Benzeneacetonitrile (CAS#140-29-4)

Benzeneacetonitrile (CAS#140-29-4)

I-Benzeneacetonitrile, inombolo ye-CAS 140-29-4, iyingqayizivele kwiinkalo ezininzi zekhemistri.
Ukusuka kwisakhiwo sekhemikhali, yenziwe ngeringi ye-benzene edityaniswe neqela le-acetonitrile. Iringi ye-benzene inenkqubo enkulu yokudibanisa i-π bond, enika imolekyuli uzinzo kunye nokuhanjiswa kwelifu le-electron eyodwa, eyenza ibe nevumba elithile. Iqela le-acetonitrile lazisa i-polarity eyomeleleyo kunye ne-reactivity yeqela le-cyano, elenza ukuba i-molecule yonke ingabi ne-inertness ehambelanayo kunye ne-hydrophobicity eziswa yi-benzene ring, kodwa ibonelela ngamathuba atyebileyo kwi-organic synthesis kuba iqela le-cyano lingathatha inxaxheba kwiindidi ezahlukeneyo. ukusabela kwe-nucleophilic kunye ne-electrophilic. Idla ngokubonakala njengolwelo olungenambala ukuya kokukhanya olutyheli ngenkangeleko, kwaye le fomu yolwelo ilungele ukudluliselwa kunye nokucocwa ngokusebenzisa imisebenzi yesiqhelo efana nokwahlulwa kolwelo kunye nokuxutywa kwe-distillation kwilabhoratri kunye neemeko ze-industrial synthesis. Ngokubhekiselele kwi-solubility, inokunyibilika ngcono kwi-organic solvents, njenge-ether, i-chloroform kunye nezinye izinyibiliki ezingeyopolar okanye ezibuthathaka, ngelixa i-solubility yamanzi ihlwempuzekile, ehambelana ngokusondeleyo kwi-molecular polarity, kwaye ikwamisela ukukhethwa kwayo kwesicelo. kwiinkqubo ezahlukeneyo zokusabela.
Yinto ebalulekileyo ephakathi kwizicelo ze-organic synthesis. Ngokusekelwe kwiimpawu zabo zesakhiwo, iintlobo ezahlukeneyo zeekhemikhali zinokuthi zenzeke ukwakha iikhompawundi ezinzima. Ngokomzekelo, ngokusebenzisa i-hydrolysis reaction ye-cyanogroup, i-phenylacetic acid inokulungiswa, esetyenziswa kwintsimi yamachiza ukudibanisa iintlobo ezahlukeneyo zeziyobisi, ezifana nokuguqulwa kwekhonkco le-penicillin antibiotics; Kushishino lweziqholo, yeyona nto iphambili ekulungiseni iziqholo zeentyatyambo ezifana neerozi kunye nenyibiba yentlambo. Ukongeza, ukusabela kokunciphisa i-cyano kungasetyenziselwa ukuyiguqula ibe yi-benzylamine compounds, kunye ne-benzylamine derivatives isetyenziswa ngokubanzi kwintsimi ye-pesticides kunye nedayi, kwaye isetyenziselwa ukuphuhlisa i-pesticides ephezulu, iidayi ezinemibala eqaqambileyo kunye nephezulu. ukukhawuleza.
Ngokumalunga nendlela yokulungiselela, i-acetophenone isoloko isetyenziswa njengento ekrwada kwishishini, kwaye ilungiselelwe ukusabela ngamanyathelo amabini e-oxime kunye nokuphelelwa ngamanzi emzimbeni. Okokuqala, i-acetophenone isabela kunye ne-hydroxylamine ukwenza i-acetophenone oxime, ethi emva koko iguqulwe ibe yi-Benzeneacetonitrile phantsi kwesenzo se-dehydrator, kwaye kwinkqubo, abaphandi baqhubeka nokwandisa iimeko zokuphendula, kuquka ukulungelelanisa ubushushu bokuphendula kunye nokulawula ubungakanani be-dehydrator, ngoko ke. njengokuphucula isivuno, ukunciphisa iindleko, kunye nokuqinisekisa imfuno yemveliso enkulu. Ngokuqulunqwa kwetekhnoloji ye-organic synthesis, ukulungiswa kwendlela yokudibanisa ye-Benzeneacetonitrile igxile ekukhuselweni kwendalo kunye noqoqosho lwe-athomu, ukuzama ukunciphisa ukukhutshwa kwenkunkuma, ukuphucula ukusetyenziswa kobutyebi, ukufaka isandla kuphuhliso oluzinzileyo lweshishini lemichiza, kunye nokwandisa ukusetyenziswa kwayo. ezinokubakho.
