Chaw tsim tshuaj paus zoo nqe formamide CAS: 75-12-7

1. Formamide yog siv los ua cov khoom muag thiab cov kuab tshuaj pleev rau cov tsiaj txhu thiab cov kuab tshuaj pleev tau, raws li cov kuab tshuaj uas tsis muaj kuab, raws li cov kuab tshuaj kom huv, thiab rau cov saum toj no cov khoom tsis sib xws. Siv los ua nruab nrab rau cov hluavtaws imidazole, pyrimidine, pyrimidine, 1,3,3,5-triazine, caffeine, theophylline, mobromline, mobromline, mobromline, mobromine. Siv los ua cov ntaub ntawv raw rau dyes, cov tshuaj tsw qab, cov tshuaj nplaum, cov ntaub ntawv tshuaj xyuas cov ntaub ntawv, thiab lwm yam khoom siv rau cov formic acid thiab dimethylformamide, thiab lwm yam.

2. Siv los ua cov khoom siv raw rau synthesizing imidazole, 1,3,5-triazine, kuab tshuaj rau spining ntawm acrylonitrile copolymer, cov tshuaj tivthaiv cov tshuaj tiv thaiv cov khoom yas, thiab lwm yam.

3. Formamide tau muaj peev xwm ntau yam thiab siv tau tshwj xeeb, thiab siv tau cov khoom siv tshuaj khib nyiab, thiab ua ib qho kev ntsuas cov khoom siv rau kev txiav txim siab ntawm cov khoom noj Cov. Hauv cov synthic synthesis, feem ntau yog siv nyob rau hauv cov tshuaj, thiab kuj tseem muaj ntau yam siv tshuaj tua kab, dyes, pigments, tshuaj tsw qab, thiab cov tshuaj tsw qab. Nws kuj yog ib qho zoo heev organic hnyav, feem ntau yog siv nyob rau hauv spinlonitrile copolymer thiab ion txauv txauv cov khoom siv lossis cov khoom siv yas. Ib qho ntxiv, nws tseem siv rau kev cais chlorosilane, purifying roj thiab lwm yam. Formamide tuaj yeem yauv tau ntau yam kev tawm tsam. Ntxiv rau cov tshuaj lom neeg tshuaj lom neeg muaj feem nrog peb lub hydrogens, nws tseem tuaj yeem dhau lub cev qhuav dej, de-co, pawg ntawm cov acyl pawg thiab huab cua. Muab looding ua piv txwv. Diethyl malonate is cyclized with formamide to obtain 4,6-dihydroxypyrimidine, an intermediate of vitamin B4. Cyclization ntawm anthranilic acid thiab txoj hauv kev kom tau txais nruab nrab quinazolone-4 ntawm Antiarrhytherththmic Roline. Cyclization ntawm 3-amino-4-Ethosycarbonylprozole thiab formamide kom tau xanthine oxidase allegurinol. EthylenedIninetetraimetic acid thiab formamide yog cyclized kom tau txais cov anticancer cov ethylenine. The cyclization of methylethyl methoxymalonate and formamide yields disodium 5-methoxy-4,6-dihydroxypyrimidine, an intermediate of sulfonamides.

4. Siv los ua kev ntsuas cov tshuaj tiv thaiv, hnyav thiab muag thiab muag, kuj siv hauv cov synthic synthesis.

5. Siv tshuaj thiab tshuaj tua kab.
