Application | bicyclohexane is an organic compound, which can be used for pharmaceutical and chemical intermediates. |
preparation | a, by catalytic hydrogenation reaction, the boiling point of the impurity 3-cyclohexylcyclohexene contained in the dicyclohexyl ether recovered from the residue of cyclohexanol distillation is 230.4 ℃, the boiling point of 1-cyclohexylcyclohexene is 234.2 °c and the boiling point of cyclohexylidene cyclohexane is 237.6 °c. The boiling point of 1-cyclohexylcyclohexene is 227 °c, the boiling point difference between the impurity compound and dicyclohexyl ether was increased to 242.5 ℃. The reaction temperature of catalytic hydrogenation was 80-220 ℃, the reaction pressure was 1-10 MPa, and the reaction time was 1-6 h, the amount of catalyst is 0.3-10% of the mass ratio of dicyclohexyl ether recovered from cyclohexanol distillation residue, and the stirring speed is 50-600 r/min; B, precise separation of dicyclohexanes and dicyclohexyl ether by vacuum distillation; Separation by batch distillation column, open the vacuum pump, maintain the vacuum of the distillation system 133, gradually heated to 110 ℃, collection of distillation column overhead temperature of 99-100.5 deg C, to obtain the bicyclohexane product, collection of distillation column overhead temperature of 101-102 deg C Fractions to give dicyclohexyl ether product. |
