Abstract (en)

1. Claims (for the Contracting States : BE, CH, DE, FR, GB, IT, LI, NL) The use of 2-methylpentanoic acid esters corresponding to the following formula see diagramm : EP0098791,P6,F3 in which R is a branched or carbocyclic radical corresponding to the formula see diagramm : EP0098791,P6,F4 wherein R**1 = H, CH3 R**2 = H, CH3 , C2 H5 R**3 = C2 H5 , n-C3 H7 , CH(CH3 )2 , n-C4 H9 with the proviso that only one of the radicals R**1 , R**2 can represent H, or wherein R**1 , R**2 = (CH2 )n , n = 3 or 4 R**3 = H as perfumes. 1. Claims (for the Contracting State AT) The use of 2-methylpentanoic acid esters corresponding to the following formula see diagramm : EP0098791,P7,F3 in which R is a branched or carbocyclic radical corresponding to the following formula see diagramm : EP0098791,P7,F4 wherein R**1 = H, CH3 R**2 = H, CH3 , C2 H5 R**3 = C2 H5 , n-C3 H7 , CH(CH3 )2 , n-C4 H9 with the proviso that only one of the radicals R**1 , R**2 can represent H, or wherein R**1 , R**2 = (CH2 )n , n = 3 or 4 R**3 = H as perfumes.

Abstract (de)

Die beanspruchten 2-Methylpentansäureester sind mit Ausnahme des 2-Methylpentansäure-2-methylpentylesters neue Verbindungen, die wertvolle Riechstoffe mit blumigen, fruchtigen, würzigen, holzigen Geruchsnoten und sehr guter Haftfestigkeit darstellen. Man gewinnt die Verbindungen durch Veresterung von 2-Methylpentansäure mit einem der allgemeinen Formel entsprechenden verzweigten oder carbocyclischen Alkohol.
