求翻译：Cool the reactor below 30 degrees and release the reflux solvent including the fraction in the condenser return line when the reflux-sampling solution becomes without color, turbidity, layering and particulate matters. Keep the vacuum at -0.03MPa to -0.06MPa, first nitrogen purging the reactor for 10 minutes, and then 是什么意思？ 待解决
