Compounds useful as a stabilizer for a variety of organic materials or an intermediate thereof, or as an intermediate of medicines or agricultural chemicals are disclosed, which are cyclohexylamine derivatives represented by the general formula [I]:
wherein R¹ represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an acyl group having 2 to 7 carbon atoms or an arylalkyl group having 7 to 10 carbon atoms; R² represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R³ and R⁴ both represent a hydrogen atom, or one of R³ and R⁴ represents a hydrogen atom and the other represents a group -CH₂-R⁵, or R³ and R⁴ together form a group =CH-R⁵, in which R⁵ represents an unsubstituted or C₁-C₄ alkyl substituted phenyl group, a 2-furyl group, a cyclohexyl group or a 2-tetrahydrofuryl group; X represents an alkylene group having 1 to 3 carbon atoms; and n denotes 1 or 2.
When the compound is used as a stabilizer, it exhibits little bleedout and high photostabilizing effect.
本发明公开了可用作各种有机材料稳定剂或其中间体,或用作药物或农药中间体的化合物,它们是由通式[I]表示的环己胺衍生物:
其中 R¹ 代表氢原子、具有 1 至 4 个碳原子的烷基、具有 2 至 7 个碳原子的酰基或具有 7 至 10 个碳原子的芳烷基;R² 代表氢原子或具有 1 至 4 个碳原子的烷基;R³ 和 R⁴ 均代表氢原子,或 R³ 和 R⁴ 中的一个代表氢原子,另一个代表基团 -CH₂-R⁵,或 R³ 和 R⁴ 共同组成基团 =CH-R⁵、其中 R⁵ 代表未取代的或 C₁-C₄ 烷基取代的苯基、2-呋喃基、环己基或 2-四氢呋喃基;X 代表具有 1 至 3 个碳原子的亚烷基;n 表示 1 或 2。
该化合物用作稳定剂时,渗出少,光稳定效果高。
