Intangiriro
3,4-difluorotoluene ni ifumbire mvaruganda hamwe na formula ya chimique C7H6F2. Nibintu bitagira ibara bifite impumuro idasanzwe. Ibikurikira nubusobanuro burambuye kumiterere, imikoreshereze, gutegura, amakuru yumutekano ya 3,4-difluorotoluene:
Kamere:
-Ibigaragara: amazi adafite ibara
-Kuryohe: Impumuro idasanzwe
-Ibintu bitetse: 96-97 ° C.
-Ubucucike: 1.145g / cm³
-Gukemuka: Kudashonga mumazi, gushonga mumashanyarazi
Koresha:
-3,4-difluorotoluene irashobora gukoreshwa nkigihe kinini cyingenzi muri synthesis.
-Bishobora gukoreshwa muguhuza ibiyobyabwenge, amarangi, imiti yica udukoko nindi miti.
-Bishobora kandi gukoreshwa nkibikoresho fatizo kubikoresho bya elegitoroniki.
Uburyo:
-3,4-difluorotoluene ifite uburyo bwinshi bwo gutegura, ibisanzwe biboneka kubwo kugabanya hydrogenation reaction ya p-nitrotoluene. Intambwe zihariye ni:
1. Ubwa mbere, P-nitrotoluene ikora hamwe na sulfate ya diammonium irenze urugero kugirango ibone umunyu wa p-nitrotoluene umunyu wa diammonium.
2. Hydrogene yongewemo, kandi p-nitrotoluene icyuma cya diammonium umunyu bigira ingaruka zo kugabanuka imbere ya catalizator.
3. Hanyuma, 3,4-difluorotoluene yahanaguwe no kuyungurura.
Amakuru yumutekano:
-3,4-difluorotoluene muri rusange ifatwa nkaho ifite umutekano mugihe gisanzwe cyo gukoresha. Ariko, biracyakenewe kubahiriza inzira zumutekano zijyanye.
-Ni amazi yaka kandi agomba kwirinda guhura numuriro nubushyuhe bwinshi.
-Ibikoresho bikwiye byo kurinda, amadarubindi n'imyenda ikingira birasabwa gukoreshwa no kubikora.
-Komeza kure ibiryo, amazi hamwe nabana.
-Mu gihe habaye impanuka cyangwa kumira impanuka, shakisha ubufasha bwihuse hanyuma werekane ikirango cyibicuruzwa cyangwa kontineri kubashinzwe ubuzima.
