Zusammenfassung:An esterification of the mix of phenols is described, containing 30 to 50 mass % of monoisopropylphenols, 2 to 10 mass % of diisopropylphenol, between 0.2 and 2 mass % of triisopropylphenols and 30 to 70 mass % of phenol with phosphoryl (tri)chloride in a discontinued and a continued manner originated by a cascade of through-flow mixed reactors with a range of temperatures between 80 to 180 degrees Celsius. This method of esterification is possible to be applied in the organic technology when preparing mixed triaryl phosphates with a wide range of applications utilising the properties of individual isomers and/or mixes.
