    Síntesis y caracterización espectroscópica del cloruro de oleoilo
    (2007) Alfonso Rivas Gil; Cristóbal Lárez Velásquez; H B Alí Bahsas
    Oleoyl chloride was synthetized using a recently distilled at reduced pressure oleic acid and thionyl chloride as starting materials. Acyl halide was vacuum distilled and later on characterized by FTIR, 1 H-RMN and 13 C- RMN spectroscopy. Additional experiments of 1 H-COSY, HSQC and HMQC were carried out, which allowed to assign unquestionably the structure of the synthesized material. Keywords: oleoyl chloride, oleic acid, 1 H-
