求翻譯:The mixture was then cooled to 0 °C, and the excess sodium hydride was quenched with water (20 mL). The reaction mixture was then poured on ice, followed by addition of 2 M HCl (5 mL), and the products were extracted with ethyl acetate(2 × 100 mL).是什么意思?![]() ![]() The mixture was then cooled to 0 °C, and the excess sodium hydride was quenched with water (20 mL).

然后將混合物冷卻至0℃,多余的鈉氫與水(20毫升)淬火。反應混合物倒在冰上,另外2 M鹽酸(5毫升),并用乙酸乙酯提取(2 × 100毫升)的產品。

該混合物冷卻,然后是0°C,超出氫化鈉是水淬.(20ml)。 的反應混合物是冰上然后倒,其次是另外的2M HCl(5ml),和有關產品是與提取乙酸乙酯(2×100毫升)。
