Intangiriro
Ethyl 2-choro-3-keto-4, 4,4-trifluorobutyrate ni ifumbire mvaruganda hamwe na formula ya chimique C6H7ClF3O3. Ibikurikira nintangiriro yimiterere yabyo, imikoreshereze, imyiteguro namakuru yumutekano:
Kamere:
-Ibigaragara: Amazi y'umuhondo adafite ibara cyangwa yoroheje
-Gushonga: -60 ° C.
-Icyerekezo: 118-120 ° C.
-Ubucucike: 1.432 g / mL
-Gukemuka: Gushonga mumazi hamwe na solge nyinshi
Koresha:
- Ethyl 2-chroo-3-keto-4, 4,4-trifluorobutyrate ikoreshwa nka reagent ikomeye muri synthesis. Irashobora gukoreshwa muguhuza ibindi bintu, nkibiyobyabwenge, imiti yica udukoko, amarangi, nibindi.
-Bishobora kandi gukoreshwa nk'inyongera ku bicuruzwa bikomoka ku buhinzi birwanya antifouling, irangi na kole.
Uburyo bwo Gutegura:
Synthesis ya ethyl 2-chloro-3-keto-4,4,4-trifluorobutyrate mubusanzwe bikorwa nintambwe zikurikira:
1.2-chloro-4, 4,4-trifluoroacetic aside ifata hamwe na anhydride ya chloroacetike ikabyara 2-chloro-4, 4,4-trifluoroacetyl chloride.
2.2-chloro-4, 4,4-trifluoroacetyl chloride noneho ikorwa hamwe na Ethyl acetate kugirango itange umusaruro wanyuma Ethyl 2-chloro-3-keto-4, 4,4-trifluobutyrate.
Amakuru yumutekano:
-Ethyl 2-chloro-3-keto-4,4,4-trifluorobutyrate ni uruganda ruhindagurika rushobora gutera ingaruka zizwi cyangwa zishobora guteza ubuzima.
-Iyo ikoreshwa igomba kubahiriza inzira z'umutekano, nko kwambara ibirahure birinda na gants.
-Irinde guhura nuruhu n'amaso, irinde guhumeka umwuka wacyo, kandi ukomeze guhumeka neza.
-Iyo ubitse, witondere kwirinda umuriro n'ubushyuhe bwinshi, kandi wirinde umuriro n'ibikoresho byaka.
Nyamuneka menya ko kugirango ukoreshe kandi ukoreshe imiti, hagomba gukurikizwa uburyo bwo gukora neza, kandi urupapuro rwerekana amakuru yumutekano (MSDS) rugomba gusomwa neza no gukurikizwa.
