Taw qhia
4-isobutylacetophenone, tseem hu ua 4-isobutylphenylacetone, yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: 4-Isobutylacetophenone yog cov kua tsis muaj xim, los yog kua daj rau xim av.
- Solubility: Nws muaj solubility zoo hauv cov kuab tshuaj organic.
- Cia ruaj khov: Nws yuav tsum muab cia rau hauv qhov chaw txias, qhuav, zoo-ventilated qhov chaw deb ntawm lub hnub ncaj qha.
Siv:
Txoj kev:
- Kev npaj ntawm 4-isobutylacetophenone feem ntau ua tiav los ntawm acid-catalyzed alkylation. Muaj ntau ntau txoj kev npaj tshwj xeeb, ib qho ntawm cov tshuaj tiv thaiv acetophenone thiab isobutanol nyob rau hauv acidic tej yam kev mob kom tau txais lub hom phiaj cov khoom.
Cov ntaub ntawv kev nyab xeeb:
- Kev saib xyuas yuav tsum tau saib xyuas kom tsis txhob muaj 4-isobutylacetophenone los ntawm kev sib cuag nrog lub qhov muag, tawv nqaij, thiab ua pa.
- Hnav hnab looj tes, tsom iav, thiab daim npog ntsej muag thaum tuav, khaws cia, thiab tuav. Xyuas kom lub chav tsev yog qhov zoo ventilated.
- Yog tias muaj kev sib cuag nrog cov khoom sib tsoo, tam sim ntawd yaug nrog dej kom ntau li 15 feeb thiab nrhiav kev kho mob.
- Cov ntaub ntawv kev nyab xeeb tshwj xeeb yuav tsum tau txiav txim siab raws li qhov xwm txheej tiag tiag thiab cov ntawv qhia kev nyab xeeb uas cuam tshuam los xyuas kom cov neeg ua haujlwm muaj kev paub txog kev paub thiab kev paub txog kev ua haujlwm ntawm kev sim tshuaj.
