Abstract
【選択図】図1
Description
高純度水(500mL、BDH;18mΩ)を、1リットルの三つ口の丸底フラスコに入れた。ガラスの撹拌棒を、中央の口を通して、550rpmの撹拌速度に設定されているオーバーヘッド撹拌器に取り付けた。フラスコの側面の口の1つに、温度計(0〜110℃の温度幅)を取り付けた。撹拌しながら、水温を45℃にまで上昇し、硝酸銀(90mg−99.9999%;Aldrich Chemicals)を、フラスコの第三の口から加えた。フラスコ内容物の温度を急速に98℃に上昇させ、10mLのクエン酸リチウム溶液(25mLのBDH高純度水中、227mg)を反応混合物に加えた。
