1. 4 - Cyclohexane dimethyl mellow two different caprylate synthesis process (by machine translation)

The invention relates to a synthetic esters, in particular to a method for synthesizing 1, 4 - cyclohexane dimethyl mellow two different caprylate. The preparing step comprises: at superatmospheric pressure, 250 - 400 °C temperature, in the reaction kettle to join the phenyl acetic acid with (4 - methyl cyclohexyl) methanol, after the stirring, the full reaction, and to get the acetic acid-methyl (4 - methyl cyclohexyl); to a reaction system by adding Zn - Ge/C catalyst, hydrogen, hydrogen is charged into the hydrogenation reaction, the hydrogenation reaction period, control hydrogenation rate, the reaction kettle maintained at a temperature of 100 - 150 °C and pressure is maintained in the 1 - 3 mpa, after the end of the hydrogenation reaction, cooling to 90 - 100 °C, and slowly opening the exhaust port, to obtain 1, 4 - cyclohexyldimethanol; step a preparation of 1, 4 - cyclohexyldimethanol with unhydride added in a reaction vessel, then adding super strong acid catalyst SO4 2 - /TiO2 /Ce, the reaction temperature is 100 - 200 °C, reaction 5 - 15 h, reaction end-stop heating to obtain crude; post treatment of the product. This synthetic route is suitable for industrial production. (by machine translation)

PROCESS FOR THE PREPARATION OF 1,4-CYCLOHEXANEDIMETHANOL

Disclosed is a process for the preparation of 1,4-cyclohexanedimethanol from terephthalic acid. Terephthalic acid is esterified with (4-methylcyclohexyl)methanol and the terephthalate ester hydrogenated to 1,4-cyclohexanedimethanol in a 2-stage process. The (4-methylcyclohexyl)methanol that is formed during the hydrogenation step is recycled to the esterification reaction. After removal of the (4- methylcyclohexyl)methanol from the crude hydrogenation product, the 1,4- cyclohexanedimethanol product can be recovered and purified by a phase separation and distillation.
