    • An O-substituted hydroxylamine having the following general formula : R -CHX-O-NH , wherein X is hydrogen or an alkyl; and R is an unsubstituted or substituted phenyl, thienyl, furanyl, pyrrolyl or -CR =C R ; wherein R , R and R are hydrogen, halogen or alkyl. The O-substituted hydroxylamine exhibits at least one property selected from the group consisting of- essentially free of hydroxylamine; essentially free of any solvent; a water content of between about 0% to 90% by weight; and a high strength (as measured by mole of the 0-substituted hydroxylamine per gram of sample) of between about 0.5 to 3.3-fold as much as a 40% O-substituted hydroxylamine salt solution, by weight. The 0-substituted hydroxylamine further comprising at least one additional property selected from the group consisting of: a purity of between about 98% to 100%, based on gas chromatographic area; and a purity drop of less than about 1.2% after 78 days at 40°C when the O-substituted hydroxylamine has a concentration of about 85% in water, based on gas chromatographic area. The O-substituted hydroxylamine is at least one isomer selected from the group consisting of cis, trans and a mixture thereof. The O-substituted hydroxylamine may also be reacidified to an O-substituted hydroxylamine salt free of hydroxylamine.
    • 具有以下通式的O-取代羟胺:R 1 -CHX-O-NH 2,其中X是氢或烷基; R 1是未取代或取代的苯基,噻吩基,呋喃基,吡咯基或-CR 2 = C 3 R 4; 其中R 2,R 3和R 4是氢,卤素或烷基。 O-取代的羟胺显示出至少一种选自基本上不含羟胺的性质; 基本上不含任何溶剂; 水含量在约0重量%至90重量%之间; 和高强度(按每克样品的0-取代羟胺的摩尔量测得)的重量比为40%O-取代的羟胺盐溶液的约0.5-3.3倍。 所述O-取代的羟胺还包含至少一种选自以下的附加性质:基于气相色谱面积的约98%至100%的纯度; 并且当取代羟胺在水中的浓度约为85%时,基于气相色谱面积,在40℃下78天后的纯度下降小于约1.2%。 O-取代的羟胺是选自顺式,反式和其混合物中的至少一种异构体。 O-取代的羟胺也可以再酸化成不含羟胺的O-取代的羟胺盐。
