Intshayelelo
Ukwazisa imveliso yethu yamva nje i-4-Fluorobenzoylacetonitrile, ikhompawundi efunwa kakhulu kwishishini lamachiza kunye nelemichiza. Le khompawundi entsha isetyenziswe ngokubanzi ekudityanisweni kweekhompawundi ezahlukeneyo zendalo, iyenza ibe licandelo elibalulekileyo kuyilo nophuhliso lwamachiza.
I-formula yekhemikhali ye-4-Fluorobenzoylacetonitrile yi-C9H6FNO, kwaye inobunzima be-molecular 163.15 g / mol. Inombolo yayo ye-CAS yi-4640-67-9, kwaye iyikristale etyheli okanye i-orenji eqinile kunye nozinzo oluhle kakhulu kunye nobomi beshelufu.
Ukucoceka kwemveliso yethu yi-99%, okwenza ukuba ifaneleke kwizicelo ezahlukeneyo. Ineqondo lokubila lika 298-300°C, kwaye iqondo lokunyibilika layo lisuka ku 69°C ukuya kuma 72°C. Iyanyibilika kwizinyibilikisi eziqhelekileyo ze-organic ezifana ne-ethanol, i-ether, kunye ne-dichloromethane, eyenza kube lula ukuyiphatha kunye nokusetyenziswa.
Enye yeenzuzo ezibalulekileyo ze-4-Fluorobenzoylacetonitrile kukuguquguquka kwayo kwi-organic synthesis. Isebenza njengebhloko yokwakha kwi-synthesis yeentlobo ezahlukeneyo zezinto eziphilayo ezifana ne-4-Fluorobenzaldehyde, i-4-fluoro-2-hydroxymethylbenzoic acid, kunye ne-4-Fluorobenzoic acid. Oku kuguquguquka kwenza ukuba ibe sisithako esibalulekileyo kwishishini loxubo-mayeza, apho lisetyenziswa kuyilo nophuhliso lwamachiza.
Ngaphandle kwamachiza, i-4-Fluorobenzoylacetonitrile isetyenziselwa ukuveliswa kweekhemikhali ze-agrochemicals, iziqhumiso, kunye nedayi. Ikwasetyenziswa njenge-reagent yohlalutyo lwee-amino acids kunye neeprotheni kwishishini lemichiza.
Njengenkampani, sizama ukubonelela ngeemveliso ezikumgangatho ophezulu ezihlangabezana neemfuno zabathengi bethu. Imveliso yethu ye-4-Fluorobenzoylacetonitrile yenziwa phantsi kwemilinganiselo engqongqo yokulawula umgangatho ukuqinisekisa ukucoceka kwayo kunye nomgangatho. Siyazingca ngokukwazi kwethu ukubonelela abathengi bethu ngemveliso ehambelanayo kunye nethembekileyo.
Ukuqukumbela, i-4-Fluorobenzoylacetonitrile iyisithako esibalulekileyo kwishishini lamachiza kunye neekhemikhali, kunye nokusetyenziswa okuguquguqukayo kwi-organic synthesis. Ukucoceka kwayo okuphezulu kunye nokuzinza kwenza kube yinto ekhethiweyo yoyilo kunye nophuhliso lweziyobisi. Xhumana nathi namhlanje ngekhwalithi ephezulu ye-4-Fluorobenzoylacetonitrile ehlangabezana neemfuno zakho zemveliso.
