Uhlalutyo lwendima ebalulekileyo yeSodium Cyanide kuShishino loShishino

intshayelelo

Sodium i-cyanide (NaCN) yikhemikhali enetyhefu kakhulu. Nangona kunjalo, ukusetyenziswa kwayo kwintsimi yoxubo-mayeza kube negalelo elikhulu kwimpilo yabantu. Njengesixhobo esiphambili kwi-organic synthesis, Isodium cyanide ithatha inxaxheba kwizinto ezithile Ukuphendula kweMichizas kwaye isebenza njengelitye lembombo ekwakheni iintlobo ngeentlobo zeemolekyuli zamachiza. Eli nqaku liza kuhlalutya indima yalo ephambili kwi Icandelo lezamayeza kunye nayo Ulawulo loKhuseleko.

I. "I-Molecular Scalpel" njengeSynthetic Intermediate

Ixabiso elingundoqo le sodium cyanide ilele kwiqela lecyano (-CN) libonelela. Kwi-synthesis yeziyobisi, iqela le-cyano linokuthatha inxaxheba kumanyathelo aphambili ngezi ndlela zilandelayo:

1.Ukwaziswa kwamaQela aSebenzayo aneNitrogen: Iqela le-cyano linokuthi lifakwe i-hydrolyzed kwiqela le-carboxylic acid (-COOH) okanye lincitshiswe kwiqela le-amino (-NH₂). La maqela ziindawo ezisebenzayo zamachiza amaninzi, anje nge-antibiotics kunye namachiza achasene nomhlaza.

2.Ukwakhiwa kwaMathambo aMathambo eMolekyuli: Ngokomzekelo, i-synthesis ye-vitamin B12 ixhomekeke kukulungelelaniswa kweqela le-cyano kunye ne-cobalt ions; ukuhlanganiswa kwezinye i-β-blockers (ezifana nepropranolol) zifuna Isodium cyanide ukwazisa ikhonkco elisecaleni elingundoqo.

ityala: Kwi-synthesis ye-precursor ye-anti-cancer drug 5-fluorouracil, i-sodium cyanide ibandakanyeka ekwakhiweni kwendandatho ye-pyrimidine, echaphazela ngokuthe ngqo umsebenzi wokulwa ne-tumor yeyeza.

II. Ukuqhuba iintshukumo ezingundoqo zeMichiza

1.Cyanidation Reaction:

Ngokusebenzisa i-nucleophilic substitution reaction (efana ne-SN2), iqela le-cyano lingathatha indawo ye-athomu ye-halogen ye-halogenated hydrocarbon ukwenza i-nitrile compound. Ngokomzekelo, i-α-chlorovaleronitrile, i-intermediate esetyenziswa kwi-synthesis ye-antimalarial drug chloroquine.

2.Strecker Synthesis:

I-sodium cyanide iphendula kunye ne-aldehyde / i-ketone kunye ne-ammonia ukwenza i-α-amino nitrile, eyenziwa nge-hydrolyzed ukufumana i-amino acid (efana ne-alanine), isiseko sezinto ezisisiseko kwiziyobisi zeprotheni.

3.Intshukumo yebhayisekile:

Iqela le-cyano lithatha inxaxheba kwi-intramolecular cyclization ukwenza i-nitrogen-containing heterocycle (njenge-pyridine kunye ne-pyrimidine). Izakhiwo ezinjalo zifumaneka ngokubanzi kwiziyobisi ezichasayo (ezifana ne-oseltamivir) kunye neziyobisi ezichasayo ze-AIDS.

III. Ulawulo loMgangatho kunye noLawulo loKhuseleko

Nangona i-sodium cyanide inetyhefu kakhulu, ukusetyenziswa kwayo kumashishini amayeza kulawulwa ngokungqongqo:

1.Ulawulo olupheleleyo lwenkqubo:

Ukususela ekuthengeni, ukugcina ukusetyenziswa, kufuneka kuhambelane "neMimiselo yoLawulo loKhuseleko lweMichiza enobungozi". Amanyathelo afana nomntu ophindwe kabini ukutshixa kunye nokujonga ixesha lokwenyani zamkelwe.

2.UPhuculo lweNkqubo:

I-teknoloji efana ne-microchannel reactors isetyenziselwa ukunciphisa umngcipheko we-sodium cyanide exposure, kwaye kwangaxeshanye kuphuculwe ukusebenza kakuhle kokuphendula kunye nokukhetha.

3.Uphononongo lweeTechnologies ezizezinye:

Izindlela eziluhlaza ezifana ne-biocatalysis (ezifana ne-nitrile hydratase) kunye ne-electrochemical cyanidation zitshintsha ngokuthe ngcembe iinkqubo zemveli zokunciphisa ingozi yokusingqongileyo.

IV. IiNdlela zexesha elizayo: Ukulungelelanisa uKhuseleko kunye nokusebenza kakuhle

1.Ukuqhelaniswa neChemistry eluhlaza:

Phuhlisa iindlela zokusabela ezingena-cyanide. Ngokomzekelo, sebenzisa i-metal-organic frameworks (MOFs) ukuze ubhengeze iqela le-cyano, ukunciphisa ukusetyenziswa kwezinto eziluhlaza.

2.UkuBeka esweni okukrelekrele:

Hlanganisa i-AI kunye ne-sensor technologies ukujonga intsalela ye-cyanide kwinkqubo yokuphendula ngexesha langempela, ukuqinisekisa ukucoceka kunye nokhuseleko lwamachiza.

isiphelo

I-sodium cyanide idlala "indima emibini" kwishishini loxubo mayeza: zombini zingumqhubi ophambili wokuqalwa kweziyobisi kunye nento eyingozi efuna ukuphathwa ngononophelo. Ngokwenza izinto ezintsha zetekhnoloji kunye nolawulo olungqongqo, ukusetyenziswa kwayo kuphuhlisa ukuya kwicala elikhuselekileyo nelisebenza ngokufanelekileyo, libonelela ngenkuthazo eqhubekayo kuluntu ukuba loyise izifo.
