The hydroxyl value analysis of acrylate-styrene copolymcr solution by usillg acetylchloride as an acetylating agent is discussed.
结合对体系所含双氧水浓度的,乙酰氯法量了合双氧水的丙烯酸酯-苯乙烯共聚物溶液体系的聚合物的羟。

结合对体系所含双氧水浓度的,乙酰氯法量了合双氧水的丙烯酸酯-苯乙烯共聚物溶液体系的聚合物的羟。
Because of all these disvantages acetylchloride is used to react with absolute ethyl alcohol and synthesize ethyl acetate.
鉴于传统方法存在上缺点,采用乙酰氯代替乙酸作为原料,使用任何催化,热,常温反应来合成乙酸乙酯。
