Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania kwasu adypinowego który charakteryzuje się tym, że cykloheksano-1,2-diol utlenia się gazami zawierającymi tlen, w polarnym rozpuszczalniku, a reakcję prowadzi się w obecności katalizatora związków metali przejściowych, w ilości 0,01-20% mol., w przeliczeniu na surowiec, kwasu azotowego(V) w ilości 0,1-200% mol. w przeliczeniu na surowiec, w temperaturze 40-200°C w czasie 2-48h. Jako czynnik utleniający stosuje się powietrze, powietrze wzbogacone w tlen lub inny gaz zawierający tlen. Katalizator związków metali przejściowych stosuje się w ilości korzystnie 1% mol. Jako polarny rozpuszczalnik stosuje się kwas octowy, propionowy, wodę lub acetonitryl.The subject of the application is a method for obtaining adipic acid, which is characterized in that cyclohexane-1,2-diol is oxidized with oxygen-containing gases in a polar solvent, and the reaction is carried out in the presence of a catalyst of transition metal compounds, in the amount of 0.01-20% mol ., calculated on the raw material, nitric(V) acid in the amount of 0.1-200% mol. calculated as raw material, at a temperature of 40-200°C for 2-48 hours. Air, oxygen-enriched air or other oxygen-containing gas is used as the oxidizing agent. The transition metal compound catalyst is used in an amount of preferably 1 mole percent. As the polar solvent, acetic acid, propionic acid, water or acetonitrile are used.
