This was from a paper on the extraction of lanosterol.
First, the saponification of the crude lanolin alcohol was performed, and then the unsaponifiable products were removed by molecular distillation.
When the fixed system pressure, preheating temperature and condensing temperature were 0.1 Pa, 80 _C, 70 _C respectively, the effects of evaporating
temperature, feed rate and rotor rate on the content and recovery of cholesterol were examined and the best response conditions were obtained by RSM.
The evaporating temperature, feed rate and rotor rate were 183.64 _C, 3.58 ml/min and 277 rpm, respectively. Under these conditions, the content of
cholesterol obtained was 17.5%.
I'm wondering what device they used for this. A kugelrohr?
