Storability of molten cyclohexanone oxime |
摘要 |
The storability of molten cyclohexanone oxime containing 0.5-15% by weight of cyclohexanone and 1-8% by weight of aqueous ammonium bisulfate solution is improved by washing the molten cyclohexanone oxime with a 10-42% strength by weight aqueous ammonium sulfate solution and maintaining a pH of 4.5-5.8.
