砂芯漏斗
砂芯漏斗-
结果表明：裂解蒸馏速度、馏出油取样量、乙醇纯度、温度、冷洗剂加入量、抽滤过程、砂芯漏斗的孔径是影响测定结果的显著因素。
The research result indicated splitting distillation velocity of flow , distillation production sample weight , the purity of alcohol , temperature , solvent amount , temperature , funnel aperture are the outstanding effect on determination accurate .
