Daim ntawv thov

Tetrabutylurea (TBU)yog qhov sib xyaw ua ke feem ntau siv los ua cov kuab tshuaj thiab reagent nyob rau ntau yam tshuaj lom neeg. Cov ncauj lus kom ntxaws ntxiv, thov saib raws li:

1. Kuab zog hauv Synth System:1,1,3,3-tetrabutylureAce feem ntau siv los ua cov kuab tshuaj rau cov organic, tshwj xeeb tshaj yog nyob rau hauv cov synthesis ntawm ntau cov organic sib xyaw. Nws lub peev xwm los yaj ntau ntawm cov tshuaj polar thiab tsis muaj-polar ua rau nws muaj txiaj ntsig zoo hauv kev kuaj sim chaw.

2. Extraction thiab Cais:Tetra-N-Butylurea tuaj yeem siv rau hauv cov kua ua kua ua kua kom sib cais ua kom sib txawv raws li lawv solubility. Nws yog qhov tshwj xeeb hauv kev faib qee cov hlau ions thiab cov organic sib txuas los ntawm kev sib xyaw.

3. Reagents hauv tshuaj lom neeg cov tshuaj tiv thaiv:N, n, n, n

4. Cov cab kuj catalyst:Nyob rau hauv qee cov txheej txheem catalytic, TBU tuaj yeem siv ua catalyst cov cab kuj nruab nrab los txhim kho nws solubility thiab ua rau muaj kev sib xyaw ua ke.

Yuav ua li cas khaws cia tetrabutylurea?

Tetrabutylurea (TBU) yuav tsum khaws cia kom zoo los tswj nws cov kev ruaj khov thiab tiv thaiv ib qho kev phom sij. Nov yog qee cov lus qhia rau khaws cia TetrabutylureCurea:

1. Thawv:Khw muag khoom Tetrabutyl urea nyob rau hauv ib lub taub ntim kaw kom tiv thaiv kev ua paug thiab evaporation. Lub thawv yuav tsum tau ua cov ntaub ntawv uas tau tshaj tawm cov kuab tshuaj muaj zog, xws li iav lossis qee qhov plastics.

2. Kub:Khaws lub TBU hauv qhov chaw txias, qhuav qhov chaw kom deb ntawm kev tshav ntuj ncaj qha thiab cov khoom kub. Qhov tseeb, nws yuav tsum tau muab cia rau hauv chav tsev kub, tab sis tej yam kev cia tshwj xeeb yuav vam khom rau cov chaw tsim khoom pom zoo.

3. Qhov cua:Ua kom muaj cov chaw ntim khoom tau zoo kom txo qis cov neeg tsim cov hlab ntsha uas tuaj yeem tso tawm.

4. Cais los ntawm cov ntaub ntawv tsis sib xws:Khw muag khoom Tetrabutyl urea deb ntawm cov muaj zog oxidants, acids thiab lwm cov ntaub ntawv tsis sib xws los tiv thaiv cov kev phom sij.

5. Sau npe:Daim ntawv sau kom meej meej nrog cov npe siv tshuaj, kev xav, cov ntaub ntawv kev phom sij, thiab hnub tau txais. Qhov no pab xyuas cov tshuaj thiab ua kom muaj kev nyab xeeb tuav.
