Ubuninzi be-Triethylamine: Ukuqonda kunye nezicelo
I-Triethylamine (TEA) yikhompawundi ebalulekileyo ye-organic esetyenziswa ngokubanzi kwimichiza, amayeza, kunye namashishini edayi. Ukuqonda iimpawu ezibonakalayo ze-triethylamine, ngokukodwa ukuxinana kwayo, kubalulekile ekusebenziseni ngokufanelekileyo kunye nokulawula okukhuselekileyo. Kweli nqaku, siza kuhlalutya iinkcukacha ezicacileyo malunga nokuxinana kwe-triethylamine kunye nefuthe layo kwizicelo ezisebenzayo.
Yintoni i-triethylamine?
I-Triethylamine yikhompawundi ye-amine ephakamileyo eqhelekileyo kunye ne-chemical formula (C6H{15}N). Kwiqondo lobushushu begumbi, i-triethylamine iyilwelo olungenambala kunye nevumba elinamandla le-ammonia kwaye liguquguquka kakhulu. Ekubeni i-triethylamine iyikhompawundi esisiseko, isetyenziswa ngokubanzi kwi-organic synthesis, i-asidi yegesi yokufunxa, i-pesticides, i-pharmaceuticals, iiplastiki kunye namanye amashishini. Ukuqonda iimpawu ezibonakalayo ze-triethylamine, ngakumbi "i-triethylamine density", ngundoqo ekuqondeni indlela le khemikhali isebenzisana ngayo nezinye izinto.
Iimpawu eziphambili zeTriethylamine Density
Ubuninzi be-triethylamine yenye yezona zinto zibaluleke kakhulu kwiimpawu zayo zomzimba kwaye zichaphazela ngokuthe ngqo ukuphatha nokugcinwa kwayo kwizicelo zoshishino. Ubuninzi be-triethylamine bumalunga ne-0.726 g/cm³ (20°C), ekhaphukhaphu xa ithelekiswa noxinaniso lwamanzi. Oku kuthetha ukuba i-triethylamine idada emanzini xa ixutywe namanzi, ipropathi enokuthi isetyenziswe ngexesha lokwahlulwa kwesisombululo kunye nokusabela kweekhemikhali.
Ubuninzi be-triethylamine buhambelana ngokusondeleyo nobushushu kwaye buyancipha xa ubushushu bunyuka. Ukuqonda oku kubalulekile ekusebenzeni kwe-triethylamine kumaqondo obushushu aphezulu, njengoko kunokuchaphazela ukuhanjiswa koxinaniso lwee-reactants kunye namazinga okuphendula. Ngoko ke, ekusebenzeni, iimeko zokushisa kufuneka zilawulwe ukuqinisekisa ukuzinza kwezinto eziphathekayo.
Impembelelo yobuninzi be-triethylamine kwizicelo eziphathekayo
Ukukhetha i-solvent kunye nolawulo lokuphendula: Ekubeni ubuninzi be-triethylamine buphantsi kunezinye izinyibilikisi ezininzi zezinto eziphilayo, oku kuya kuchaphazela ukusebenza kwayo ekuxubeni nasekuphenduleni. Xa ulungiselela izisombululo zokusabela, ukwazi ukuxinana kwe-triethylamine kunokunceda ukubala ngokuchanekileyo ukuxinana kwesisombululo kunye nokuqinisekisa ukuba ukusabela kuqhubeka njengoko kulindelekile. Uxinaniso oluphantsi lwe-triethylamine lwenza ukuba luchaphazeleke kwi-volatilisation, ngoko ke ingqwalasela eyodwa kufuneka ihlawulwe kwiilahleko zokuguquguquka ngexesha lokuphatha, ngakumbi kwiindawo ezivulekileyo ezinomoya olungileyo.

Ukugcinwa kunye nokhuseleko lwezothutho: Ngenxa yobuninzi bayo obuphantsi kunye nokuguquguquka, i-triethylamine kufuneka igcinwe kwaye ihanjiswe phantsi kweemeko ezilawulwa ngokungqongqo. Kucetyiswa ukuba kusetyenziswe izikhongozeli ezinomsebenzi wokutywina kakuhle kwaye uzigcine kwindawo epholileyo, enomoya opholileyo, ukuphepha ukukhanya kwelanga kunye neendawo zokushisa eziphezulu, ukuze kuthintelwe izikhongozeli ukuba zingaphuki okanye zivuze ngenxa yokwanda koxinzelelo.

Ukhuseleko lokusingqongileyo kunye nokhuseleko: I-Triethylamine inevumba elibi elicaphukisayo kwaye inetyhefu ebantwini, kwaye umphunga wayo unokubangela ukucaphuka kwamehlo, indlela yokuphefumula kunye nesikhumba. Ngoko ke, izixhobo ezifanelekileyo zokukhusela ezifana neeglasi zokukhusela, iiglavu kunye nemaski kufuneka zigqitywe ngexesha lokusebenza ukuqinisekisa ukhuseleko lomsebenzisi. Ulwazi lokuxinana kwe-triethylamine lunokuba luncedo kwimeko yokuchitheka, umz. ukuqokelela nokulahla ulwelo oluchithekileyo kusetyenziswa iimpawu zayo zokuxinana.

Impembelelo yoxinaniso lwe-triethylamine kwishishini
Kwimveliso yeekhemikhali, ubuninzi be-triethylamine buchaphazela ukuyila kunye nokulungiswa kweenkqubo ezininzi. Ngokomzekelo, kwi-synthesis ye-pharmaceutical intermediates, iipropati ezibonakalayo ze-triethylamine kufuneka zithathelwe ingqalelo ekuyilweni kwe-reactor kunye nokusekwa kwesantya esishukumisayo. Ngenxa yobuninzi bayo obuphantsi, ukuvuselela okukhethekileyo kunokufuneka ukuxuba ukusabela ukuqinisekisa ukusabalalisa okufanayo kwee-reactants. Ekuphathweni kwamanzi amdaka kunye nokukhutshwa kwegesi yokukhupha, iimpawu zoxinaniso ze-triethylamine nazo zichaphazela ukhetho lweenkqubo zokuhlukana, ezifana nokuyila iikholomu zokuhlukana kwe-gas-liquid.
Ukuqukumbela
Ukuqonda "i-triethylamine density" kunye neempawu zayo zomzimba ezinxulumene nazo zibalulekile ekusebenziseni ngokufanelekileyo kunye nokulawulwa kwe-triethylamine. Ayichaphazeli nje kuphela ulawulo oluchanekileyo lwe-chemical reaction, kodwa ibeka iimfuno ezicacileyo zokugcina, ukuthutha kunye nokhuseleko. Kwizicelo ezisebenzayo, iimpawu zoxinaniso lwe-triethylamine kufuneka zithathelwe ingqalelo ukuphuhlisa iinkqubo zesayensi kunye nengqiqo yokusebenza ukuqinisekisa ukuveliswa okusebenzayo nokukhuselekileyo.
