摘要： A process for the partial dehydration of cyclohexanone oxime by treatment with aqueous solutions of inorganic salts, wherein the crude cyclohexanone oxime is extracted, above its melting point, with a concentrated ammonium salt solution and/or hydroxylammonium salt solution in countercurrent in an extraction column and the salt solution is then separated from the partly dehydrated cyclohexanone oxime, reconcentrated by evaporation and recycled to the oxime dehydration process. The cyclohexanone oxime melt which has been dehydrated to water contents of about 4 to 6% by weight is treated with a heated inert gas above its melting point and the off-gas is washed to remove entrained cyclohexanone oxime.

摘要： A method of separation by fractional crystallization from a liquid mixture in which the liquid mixture is repeatedly passed in turbulent flow through an indirectly cooled crystallization zone, which must be kept full. The liquid remaining after deposition of a layer of crystals on the wall of the crystallization zone is removed, whereupon the surface of the layer of crystals is washed and the crystals are melted by passing a melt of similar compositions to that of the layer of crystals through the crystallization zone. During crystallization the melt is maintained at the temperature of crystallization and crystallization is stopped when the frozen fraction is from 70 to 98%.
