阿司匹林（乙酰水杨酸）已应用百年，成为医药史上三大经典药物之一，至今它仍是世界上应用最广泛的解热、镇痛和抗炎药，也是作为比较和评价其他药物的标准制剂。乙酰水杨酸受热易分解，分解温度为128_~135℃。某学习小组在实验室以水杨酸（邻羟基苯甲酸）与醋酸酐[（CH₃CO）₂O]为主要原料合成该物质，设计的合成路线为：
一、制备K
s*5u
二、提纯
方案1
方案2
主要试剂和产品的物理常数

名    称	相对分子质量	熔点或沸点（0C）	水	醇	醚
水杨酸	138	158(熔点)	微溶	易溶	易溶
醋酸酐	102	139.4(沸点)	反应	可溶	易溶
乙酰水杨酸	180	135(熔点)	微溶	可溶	微溶

请根据以上信息回答下列问题：                   
（1）①合成阿斯匹林时，还会生成一些副产品，其中有一种是高分子，为了分离此物质，方案1中加入A物质为   ▲   溶液。
②本方案抽滤后进行洗涤，其具体操作是   ▲    。
（2）方案2为改进的提纯方法，称为重结晶提纯法。
①该方案中步骤1除了选用乙酸乙酯外，还可选择下列哪些
试剂   ▲   。
A. 乙醇      B. 蒸馏水      C. 乙醚   
②步骤2回流的装置如图所示，写出仪器a的名称   ▲   ，使用温度计的目的是   ▲   ，冷凝水的流向为    ▲   。

③方案2所得产品的有机杂质要比方案1少的原因是   ▲   。
（3）该学习小组在实验中原料用量：2.0g水杨酸、5.0ml醋酸酐（ρ＝1.08g·cm^-3），
最终称量产品m="2.2g" ，则乙酰水杨酸的产率为   ▲    。
