Oxidation of cyclohexane in air produces cyclohexanone and cyclohexanol in cyclopol-bis process along with waste water stream containing valuable carboxylic acids. Process is devised in this manuscript to prepare complex polyol ester base oil by utilizing the waste water. The waste water stream from the cyclohexane oxidation process of Gujarat state fertilizers and chemicals ltd. has been vacuum distilled with a vacuum of 700 mmHg to remove water followed by filtration to separate the solid and liquid fractions. The liquid fraction is reacted with diethylene glycol to synthesize complex polyol ester base oil for lubricant. The base oil so obtained has a kinematic viscosity of 113 cSt at 40°C, pour point of -33°C and viscosity index of 109.

利用环己烷氧化废水制备润滑油用多元醇酯复合基础油

在空气中的环己烷氧化产生环己酮和Ç在cyclopol双过程yclohexanol与含有有价值羧酸废水流一起。本文设计了利用废水制备复杂的多元醇酯基础油的方法。古吉拉特邦肥料和化学有限公司的环己烷氧化过程产生的废水流。将其在700mmHg的真空下真空蒸馏以除去水，然后过滤以分离固体和液体部分。使液体馏分与二甘醇反应以合成用于润滑剂的复合多元醇酯基础油。如此获得的基础油在40°C下的运动粘度为113 cSt，倾点为-33°C，粘度指数为109。
