Daim ntawv thov
1. Ua Tetrabutylurea ua ib qho kev ua haujlwm siab -kev ua tau zoo polar aprotic hnyav hauv cov organic synthesis, dissolving ntau cov organic / inorganic tebchaw rau kev siv tshuaj thiab tshuaj tua kab mob zoo.
2. Ua haujlwm NNNN TETRABUTYLUREA CAS 4559-86-8 ua cov hlau rho tawm hauv hydrometallurgy, sib cais thiab ua kom muaj txiaj ntsig zoo ntawm cov hlau ions hauv cov dej khib nyiab thiab cov ore leaching daws.
3. Ua haujlwm TBU raws li cov khoom siv polymer ntxiv thiab cov yas yas, txhim kho cov solubility thiab kev ua haujlwm ntawm cov resin, roj hmab thiab txheej formulations nrog zoo compatibility.
Cia thiab ceev faj
Khaws Tetrabutylurea (CAS 4559-86-8, tsis muaj xim pob tshab kua, faint amine tsw, flash point ≈167 degree, combustible) ntawm 10-25℃hauv kaw HDPE / amber iav ntim rau hauv qhov chaw txias, qhuav, zoo-ventilated. Cais tawm ntawm cov oxidants muaj zog, muaj zog acids thiab qhib nplaim taws kom tsis txhob decomposition thiab oxidation. Hnav hnab looj tes nitrile, looj tsom iav dub thiab daim npog ntsej muag; zam kev tiv thaiv ntawm daim tawv nqaij / qhov muag, vapor inhalation thiab noj kom tsis txhob mob me me mucosal. Reseal nruj nreem tom qab siv; pov tseg cov pov tseg ib lub zos urea derivative & nplua tshuaj ib puag ncig cov cai.
Dab tsi yog qhov txiaj ntsig ntawm kev noj Tetrabutylurea?
Tetrabutylurea yog cov kuab tshuaj muaj zog, extractant thiab polymer additive, tsis yog rau ncaj qha ncaj qha - tsim tib neeg kev sib cuag lossis kev noj; undiluted sib cuag tej zaum yuav ua rau daim tawv nqaij khaus, thiab kev tsis haum tshuaj yuav ua rau gastrointestinal tsis xis nyob thiab xeev siab. Hauv cov ntawv thov kev tswj hwm, NNNN TETRABUTYLUREA CAS 4559-86-8 nta zoo heev solubility thiab tshuaj stability, muaj tsawg volatility thiab zoo thermal kuj, thiab exhibits zoo extraction kev kawm rau precious hlau nrog siab selectivity.
