● Siv: TetrabutylureEA, tseem hu ua Tetra-N-ButylureAce lossis TBU, yog cov tshuaj sib xyaw nrog cov mis molecular (C4H9) 4Nkonh2. Nws zwm rau hauv chav kawm ntawm urea derivatives.Trhabutylurea yog cov kua tsis muaj xim xws li ethanol, ethyl acetate, thiab dichhloromethane. Nws muaj qhov tseem kub heev boiling point thiab qis vapor siab.Qhov compound nrhiav tau cov ntawv thov hauv ntau yam kev siv tshuaj organic, chaw muag tshuaj paus, thiab electrochemistry, thiab ultrasonicememistry. Nws tuaj yeem raug siv los ua cov kuab tshuaj, pawg neeg saib xyuas, thiab catalyst hauv cov tshuaj lom neeg. Tseem yog paub txog nws lub peev xwm los yaj ntau ntawm cov kav hlau hlau thiab hlau ua kom nco ntsoov tias TBU tuaj yeem yog tshuaj lom thiab yuav tsum tau ua kom haum. Thov ua raws li txhua qhov kev ceev faj kev nyab xeeb thiab cov txheej txheem thaum ua haujlwm nrog cov tshuaj no.
