Taw qhia
Fluoropropionone (tseem hu ua benzene 1-fluoroacetone) yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm fluoropropionone:
Zoo:
Cov tsos mob: Fluoropropion yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw muaj zog.
Ceev: Qhov ceev ntawm fluoropropion yog hais txog 1.09 g / cm³.
Solubility: Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol, ether thiab acetone, tab sis insoluble hauv dej.
Reactivity: Nws tuaj yeem hnov mob nrog tus neeg sawv cev txo qis los tsim cov cawv sib txuas. Fluoropropiophenone tuaj yeem raug cuam tshuam los ntawm cov tshuaj oxidizing.
Siv:
Fluoropropiophenone muaj qee yam kev siv, feem ntau suav nrog:
Raws li cov organic synthesis reagent: Fluoropropion tuaj yeem siv los ua ligand lossis koom nrog ntau cov organic tshuaj, xws li fluorination thiab acylation.
Raws li surfactant: vim nws cov qauv tshwj xeeb thiab cov khoom siv, nws muaj peev xwm siv tau hauv kev ntub dej, decontamination thiab emulsification.
Txoj kev:
Fluoropylacetone tuaj yeem npaj tau los ntawm cov tshuaj tiv thaiv ntawm fluorinated acetone thiab benzene, feem ntau nyob rau hauv cov xwm txheej ntawm kev ntxiv fluorinating tus neeg sawv cev catalyst xws li boron trifluoride (BF3) los yog txhuas fluoride (AlF3) nyob rau hauv ib qho chaw inert.
Cov ntaub ntawv kev nyab xeeb:
Fluoropropion yog khaus thiab yuav ua rau khaus thiab kub hnyiab ntawm daim tawv nqaij thiab qhov muag. Kev ceev faj tsim nyog, xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv, yuav tsum tau ua thaum sib cuag.
Nws yog combustible thiab yuav tsum tau khaws cia kom deb ntawm qhib nplaim taws thiab kub qhov chaw. Thaum tuav thiab khaws cia, kev tiv thaiv hluav taws yuav tsum tau ua.
Thaum siv hauv chav kuaj thiab kev lag luam, cov txheej txheem kev khiav hauj lwm yuav tsum tau ua raws li kom tsis txhob muaj kev cuam tshuam tsis zoo nrog lwm yam khoom siv phom sij.
Fluoropionone yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav thiab zoo-ventilated, deb ntawm hluav taws thiab oxidants.
