DEFINITION

Classification: 558/314

(under subclass 308) Processes wherein there is utilized nitryl halide, nitrosyl halide, or compounds containing one of the groups HCH=NO- or HHNO- (wherein substitution may be made for hydrogen only.)

(1) Note. Nitryl halide is NO2X, where X is halogen.

(2) Note. Nitrosyl halide is NOX, wherein X is halogen.

(3) Note. Examples of compounds containing the group HCH=NO- are oximes, oxime ethers and oxime esters.

(4) Note. Examples of compounds containing the group HHNO- are hydroxylamine, hydroxylamine salts, hydroxyylamine ethers and hydroxylamine esters.
