2-PHENYL-INDOLE DERIVATIVES AND PROCESS FOR PREPARING THE SAME

摘要

2-phenyl-indole derivatives having the following general formula: (I) wherein R represents a phenyl group, amino group, optionally substituted by an acetyl or benzoyl group, a mercapto group, optionally substituted by a branched-or straight-chain alkyl group containing from 1 to 12 carbon atoms or by a cyclohexyl radical, a carboxyl radical, a group R1O-, wherein R1 represents an atom of hydrogen, an isopropyl, carboxymethyl, carbethoxymethyl, carbethoxyisopropyl, acetyl, docosanoyl, benzoyl, benzyl, or allyl radical or a branched-or straight-chain alkyl radical containing from 6 to 12 carbon atoms. The derivatives of formula(I) have been found to be particularly valuable as stabilizers of polymers and co-polymers intended to be formed by extrusionmoulding , blow-moulding and calendering, mainly but not solely with a view to manufacturing containers for food and drink, such as, for example, bottles for wine, oil, vinegar and mineral water.
