Mawu Oyamba
3,4-difluorotoluene ndi organic pawiri ndi mankhwala chilinganizo C7H6F2. Ndi madzi opanda mtundu okhala ndi fungo lapadera lonunkhira. Zotsatirazi ndikulongosola mwatsatanetsatane za chilengedwe, kagwiritsidwe ntchito, kukonzekera ndi chitetezo cha 3,4-difluorotoluene:
Chilengedwe:
-Maonekedwe: madzi opanda mtundu
-Kukoma: Fungo lonunkhira lapadera
-Kutentha: 96-97 ° C
-Kuchulukana: 1.145g/cm³
-Kusungunuka: Kusungunuka m'madzi, kusungunuka mu zosungunulira za organic
Gwiritsani ntchito:
-3,4-difluorotoluene angagwiritsidwe ntchito ngati yofunika wapakatikati mu kaphatikizidwe organic.
-Itha kugwiritsidwa ntchito popanga mankhwala, utoto, mankhwala ophera tizilombo ndi mankhwala ena.
-Itha kugwiritsidwanso ntchito ngati zida zamagetsi zamagetsi.
Njira:
-3,4-difluorotoluene ili ndi njira zambiri zokonzekera, zomwe zimapezeka kwambiri ndi hydrogenation kuchepetsa zomwe p-nitrotoluene. Masitepe enieni ndi:
1. Choyamba, P-nitrotoluene imakhudzidwa ndi chitsulo chowonjezera cha diammonium sulfate kuti ipeze p-nitrotoluene iron diammonium mchere.
2. Hydrogen imawonjezeredwa, ndipo mchere wa p-nitrotoluene iron diammonium umakhudzidwa ndi kuchepetsa kuchepa pamaso pa chitsulo chothandizira.
3. Pomaliza, 3,4-difluorotoluene idayeretsedwa ndi distillation.
Zambiri Zachitetezo:
-3,4-difluorotoluene nthawi zambiri imawonedwa ngati yotetezeka ngati ikugwiritsidwa ntchito bwino. Komabe, m'pofunikabe kutsatira njira zoyenera zotetezera.
-Ndi madzi oyaka ndipo amayenera kupewa kukhudzana ndi moto komanso kutentha kwambiri.
-Magolovesi odzitetezera oyenerera, magalasi ndi zovala zodzitchinjiriza zimalimbikitsidwa kuti zigwiritsidwe ntchito ndi kunyamula.
-Khala kutali ndi chakudya, madzi komanso ana.
-Pakachitika mwangozi kapena kumeza mwangozi, funsani thandizo lachipatala mwamsanga ndikuwonetsa chizindikiro cha mankhwala kapena chidebecho kwa wothandizira zaumoyo.
