ethyl acetate

ethyl acetate的音标为['i:θi?u, e?t?e?t] ，中文翻译为“乙酸乙酯”。其词源是拉丁语词根，其中“ethyl”代表“乙基”，而“acetate”代表“醋酸盐或酯”。因此，这个词的意思是乙基醋酸盐或乙酯。 #

对于ethyl acetate的速记技巧，可以尝试以下变化形式：

#

1. 联想记忆：将ethyl与“易脂”谐音化联想，将acetic酸化理解为“酸易”，那么ethyl acetate就可以理解为“易酸酯”，是一个比较容易记忆和储存的词汇。

#

2. 词根词缀记忆：ethyl是“乙基”的意思，acetic是“乙酸基”的意思，两者结合就是“乙酸基基乙酯”，即醋酸乙基基乙酯，是一种有机溶剂。 #

3. 图像化记忆：在脑海中构建一幅图像，比如想象一个装着醋的杯子，醋旁边放着一些蛋糕，而蛋糕是用乙基醋酸基酯制成的。这样的想象可以帮助将ethyl acetate与现实生活联系起来，从而更容易记忆。

4. 声音记忆：将ethyl acetate发音化为“易酸挨册”，通过有节奏和韵律的声音来帮助记忆。
