Sethula i-2-Fluoro-3-iodopyridine (CAS# 113975-22-7), isakhi esinqunyiwe esenza amagagasi emkhakheni we-organic chemistry kanye nocwaningo lwezemithi. Le khemikhali emisha ibonakala ngesakhiwo sayo samangqamuzana esiyingqayizivele, esihlanganisa kokubili okufakwe esikhundleni se-fluorine ne-iodine eringini ye-pyridine, okuyenza ibe yisakhiwo esibalulekile sokusetshenziswa okuhlukahlukene.
I-2-Fluoro-3-iodopyridine yaziwa ngokuhlukahluka kwayo kumakhemikhali okwenziwa, ikakhulukazi ekuthuthukisweni kwemithi emisha kanye namakhemikhali ezolimo. Ukuba khona kwe-athomu ye-fluorine kuthuthukisa ukuzinza kwe-compound kanye ne-lipophilicity, kuyilapho i-athomu ye-iodine inikeza amathuba okusebenza okwengeziwe ngokusabela okuhlanganayo. Le nhlanganisela yezakhiwo ivumela abacwaningi ukuthi bahlole izindlela ezintsha ekutholakaleni nasekuthuthukisweni kwezidakamizwa, okuholela ekudalweni kwama-ejenti okwelapha asebenza kahle kakhulu.
Ngaphezu kokusetshenziswa kwayo kukhemikhali yezokwelapha, i-2-Fluoro-3-iodopyridine nayo ibalulekile kusayensi yezinto. Izakhiwo zayo ze-elekthronikhi eziyingqayizivele ziyenza ibe ikhandidethi lokuhlanganiswa kwezinto ezithuthukisiwe, okuhlanganisa ama-semiconductors e-organic kanye nodayi. Njengoba isidingo sezinto ezintsha siqhubeka sikhula, le nhlanganisela igqama njengengxenye ebalulekile ekuthuthukisweni kobuchwepheshe besizukulwane esilandelayo.
I-2-Fluoro-3-iodopyridine yethu ikhiqizwa ngaphansi kwezinyathelo eziqinile zokulawula ikhwalithi ukuze kuqinisekiswe ukuhlanzeka okuphezulu nokungaguquguquki, okuyenza ifaneleke kokubili ucwaningo kanye nezicelo zezimboni. Kungakhathaliseki ukuthi ungumcwaningi wezemfundo noma uchwepheshe embonini yezemithi, le nhlanganisela iyithuluzi elibalulekile lamaphrojekthi akho.
Vula amandla ocwaningo lwakho nge-2-Fluoro-3-iodopyridine (CAS# 113975-22-7) – inhlanganisela ehlanganisa ikusasa lokuqamba okusha kwamakhemikhali. Hlola ama-horizons amasha ku-synthesis futhi uthole amathuba alindile ngalekhemikhali emangalisayo.
Isingeniso
Sethula i-Sebacic Acid - ikristalu eguquguqukayo, emhlophe ebabazekayo eye yanda ngokuduma phakathi neminyaka edlule, ngenxa yobubanzi bayo bezinhlelo zokusebenza kuzo zonke izimboni eziningi. I-Sebacic acid iyi-dicarboxylic acid enefomula yamakhemikhali engu-HOOC(CH2)8COOH futhi iyancibilika emanzini, etshwaleni, naku-ether. Le acid ephilayo ivame ukutholakala embewini kawoyela we-castor, futhi ingenye yezinto ezibalulekile ezisetshenziswa embonini yamakhemikhali.
I-Sebacic acid isetshenziswa kakhulu njengempahla eluhlaza ye-sebacate plasticizer kanye ne-nylon molding resin. Lokhu kungenxa yekhono layo lokuthuthukisa kakhulu ukunwebeka nokuguquguquka kwama-polymer ahlukahlukene ngaphandle kokuphazamisa ukusebenza noma ukuzinza kwawo. Ithuthukisa ukumelana namazinga okushisa adlulele, ukusikeka, nokubhoboza kanye nokuthuthukisa amandla aqinile nacindezelayo wezinto zenayiloni. Ngenxa yalokho, iye yamukelwa kabanzi embonini yepulasitiki.
I-Sebacic acid iphinde isetshenziswe kakhulu ekukhiqizeni amafutha okugcoba amelana nezinga lokushisa eliphezulu. Ngenxa yokuhambisana kwayo nezindawo ezisezingeni eliphezulu, isebenza njengesisekelo esihle kakhulu sezigcobo embonini yezimoto kanye ne-aerospace. Imvelo yayo eqinile ngokushisa ivumela ukubekezelelana okukhulu ekushiseni okuphezulu ngokungqubuzana okuncishisiwe nokuguga kuyilapho iqinisekisa ukwethembeka nokusebenza.
Enye indawo lapho i-sebacic acid ithola khona ukusetshenziswa iwukwenza izinto ezinamathelayo namakhemikhali akhethekile. Isetshenziswa kakhulu ezintweni ezinamathelayo ngenxa yokumanzisa kwayo okuhle nokungena kwayo. I-Sebacic acid isetshenziselwa ukukhiqiza izinto ezinamathelayo ezisebenza kahle kakhulu ngoba ingathuthukisa izakhiwo zokunamathisela ze-adhesive.
I-Sebacic acid nayo isetshenziswa njenge-corrosion inhibitor ekwelapheni kwamanzi nasekukhiqizeni uwoyela. Ukusebenza kahle kwayo ekuvimbeleni ukugqwala kanye ne-oxidation kuyenza ilungele amapayipi nezinye izinto ezisetshenziselwa ukuthutha nokucubungula uwoyela negesi yemvelo.
Ngenxa yohlamvu lwayo lwekristalu olumhlophe, i-sebacic acid ingabonakala kalula kwamanye amakhemikhali. Lokhu kwenza kube ukufakwa okukhangayo embonini yezemithi njenge-excipient. Ingasetshenziswa njenge-diluent, binder kanye ne-lubricant ekwenzeni amafomu emithamo ahlukene njengamaphilisi, amaphilisi, nama-suppositories.
Sengiphetha, ukusebenzisa izinto ezihlukahlukene kwe-sebacic acid kanye nohlu olubanzi lwezinhlelo zokusebenza kuyenza ibe umkhiqizo okhangayo kakhulu ongasetshenziswa kuzo zonke izimboni eziningi kusukela kwezezimoto kanye ne-aerospace kuye kokukhiqizwa kwemithi namakhemikhali. Ukuzinza kwayo ngaphansi kwezimo ezimbi kakhulu kuyenza ibaluleke kakhulu ezimbonini eziningi ezihlanganisa ipulasitiki, uwoyela, igesi, nokwelashwa kwamanzi, kuyilapho amandla ayo okuthuthukisa ukusebenza kwama-polymers ekhombisa ukubaluleka kwawo. Sekukonke, i-sebacic acid iyisivikelo sokwakha esibalulekile semikhiqizo eminingana eseyibalulekile empilweni yesimanje.
