Benzeneacetonitrile （CAS # 140-29-4）

Benzeneacetonitrile （CAS # 140-29-4）

Benzeneacetonitrile, CAS nimero 140-29-4, irihariye mubice byinshi bya chimie.
Uhereye ku miterere yimiti, igizwe nimpeta ya benzene ihujwe nitsinda rya acetonitrile. Impeta ya benzene ifite sisitemu nini π bond conjugation sisitemu, itanga molekile itajegajega hamwe nogukwirakwiza ibicu bidasanzwe bya electron, bigatuma igira impumuro nziza. Itsinda rya acetonitrile ryerekana polarite ikomeye na reaction ya groupe ya cyano, ituma molekile yose itagira gusa inertness ugereranije na hydrophobicity yazanwe nimpeta ya benzene, ariko ikanatanga amahirwe menshi yo guhuza ibinyabuzima kuko itsinda rya cyano rishobora kugira uruhare muburyo butandukanye ya nucleophilique na electrophilique reaction. Mubisanzwe bigaragara nkibara ritagira ibara ryijimye ryumuhondo mubigaragara, kandi ubu buryo bwamazi bworoshye bwo kwimura no kwezwa binyuze mubikorwa bisanzwe nko gutandukanya amazi no gutobora muri laboratoire na synthesis. Kubijyanye no gukemuka, birashobora kuba byiza gushonga mumashanyarazi kama, nka ether, chloroform nizindi zidafite inkingi ya polar cyangwa intege nke za polar, mugihe mubishobora gukemuka mumazi ari bibi, bifitanye isano rya bugufi na polarike, kandi ikanagena guhitamo kuyikoresha. muri sisitemu zitandukanye.
Nibintu byingenzi hagati yimikorere ya synthesis. Ukurikije imiterere yabyo, imiti itandukanye yimiti irashobora kubaho kugirango yubake ibintu bigoye. Kurugero, binyuze muri hydrolysis reaction ya cyanogroup, aside ya fenylacetike irashobora gutegurwa, ikoreshwa murwego rwa farumasi muguhuza imiti itandukanye, nko guhindura urunigi kuruhande rwa antibiotike ya penisiline; Mu nganda z ibirungo, nibikoresho byingenzi byo gutegura ibirungo byindabyo nka roza na lili yikibaya. Byongeye kandi, kugabanya reaction ya cyano irashobora no gukoreshwa kugirango ihindurwe mungingo ya benzylamine, kandi ibikomoka kuri benzylamine bikoreshwa cyane mubijyanye n’imiti yica udukoko n’amabara, kandi bikoreshwa mugutezimbere imiti yica udukoko twangiza cyane, amarangi afite amabara meza kandi maremare kwihuta.
Kubijyanye nuburyo bwo gutegura, acetophenone ikoreshwa nkibikoresho fatizo mu nganda, kandi itegurwa nintambwe ebyiri zifata okisime na dehidrasi. Ubwa mbere, acetophenone ifata hamwe na hydroxylamine kugirango ikore oxyde ya acetophenone, hanyuma ihindurwamo Benzeneacetonitrile ikorwa na dehydrator, kandi muribwo buryo, abashakashatsi bakomeje kunoza imiterere yimyitwarire, harimo guhindura ubushyuhe bwa reaction no kugenzura ingano ya dehidrator, bityo nko kuzamura umusaruro, kugabanya ikiguzi, no kwemeza ko hakenewe umusaruro munini. Hamwe no guhanga udushya twa tekinoroji ya synthesis, kunoza inzira ya synthesis ya Benzeneacetonitrile yibanda ku kurengera ibidukikije n’ubukungu bwa atome, guharanira kugabanya imyuka ihumanya ikirere, kunoza imikoreshereze y’umutungo, kugira uruhare mu iterambere rirambye ry’inganda z’imiti, no kurushaho kwagura ikoreshwa ryayo ubushobozi.
