| Txoj Kev Purification | Chav distil nws los ntawm cov kev daws teeb meem uas muaj txog 1.2 qhov sib npaug ntawm 20% H2SO4, kom txog rau thaum ca 10% ntawm lub hauv paus tau nqa mus nrog cov tsis yog cov impurities. Cov kua qaub yog tom qab ntawd ua alkaline, thiab lub hauv paus yog sib cais, qhuav dhau NaOH los yog BaO, thiab fractionally distilled. Lub distilled lutidine hloov mus rau nws cov urea complex los ntawm nplawm 100g nrog 40g ntawm urea nyob rau hauv 75mL ntawm H2O, txias rau 5o, lim ntawm lub twj tso kua mis, thiab ntxuav nrog 75mL ntawm H2O. Lub complex, yaj nyob rau hauv 300mL ntawm H2O, yog chav distilled kom txog thaum lub distillate muab tsis muaj turbidity nrog me ntsis khoom NaOH. Cov distillate yog tom qab ntawd kho nrog cov khoom ntau dhau NaOH, thiab txheej txheej sab saud raug tshem tawm: cov txheej txheem dej yog ces muab rho tawm nrog diethyl ether. Cov txheej sab saud thiab cov ether extract tau ua ke, qhuav (K2CO3), thiab distilled los ntawm ib kem luv. Qhov kawg purification yog los ntawm fractional crystallisation siv ib nrab khov. Cov picrate crystallises los ntawm EtOH nrog m 187-188o. [Kyte et al. J Chem Soc 4454 1960, Beilstein 20 H 243, 20 II 159, 20 III/IV 2765, 20/6 V 15.] |
