight of individual solvent.

摘要： Aromatic compounds such as o-xylene are selectively nitrated by nitric acid in the presence of polyphosphoric acid and a large pore, acidic zeolite or a large pore, hydrophobic molecular sieve. This is an environmentally friendly, commercially viable, high conversion process for the selective nitration of aromatic compounds in the para position.

摘要翻译： 芳族化合物如邻二甲苯在多磷酸和大孔，酸性沸石或大孔疏水分子筛存在下，被硝酸选择性硝化。 这是一种环保，商业上可行的高转化率方法，用于选择性硝化对位芳族化合物。
