daim ntawv thov
Formamide muaj active reactivity thiab tshwj xeeb dissolution muaj peev xwm, yuav siv tau raws li organic synthesis raw khoom, daim ntawv kho tus neeg saib xyuas, fiber kev lag luam softener, tsiaj kua nplaum softener, thiab kuj siv raws li ib tug analytical reagent los txiav txim cov amino acid cov ntsiab lus nyob rau hauv mov. Nyob rau hauv cov organic synthesis, kev siv tshuaj feem ntau, thiab muaj ntau yam siv tshuaj tua kab, dyes, pigments, spices, auxiliaries. Nws kuj yog ib qho zoo heev organic hnyav, feem ntau yog siv nyob rau hauv spinning thiab ion pauv resins ntawm acrylonitrile copolymer, nrog rau anti-static txheej los yog conductive txheej ntawm cov khoom yas. Tsis tas li ntawd, nws kuj yog siv los cais cov chlorosilane, ntxuav cov roj thiab lwm yam. Formamide tuaj yeem ua rau muaj ntau yam kev tshwm sim. Ntxiv nrog rau cov tshuaj tiv thaiv uas muaj peb hydrogens, nws tseem tuaj yeem ua rau lub cev qhuav dej, deCO, kev qhia txog cov amino pawg, kev taw qhia ntawm acyl pawg thiab cyclization. Ua piv txwv txog kev sib koom ua ke. Diethyl malonate yog cyclically ua ke nrog formamide kom tau 4, 6-dihydroxypyrimidine, ib nrab ntawm cov vitamin B4. Anthranilic acid tau ua ke nrog amide kom tau txais antiarrhythmic intermediate quinazolone-4. Cov xanthine oxidase inhibitor allopurinol tau txais los ntawm cyclic synthesis ntawm 3-amino-4-ethoxycarbonyl pyrazole nrog formamide. Ethylenediamine tetraacetic acid tau ua ke nrog formamide kom tau txais cov tshuaj tiv thaiv kab mob ethylide. Methyl ethyl methoxymalonate yog cyclically ua ke nrog formamide kom tau qhov nruab nrab ntawm sulfonamides, 5-methoxy-4, 6-dihydroxypyrimidine disodium.
