Kev npaj
Kev npaj ntawm tert-butyl magnesium chloride: Siv cov ntawv xuab zeb tshem tawm cov oxide zaj duab xis rau ntawm qhov chaw ntawm magnesium sawb thiab txiav rau hauv cov chips zoo. Nyhav 3.6g (0.15 mol) ntawm magnesium chips, ntxiv rau plaub-caj dab ntim nrog cov khoom siv tiv thaiv nitrogen, stirrer, reflux condenser thiab lub siab tsis tu ncua drip funnel (CaCl2 drying tube yog ntsia rau saum lub reflux condenser. raj), qhia nitrogen rau hauv cov tshuaj tiv thaiv lub raj mis li 10 min, tshem tawm cov cua hauv plaub-caj dab, tom qab ntawd kho cov nitrogen ntws. tus nqi, thiab tsis tu ncua qhia me me nitrogen rau hauv cov tshuaj tiv thaiv kab mob. 35 mL ntawm refined tetrahydrofuran yog ntxiv rau plaub-caj dab, tom qab ntawd 13.9g (0.15 mol) ntawm tert-butyl chloride yog hnyav, txog 3.5g ntawm tert-butyl chloride yog ntxiv rau plaub-caj dab ua ntej, thiab qhov seem. 10.4g ntawm tert-butyl chloride yog tov nrog 150 mL ntawm refined tetrahydrofuran thiab tom qab ntawd ntxiv rau qhov kev sib cais tsis tu ncua. Ntxiv ib qho me me ntawm iodine, kub me ntsis, ib qho me me ntawm npuas tsim, xim ntawm iodine rov qab, nws yog ib qho tsim nyog yuav tsum ua kom cov tshuaj tiv thaiv kub npau npau me ntsis tom qab pib cov tshuaj tiv thaiv, tom qab poob, do rau 3 ~ 4 h, kom txog thaum cov magnesium chips ploj tag, qhia txog kev daws teeb meem grey.
