Synthesis of 2-Hydroxy-3-(Methyl­cyclo­hexenyl-Isopropyl)-5-Methylbenzyl­amino­ethylnonyl Imidazolines - The Thermostabilizers to Polypropylene

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.
