Abstract

A találmány tárgya egy eljárás az (I) általános képletű nyerspiperidinszármazékok -, ahol R1-R4 jelentése 1-6 szénatomosalkilcsoport, valamint R1 és R2 és/vagy R3 és R4 együtt egy 2-5szénatomos alkilénláncot képezhet - tisztítására, amit az jellemez,hogy az első lépésben a magas forráspontú komponenseket és adottesetben a vizet a nyers piperidinszármazékokból desztillációvalelkülönítik, a második lépésben 0,01-5 tömegszázalékos mennyiségbenadnak egy redukálószert, az első lépés szerint kapott termék tömegérevonatkoztatva és végül a harmadik lépésben a piperidinszármazékokatdesztillációval nyerik ki.
