[求助] 翻译实验操作

Sulfonation reactions were carried out in 1,2dichloroethane at 50°C  using acetyl sulfate as the sulfonating agent.n The calcium, sodium, and zinc salts were prepared by titrating the sulfonic acid derivatives with the appropriate metal acetate. Subsequently, the polymers were precipitated with methanol (boiling water for the acid derivative),washed with methanol, and vacuum dried。
请问各位大侠,(boiling water for the acid derivative),,指的是加入沸水洗涤呢,还是加入水,煮沸蒸馏出溶剂?
