Chaw Tsim Khoom Zoo Tus Nqi FORMAMIDE CAS: 75-12-7
Cov ntawv thov ntawm FORMAMIDE
1. Formamide siv ua cov tshuaj ua kom mos thiab ua cov tshuaj yaj rau cov kua nplaum thiab ntawv tsiaj, hauv kev sib hloov cov acrylonitrile copolymers, hauv kev sib xyaw cov amines tsis muaj roj, ua cov tshuaj yaj hauv kev tsim tshuaj, ua cov tshuaj yaj rau kev ntxuav roj, thiab rau cov khoom yaj uas tau hais los saum toj no. Siv ua cov khoom nruab nrab los ua cov tshuaj imidazole, pyrimidine, 1,3,5-triazine, caffeine, theophylline, theobromine. Siv ua cov khoom siv raw rau cov xim pleev, cov tshuaj tsw qab, cov xim pleev, cov nplaum, cov khoom siv textile, cov neeg sawv cev kho ntawv, thiab lwm yam. Cov khoom siv raw rau kev tsim cov kua qaub formic thiab dimethylformamide, thiab lwm yam.
2. Siv ua raw khoom rau kev tsim cov imidazole, pyrimidine, 1,3,5-triazine, caffeine, cov kuab tshuaj rau kev sib hloov ntawm acrylonitrile copolymer, txheej tiv thaiv cov khoom yas, thiab lwm yam.
3. Formamide muaj zog ua haujlwm thiab muaj peev xwm yaj tau zoo heev, thiab siv tau ua cov khoom siv raw rau kev tsim cov organic, tus neeg sawv cev kho ntawv, tus neeg ua kom mos rau kev lag luam fiber, tus neeg ua kom mos rau cov kua nplaum tsiaj, thiab ua tus neeg sawv cev tshuaj ntsuam xyuas rau kev txiav txim siab ntawm cov amino acid hauv mov. Hauv kev tsim cov organic, nws feem ntau siv rau hauv tshuaj, thiab kuj muaj ntau yam kev siv hauv cov tshuaj tua kab, cov xim, cov xim, cov tshuaj tsw qab, thiab cov khoom pabcuam. Nws kuj yog ib qho organic solvent zoo heev, feem ntau siv rau hauv kev sib hloov ntawm acrylonitrile copolymer thiab ion exchange resin, nrog rau cov txheej tiv thaiv hluav taws xob lossis cov txheej conductive ntawm cov khoom yas. Tsis tas li ntawd, nws kuj siv rau kev sib cais chlorosilane, purifying roj thiab lwm yam. Formamide tuaj yeem dhau los ntawm ntau yam kev tshuaj tiv thaiv. Ntxiv rau cov tshuaj tiv thaiv phau ntawv uas muaj peb hydrogens, nws kuj tuaj yeem dhau los ntawm kev qhuav dej, de-CO, kev qhia txog cov pab pawg amino, kev qhia txog cov pab pawg acyl thiab cyclization. Piv txwv li looping. Diethyl malonate yog cyclized nrog formamide kom tau txais 4,6-dihydroxypyrimidine, ib qho nruab nrab ntawm vitamin B4. Kev sib hloov ntawm anthranilic acid thiab amide kom tau txais cov quinazolone-4 nruab nrab ntawm cov tshuaj antiarrhythmic regular roline. Kev sib hloov ntawm 3-amino-4-ethoxycarbonylpyrazole thiab formamide kom tau txais xanthine oxidase inhibitor allopurinol. Ethylenediaminetetraacetic acid thiab formamide raug sib hloov kom tau txais cov tshuaj tiv thaiv kab mob qog noj ntshav ethyleneimine. Kev sib hloov ntawm methylethyl methoxymalonate thiab formamide ua rau disodium 5-methoxy-4,6-dihydroxypyrimidine, ib qho nruab nrab ntawm sulfonamides.
4. Siv ua analytical reagent, solvent thiab softener, kuj siv rau hauv organic synthesis.
5. Siv rau hauv kev lag luam tshuaj thiab tshuaj tua kab.
