    • The present invention provides antioxidants made of an aromatic hydroxyamine derivative having a structure represented by the general formula (I): wherein R1, R2 and R3 are each independently a hydrogen atom or an alkyl group having 1 to 20 carbon atoms; X is a hydrogen atom or an OH group; Y is a hydrogen atom or an NHR1 group; A is a direct bond, —O—, —NH—, —SO2—, —CH2— or —C(CH3)2—, and when an OH group and an NHR1 group are introduced to a unilateral benzene ring, these groups are respectively bonded to adjacent positions of the benzene ring; and n is 0 or 1 with the proviso that when n is 0, R1 is not a hydrogen atom, as well as bisaminophenol derivatives represented by the above general formula (I) wherein n is 1; R2 and R3 are each a hydrogen atom; X is an OH group; Y is an NHR1 group; A is —C(CH3)2—; and R1 is isopropyl, isobutyl or isohexyl. The aromatic hydroxyamine derivatives having a structure represented by the general formula (I), in particular, the bisaminophenol derivatives as novel substances, exhibit an excellent oxidation-inhibiting property, and are usable as antioxidants or polymerization inhibitors.
    • 本发明提供由具有由通式(I)表示的结构的芳族羟胺衍生物制成的抗氧化剂:其中R 1,R 2和R 3各自独立地为氢原子或具有1至20个碳原子的烷基; X是氢原子或OH基团; Y是氢原子或NHR1基团; A是直接键合-O - , - NH - , - SO 2 - , - CH 2 - 或-C(CH 3)2 - ,当将OH基团和NHR 1基团引入单侧苯环时, 分别结合到苯环的相邻位置; n为0或1,条件是当n为0时,R 1不是氢原子,以及由上述通式(I)表示的二氨基苯酚衍生物,其中n为1; R2和R3各自为氢原子; X是OH基; Y是NHR1基团; A是-C(CH 3)2 - ; 并且R 1是异丙基,异丁基或异己基。 具有由通式(I)表示的结构的芳族羟胺衍生物,特别是作为新物质的二氨基苯酚衍生物,表现出优异的氧化抑制性,可用作抗氧化剂或聚合抑制剂。
