Oxidation of Perfumery Secondary Alcohols by Nicotinium Dichromate; A Kinetic Study

Chemical kinetics is mainly concerned with studying the factors that change reaction rate and response mechanism. The present paper investigates law for reaction, order of secondary alcohols(menthol) compares it to other alcohols like Borneol Isoborneol. Diagnose product oxidation reaction. perfumery [menthol], [Borneol], [Isoborneol] by NDC have been studied in aqueous acetic acid medium at 303K. were converted corresponding carbonyl compounds. concerning [Subs], [Oxi], [H+] ions concentration found be one. decrease dielectric constant enhances ionic strength has no significant effect on reactivity response; does not induce polymerization Acrylonitrile, indicating absence free radical pathway. added Mn2+ show was slightly increasing order. four different temperatures Eyring equation used calculate thermodynamic parameters Gibbs energy (ΔG#), entropy (ΔS#), enthalpy (ΔH#). On increase temperature increased abruptly. There a (ΔS#) system indicated value which showed some restriction freedom movement molecules. It observed follows Menthol<Isoborneol<Borneol. Based steric factors, structure, isomeric characteristics under investigation.
