  • O-(3-chloropropenyl) hydroxylamine free base
    Patent number: 7214825
    Abstract: An O-substituted hydroxylamine having the following general formula: R1—CHX—O—NH2 wherein X is hydrogen or an alkyl; and R1 is an unsubstituted or substituted phenyl, thienyl, furanyl, pyrrolyl or —CR2?CR3R4; wherein R2, R3 and R4 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 O-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 O-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.
