Kwicandelo le-organic chemistry, ukubaluleka kwezinto ezinciphisa i-athomu akunakugxininiswa kakhulu. Phakathi kweekhompawundi ezahlukeneyo ezisetyenziselwa le njongo, i-acetyl chloride ivelele ngeempawu zayo ezikhethekileyo kunye nokuguquguquka kwayo. Le blogi iza kubonelela ngophononongo olujulileyo ngeempawu ze-acetyl chloride, ukusetyenziswa kwayo, kunye nendima yayo ekunciphiseni amaqela asebenzayo e-organic.
Yintoni i-acetyl chloride?
I-acetyl chloride, ifomula yekhemikhali i-CH3COCl, yi-asidi chloride ephuma kwi-acetic acid. Lulwelo olungenambala olunevumba elibi kwaye lusabela kakhulu, ingakumbi xa lusetyenziswa emanzini nasetywala. Olu hlobo lokusabela luyenza ibe yikhompawundi ebalulekileyo kwiindlela ezahlukeneyo zokusabela kweekhemikhali, ingakumbi xa kusenziwa ezinye iikhompawundi zendalo.
Indima ye-acetyl chloride ekunciphiseni i-reaction
Enye yezona zicelo ziphambili zei-acetyl chlorideIsebenza njengearhente yokunciphisa kwikhemistri yendalo. Isebenza kakuhle kakhulu ekunciphiseni i-aldehydes, ii-ketones kunye ne-chlorine phthalides. Ukukwazi ukunciphisa ngokukhetha la maqela asebenzayo kwenza i-acetyl chloride ibe sisixhobo esibalulekileyo kwiikhemistri.
Nciphisa i-aldehydes kunye nee-ketones
Ii-Aldehydes (RCOH) kunye nee-ketones (RCOR) ngamaqela asebenzayo aqhelekileyo kwiikhompawundi ze-organic. Ukuncitshiswa kwala maqela kubalulekile ekuhlanganisweni kwee-alcohols kunye nezinye izinto eziphuma kuzo.I-acetyl chlorideingenza kube lula olu tshintsho ngokunikela ngee-electron, iguqule ngempumelelo iqela le-carbonyl libe liqela le-hydroxyl. Le mpendulo ayisebenzi nje kuphela, kodwa inokunciphisa ngokukhetha amaqela athile asebenzayo ngaphandle kokuchaphazela amanye amaqela asebenzayo kwi-molecule.
Iinaphthalenes ezineklorini
Ii-ophthalone ezine-chlorine lolunye udidi lweekhompawundi ezinokuncitshiswa kusetyenziswa i-acetyl chloride. Ezi khompawundi zihlala zisetyenziswa kwizalathisi ze-pH kunye needayi. Inkqubo yokunciphisa inokutshintsha iipropati zazo, izenze zifaneleke ngakumbi kwizicelo ezithile. Ngokusebenzisa i-acetyl chloride, iingcali zamachiza zinokufezekisa utshintsho olufunekayo ngelixa zigcina ukuthembeka kwesakhiwo siphela.
Iingenelo zokusebenzisa i-acetyl chloride
1. Ukukhetha:Enye yezona nzuzo zibalulekileyo zokusebenzisa i-acetyl chloride njenge-reducing agent kukukhetha kwayo. Ingajolisa kumaqela athile asebenzayo ngaphandle kokuchaphazela amanye amaqela asebenzayo, ivumela ukuguqulwa ngokuchanekileyo kwee-molecules ezintsonkothileyo ze-organic.
2. Ukusebenza kakuhle:Amazinga okusabela aquka i-acetyl chloride adla ngokuba phezulu, nto leyo ebangela ukuba ixesha lokwenziwa kwezinto likhawuleze. Oku kusebenza kakuhle kuluncedo ngakumbi kwizicelo zoshishino apho ixesha kunye neendleko zizinto ezibalulekileyo.
3. Ukuguquguquka:I-Acetyl chloride ingasetyenziswa kwiindlela ezahlukeneyo zokusabela ngaphandle kokunciphisa, kubandakanya i-acylation kunye nokuhlanganiswa kwe-ester. Olu tshintsho lwenza ukuba ibe yikhompawundi exabisekileyo kwibhokisi yezixhobo zekhemistri yendalo.
Amanyathelo okhuseleko
Nangonai-acetyl chlorideyi-reagent enamandla, kufuneka iphathwe ngononophelo. Iyatsha kwaye inokubangela ukutsha okukhulu xa idibana nolusu okanye amehlo. Ukongeza, ikhupha i-hydrochloric acid xa isabela emanzini, nto leyo enokuba yingozi. Iindlela ezifanelekileyo zokhuseleko zibalulekile xa usebenza nale khompawundi, kubandakanya ukusebenzisa izixhobo zokuzikhusela (PPE) kunye nokusebenza kwindawo enomoya ococekileyo.
I-acetyl chlorideyi-compound enomdla kwicandelo le-organic chemistry, ngakumbi njenge-arhente yokunciphisa i-aldehydes, ii-ketones kunye ne-chlorine phthalides. Ukukhetha kwayo, ukusebenza kwayo kakuhle, kunye nokuguquguquka kwayo kwenza ukuba ibe sisixhobo esibalulekileyo kwiingcali zekhemistri. Nangona kunjalo, ukhuseleko luhlala luyinto ephambili xa kuphathwa izinto ezinjalo ezisebenzayo. Njengoko uphando kunye nokusetyenziswa kwe-organic chemistry kuqhubeka nokukhula, i-acetyl chloride ngokuqinisekileyo iya kuqhubeka nokudlala indima ephambili ekuhlanganiseni nasekuguquleni iikhompawundi ze-organic.
