Embodiment Construction
[0006] Add 200g of sclareolactone block solid mixture to the feeder of molecular distillation device (feeder volume 250ml, evaporation area 4.8 square decimeters, wiper speed 50~1000rpm), containing 90.5% of sclareolide %. Turn on the raw material preheating device, raise the temperature to 97°C, dissolve the solid and maintain a constant temperature. Turn on the cooling device, keep the cooling temperature at 35°C, add liquid nitrogen into the cold trap, turn on the rotary vane vacuum pump to make the operating pressure of the system reach 1.5Pa, turn on the precision constant temperature tank for evaporating materials to heat the heat transfer oil, so that the temperature Stabilize at the desired evaporation temperature of 99°C, then start the feed valve, the feed rate is 100g / h, and the rotating speed of the wiper is 138rpm. After the distillation process ends, 18.5g of distillate and 181.5g of heavy fraction are obtained; The heavy distillate obtained from the first disti...
