daim ntawv thov

Formamide muaj cov tshuaj tiv thaiv thiab muaj peev xwm yaj tau zoo heev, siv tau ua cov khoom siv raw organic synthesis, tus neeg sawv cev kho ntawv, tshuaj ua kom mos rau kev lag luam fiber, tshuaj ua kom cov kua nplaum tsiaj mos, thiab kuj siv tau ua cov tshuaj reagent los txiav txim siab cov amino acid hauv mov. Hauv kev tsim cov organic, kev siv tshuaj feem ntau yog, thiab muaj ntau yam siv rau hauv cov tshuaj tua kab, cov xim, cov xim, cov txuj lom, thiab cov khoom pabcuam. Nws kuj yog cov organic solvent zoo heev, feem ntau siv rau hauv kev sib hloov thiab ion pauv resins ntawm acrylonitrile copolymers, nrog rau kev tiv thaiv static txheej lossis conductive txheej ntawm cov khoom yas. Tsis tas li ntawd, nws kuj siv los cais chlorosilane, ntxuav roj thiab lwm yam. Formamide tuaj yeem dhau ntau yam kev tshuaj tiv thaiv. Ntxiv nrog rau kev tshuaj tiv thaiv uas muaj peb hydrogens, nws kuj tuaj yeem dhau los ntawm kev qhuav dej, deCO3, kev qhia txog pawg amino, kev qhia txog pawg acyl thiab cyclization. Piv txwv li, siv lub voj voog sib koom ua ke. Diethyl malonate yog cyclically sib xyaw nrog formamide kom tau txais 4,6-dihydroxypyrimidine, ib qho nruab nrab ntawm vitamin B4. Cov kua qaub anthranilic tau muab sib xyaw nrog amide kom tau txais cov tshuaj quinazolone-4 uas tiv thaiv kev ntxhov siab. Cov tshuaj xanthine oxidase inhibitor allopurinol tau txais los ntawm kev sib xyaw ua ke ntawm 3-amino-4-ethoxycarbonyl pyrazole nrog formamide. Ethylenediamine tetraacetic acid tau sib xyaw nrog formamide kom tau txais cov tshuaj tiv thaiv kab mob qog noj ntshav ethylimide. Methyl ethyl methoxymalonate tau sib xyaw ua ke nrog formamide kom tau txais cov tshuaj sulfonamides, 5-methoxy-4, 6-dihydroxypyrimidine disodium.
