Formamide, ib qho organic compound nrog cov mis molecular CH3NO, yog cov xim tsis muaj xim, pob tshab kua nrog me ntsis ammonia tsis hnov tsw, uas yog cov khoom siv raw rau synthesizing tshuaj, txuj lom, dyes, thiab lwm yam. Nws kuj yog siv los ua ib qho hnyav rau extraction ntawm hluavtaws fibers, plastics processing, thiab zus tau tej cov lignocellulosic inks.
Formamide Solubility
- Solubility: insoluble nyob rau hauv ether thiab chlorinated kuab tshuaj, me ntsis soluble nyob rau hauv benzene, miscible nrog dej, methanol, ethanol, acetic acid, acetone, dioxane, ethylene glycol, phenol, thiab qis - qib esters. Nws tuaj yeem yaj casein, tab sis tsis yog albumin.
- Formamide kuj solubilizes casein, qabzib, zein, gelatin, tsiaj kua nplaum, resins, starch, lignin, acetate fibers, nylon, thiab tej yam inorganic ntsev, chlorides ntawm tooj liab, lead, zinc, tin, cobalt, hlau, txhuas, thiab npib tsib xee, sulfates, thiab nitrates.
Formamide Chemical Properties
Lub hydrolysis ntawm formamide qeeb ntawm chav tsev kub, thiab tuaj yeem ua kom nrawm dua los ntawm kev nce qhov kub los yog ntxiv cov kua qaub lossis cov hauv paus. Nyob rau hauv lub xub ntiag ntawm ib tug catalyst, cua kub kom qis dua 35℃yuav decompose hydrogen cyanide. Formamide muaj ob pawg ua haujlwm nquag, piv txwv li, pawg carbonyl thiab amide pawg, uas yooj yim rau kev ua tshuaj lom neeg thiab tsim ntau cov nitrogen- muaj cov tshuaj heterocyclic. Formamide tuaj yeem cuam tshuam nrog inorganic acids los tsim formic acid thiab ammonium ntsev. Nyob rau hauv lub xub ntiag ntawm ib tug catalyst, nws muaj peev xwm hnov nrog organic halides los yog cawv los tsim formic acid esters. Nws tuaj yeem cuam tshuam nrog -diketones, -iminones, aliphatic couplings, aromatic couplings, thiab heterocyclic couplings. Nws tuaj yeem ua ke nrog cobalt ntsev, tooj liab ntsev, thiab nickel ntsev los tsim cov complexes. Thaum formamide ntsib tus neeg sawv cev lub cev muaj zog xws li phosphorus pentoxide, nws tuaj yeem tsim hydrogen cyanide. Nws tuaj yeem hnov mob nrog phosphorus pentasulfide los ua sulfur formamide. Formamide tuaj yeem ua rau tooj liab, tooj dag, txhuas, thiab roj hmab, yog li nws yuav tsum tau them sai sai rau thaum khaws cia thiab thauj.
Kev siv Formamide
- Formamidemuaj cus ciav reactivity thiab tshwj xeeb solubility, yuav siv tau raws li ib tug raw khoom rau organic synthesis, ib daim ntawv kho tus neeg sawv cev, ib tug softener rau lub fiber kev lag luam, ib tug softener rau tsiaj kua nplaum, 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, feem ntau ntawm kev siv tshuaj, tshuaj tua kab, dyes, pigments, spices, thiab additives kuj muaj ntau yam kev siv.
- Nws yog siv los ua ib qho nruab nrab los ua ke imidazole, pyrimidine, 1,3,5-triazine, caffeine, theophylline, thiab theobromine. Siv los ua raw khoom rau dyestuffs, fragrances, pigments, adhesives, textile auxiliaries, thiab ntawv kho mob. Raw khoom rau zus tau tej cov formic acid thiab dimethylformamide.
- Formamide kuj yog ib qho zoo heev organic hnyav, feem ntau yog siv nyob rau hauv spinning ntawm acrylonitrile copolymer thiab ion pauv resins, nrog rau anti- txheej zoo li qub los yog conductive txheej ntawm cov khoom yas.
Vim li cas thiaj xaiv Gneebio?
Gneebio, nrog ntau xyoo dhau los ntawm kev tshawb fawb, kev tsim khoom, thiab kev lag luam ntawm cov tshuaj organic, yog ib qho ntawm cov khoom xa tawm ntawm cov khoom siv tshuaj hauv Henan, Suav. Tau ntau xyoo, peb tau cog lus rau kev lag luam tshuaj lom neeg ntawm cov khoom nruab nrab, cov khoom siv yas, cov tshuaj kho dej thiab cov tshuaj fungicides, thiab cov tshuaj niaj hnub.
