Ntu 5: Yuav Ua Li Cas Kom Tau Nws
1. Muab tau los ntawm qhov nruab nrab ntawm formic acid thiab ammonia. Txias cov formic acid thiab dej, ua rau cov pa roj ammonia ua kom tus nqi pH yog 7-7.5, txo qhov kub thiab txias mus rau -5âº, thiab spin-filter kom tau txais nws.
2. Hauv 90% formic acid tov, dhau ammonia roj.
Tom qab ib tug txaus npaum li cas ntawm ammonia gas yog qhia, qhov kub thiab txias tso tawm yuav txhawb lub nag los ntawm nws. Cov crystals tau lim, recrystallized los ntawm ethanol kiag li, thiab qhuav nyob rau hauv lub tshuab nqus tsev desiccator nruab nrog 99% sulfuric acid.
3. 100 qhov chaw ntawm methyl formate, 100 qhov chaw ntawm dej, 0.1 feem ntawm formic acid, kho cov pH rau 2.5, cua sov rau 70 ° C nrog nplawm, ntxiv 20 feem ntawm ammonia dej, khaws pH ntawm 2 ~ 3, tom qab hais txog. 1h, 70% formic acid Cov methyl ester tau hydrolyzed. Internal steaming yog nqa tawm. Thaum qhov kub ntawm lub taub hau distillation yog 10 ° C, unreacted methyl formate thiab methanol distilled tawm, tawm hauv acidic tov ntawm nws nyob rau hauv lub evaporator. Neutralize nrog ammonia thiab rov evaporate kom tau nws nrog 98% cov ntsiab lus
