Intangiriro
ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE (ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE) ni urugimbu. Ibikurikira nubusobanuro bwimiterere yabyo, imikoreshereze, imyiteguro namakuru yumutekano:
Kamere:
-Ibigaragara: Mubisanzwe ni ibara ritagira ibara cyangwa ibara ry'umuhondo.
-Gukemuka: Irashobora gushonga mumashanyarazi kama, nka Ethanol, ether na dichloromethane.
-Gushonga hamwe no guteka: Ahantu ho gushonga ni -8 ° C, naho aho itetse ni 108-110 ° C.
Koresha:
-igaragaza muri Synthesis ya Organic Advanced: ETHYL 4,4, 4-trifluororo-2-butynoate irashobora gukoreshwa nka reagent ikomeye muri synthesis. Irashobora kugira uruhare muburyo butandukanye bwibinyabuzima, nka acylation, condensation na cycleisation reaction, ikoreshwa muguhuza ibinyabuzima bitandukanye.
-Ubutaka bwa chimie: Irashobora kandi gukoreshwa mubitekerezo bimwe na bimwe bya chimie ya polymer, nkibikoresho byuzuzanya bya polymrike.
Uburyo:
ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE irashobora gutegurwa nintambwe zikurikira:
1. Ubwa mbere, butynol (2-butynol) isubizwa hamwe na hydrogène hydrogène ya hydrogène kugirango itange fluoride ya butynyl.
2. Hanyuma, fluoride ya butynyl isubizwa hamwe na ETHYL chloroacetate kugirango itange ETHYL 4,4, 4-trifluororo-2-butynoate.
Amakuru yumutekano:
- ETHYL 4,4,4-TRIFLUORO-2-BUTYNOATE igomba kwirinda guhumeka ikirere igihe kirekire kuko yunvikana nubushuhe namazi.
-Bigomba kwirinda umuriro ufunguye hamwe nubushyuhe bwinshi mugihe cyo gukora no kubika, kuko birashya.
-Ibikorwa bikwiye byo gukingira bigomba gufatwa mugihe ukoresheje no kubikemura, harimo kwambara uturindantoki, masike hamwe nikirahure kirinda.
-Bigomba kubikwa ahantu hakonje, humye kandi gahumeka neza.
