A method for the purification of nitromethane, which is present in the mixture is present with elevated nitroalkanes

摘要

Nitromethane is recovered from mixtures with higher nitroalkanes by adding to said mixtures sufficient water and C6- 8 alkane or cycloalkane to form an azeotropic mixture with said nitromethane, and heating the mixture to distil off said azeotrope. The said azeotrope condenses into three layers, the lowest of which contains the nitromethane with minor amounts of water and alkane. The water and alkane may be removed by further distillation up to 101.5 DEG C.
