The aldoximes are converted by the action of dehydrating agents into nitriles: RCH: NOH-->R C: N+H 2 0.
Acetoxime, (CH 3) 2 C:NOH, melts at 58-59° C. and is readily soluble in water.
Mesityl oxime, (CH 3) 2 C: CH C(: NOH)CH 3, exists in two modifications.
Acetophenoneoxime, C 6 H 5 C(:NOH) CH3, melts at 59° C. In glacial acetic acid solution, on the addition of concentrated sulphuric acid, it is converted into acetanilide.
