Taw qhia
AFBX yog cov xim tsis muaj xim crystalline. Nws melting point yog hais txog 260-261 degrees Celsius. Nws ruaj khov ntawm chav tsev kub thiab tuaj yeem yaj hauv cov kuab tshuaj tsis tu ncua.
Siv:
AFBX feem ntau yog siv los ua qhov nruab nrab rau tshuaj tua kab thiab tshuaj tua kab. Nws muaj cov tshuaj tua kab zoo thiab tshuaj tua kab mob thiab tuaj yeem siv tawm tsam ntau yam kab tsuag thiab nroj tsuag. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua tus tswj kev loj hlob ntawm cov nroj tsuag hauv kev ua liaj ua teb.
Txoj kev:
Lub synthesis ntawm AFBX tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm 2,2-difluoro -1,3-benzobisoxazole nrog ammonia. Cov tshuaj tiv thaiv feem ntau nqa tawm ntawm qhov kub thiab txias, thiab cov tshuaj tiv thaiv tuaj yeem tiv thaiv los ntawm nitrogen lossis lwm yam roj inert. Cov txheej txheem hluavtaws tshwj xeeb kuj muaj cov txheej txheem tshuaj lom neeg, suav nrog kev xaiv cov tshuaj tiv thaiv kab mob thiab cov catalysts.
Cov ntaub ntawv kev nyab xeeb:
AFBX kuj muaj kev nyab xeeb raws li qhov tseeb ntawm kev siv thiab khaws cia. Txawm li cas los xij, nws yog cov tshuaj lom neeg, yog li nws yuav tsum ua raws li qee cov txheej txheem kev nyab xeeb. Cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes, hnab looj tes thiab lub tsho tiv thaiv yuav tsum tau siv thaum tuav thiab kov AFBX. Tsis txhob kov ntawm daim tawv nqaij, qhov muag thiab ua pa. Yog tias muaj kev sib cuag, yaug nrog dej tam sim ntawd. Tib lub sijhawm, kev siv thiab pov tseg ntawm AFBX yuav tsum ua raws li cov cai hauv zos thiab cov lus qhia.
