[交流] 帮忙翻译一段话

x分别与α-萘酚和β-萘酚发生威廉姆逊反应生成醚, 然后醚上的酯基在KOH碱性条件下水解, 两步反应“一锅法”完成, 使合成化合物3a, 3b 的产率分别由两步法的43.8%和63.9%提高到“一锅法”的85.1%和91.2%, 方法简便, 易处理.

x react with α-naphthol and β-naphthol to ether respectively by Williamson reaction, then ester on the ether hydrolysis in the condition of alkaline KOH . The "one pot" method complete the two-step reaction, and the yield of product compounds 3a, 3b were 85.1% and 91.2%, which is better than  the yield of 43.8% and 63.9% through  two-step method. In the whole, the one pot method is simple and easy to handle.

The ether is formed by the Williamson reaction of X with Alpha alpha-naphthol and Beta alpha-naphthol dividedly, then estergroup on the ethers will be hydrolyzed under the koh alkaline condition

修改后:x react with α-naphthol and β-naphthol to ether respectively by Williamson reaction, then ester on the ether hydrolysis in the condition of alkaline KOH . The "one pot" method complete the two-step reaction, and the yield of product compounds 3a, 3b were 85.1% and 91.2%, which is better than  the corresponding yield of 43.8% and 63.9% through  two-step method.
