| 产品介绍 |
application： Perrhenic acid solution (HReO4) can be used in dehydrations of oximes, amides, and urea. HReO4 can also catalyze azeotropic dehydration of syn- or anti-aldoximes to yield corresponding nitriles. In combination with tertiary arsines, it gives a versatile catalytic system for epoxidation of alkenes with hydrogen peroxide. It is also used to prepare highly conducting and superconducting synthetic metals. |
