Therefore, it is possible to use the cheap solvents (mixture of methanol and water) instead of the expensive hexane and acetone when the Accelerated Solvent Extraction method is employed.
这表明采用加速溶剂提取技术，可用价格较低的甲醇取代昂贵的正己烷和丙酮。
The results showed that it was a simple method with good reproducibility and high recovery rate in determining gossypol content in methanol phase from two-phase solvent extraction.
结果表明，该方法具有简便、重复性好、回收率高等优点，可用于双液相浸取棉仁的甲醇相中棉酚含量的测定。
METHOD Under the same conditions of microwave power and extraction time, methanol, alcohol, toluene, acetone and hexamethylene were used as the extractant to carry out intermittent extraction.
方法在微波功率和萃取时间一定的条件下，分别选用有机溶剂甲醇、乙醇、甲苯、丙酮及环己烷为提取剂，进行间歇性提取。
