Compounds useful as a stabilizer for a variety of organic materials of an intermediate thereof, or as an intermediate of medicines or agricultural chemicals are disclosed, which are cyclohexylamine derivatives represented by the general formula [I]: ##STR1## wherein R.sup.1 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; R.sup.2 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R.sup.3 and R.sup.4 both represent a hydrogen atom, or one of R.sup.3 and R.sup.4 represents a hydrogen atom and the other represents a group --CH.sub.2 --R.sup.5, or R.sup.3 and R.sup.4 together form a group .dbd.CH--R.sup.5, in which R.sup.5 represents an unsubstituted or C.sub.1 -C.sub.4 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.
本发明公开了一种用作各种有机材料的稳定剂或其中间体,或用作药物或农药化学品的中间体的化合物,其为由一般式[I]表示的环己胺衍生物:##STR1## 其中R.sup.1代表氢原子、具有1至4个碳原子的烷基基团、具有2至7个碳原子的酰基基团或具有7至10个碳原子的芳基烷基基团;R.sup.2代表氢原子或具有1至4个碳原子的烷基基团;R.sup.3和R.sup.4都代表氢原子,或R.sup.3和R.sup.4中的一个代表氢原子,另一个代表--CH.sub.2--R.sup.5基团,或R.sup.3和R.sup.4一起形成.dbd.CH--R.sup.5基团,其中R.sup.5代表未取代或C.sub.1-C.sub.4烷基取代的苯基团、2-呋喃基团、环己基团或2-四氢呋喃基团;X代表具有1至3个碳原子的烷基基团;n表示1或2。当该化合物用作稳定剂时,表现出较少渗漏和高光稳定效果。
