Abstract
2-hydroxy-3-(methylcyclohexenyl-isopropyl)-5-methylbenzylaminoethylnonylimidazolines were synthesized by the interaction of 2-(methylcyclohexynylisopropyl-4-methylphenols and aminoethylnonylimidazoline. Aminocompounds are purified from cycloalkylphenol by transferring them to hydrochloride salt. Further, aqueous solution of the hydrochloric acid amine salt is treated with a concentrated solution of NH4OH and free aminecompounds are isolated. The resulting amine is separated from water by benzene extraction. After benzene distillation, the residue is undergone to distillation under vacuum. Its physico-chemical characteristics and purity of the products are determined. The obtained products are tested as the thermostabilizers to polypropylene.
