Falanqaynta Faahfaahsan ee Barta Karkari ee Triethylamine
Triethylamine (TEA marka la soo gaabiyo) waa iskudhis dabiici ah oo caadi ah oo ka tirsan qaybta aminiga ee kiimikooyinka. Waxaa si weyn looga isticmaalaa warshado badan sida dawooyinka, sunta cayayaanka, midabada, dareeraha iyo wixii la mid ah. Kiimikooyinka caadiga ah ee la isticmaalo, sifooyinka jireed ee Triethylamine, gaar ahaan barta karkaraya, ayaa ah cabbirro u baahan in si sax ah loo fahmo oo loo xakameeyo habab kiimiko badan. Warqadan, waxaan si faahfaahsan uga hadli doonaa barta karkarinta ee triethylamine, falanqaynta sababaha physicochemical ee ka dambeeya, iyo muhiimada ay u leedahay codsiyada la taaban karo.
Dulmarka barta karkarinta ee triethylamine
Barta karkarinta ee triethylamine waa 89.5°C (193.1°F), kaas oo ah kulaylkeeda karkaraya cadaadiska jawiga caadiga ah (1 atm). Barta karkaraya waa heerkulka uu cadaadiska uumiga dareeruhu la mid yahay cadaadiska dibadda, taasoo la macno ah in heerkulkan triethylamine uu ka beddelo xaalad dareere ah una beddelo xaalad gaseous ah. Barta karkarinta waa hanti jireed oo muhiim ah oo walax ah waxayna lagama maarmaan u tahay fahamka habdhaqanka triethylamine ee xaalado kala duwan.
Waxyaabaha saameeya barta karkarinta ee triethylamine
Barta karkarinta ee triethylamine waxaa inta badan saameeya qaab dhismeedka molecular iyo xoogagga intermolecular. Triethylamine waa amin sare oo qaab dhismeedkiisa molecular ka kooban yahay atamka nitrogen oo ku dheggan saddex kooxood oo ethyl ah. Sababtoo ah waxaa jira hal lammaane oo keli ah oo elektaroonik ah oo ku yaal atamka nitrogen ee ku jira molecule triethylamine, ma fududa triethylamine inay sameeyaan bonds hydrogen. Tani waxay ka dhigaysaa xoogagga isku-dhafan ee triethylamine inta badan xoogagga van der Waals, kuwaas oo aad u liita. Natiijo ahaan, barta karkarinta ee triethylamine waa mid hooseeya.
Silsilada hydrocarbon ee ku jira molecule triethylamine waa xoogaa hydrophobic, taas oo sidoo kale saameyn ku leh barta karkarinta. Triethylamine waxay leedahay miisaan kelli ah oo dhexdhexaad ah marka loo eego aminyada kale ee la midka ah, taas oo qayb ahaan sharraxaysa barta karkarinta hoose. Isku darka qaab dhismeedka molecular iyo xoogagga intermolecular ee triethylamine ayaa go'aamiya barta karkarinta ee 89.5 ° C. Barta karkarinta ee triethylamine sidoo kale waa shaqo ka mid ah qaabdhismeedka molecular ee aminka.
Muhiimadda barta karkarinta ee triethylamine ee codsiyada warshadaha
Waa muhiim in la fahmo oo la xakameeyo barta karkarinta ee triethylamine ee habka wax soo saarka kiimikada. Maadaama barta karkarinta ee triethylamine ay ku dhowdahay 90 ° C, kala saarid hufan iyo nadiifinta triethylamine waxaa lagu gaari karaa iyadoo la hagaajinayo heerkulka inta lagu jiro habka falcelinta iyo kala-soocidda. Tusaale ahaan, inta lagu jiro kala-soocidda, si sax ah loo xakameeyo heerkulka u dhow barta karkarinta ee triethylamine waxay si wax ku ool ah uga sooci kartaa xeryahooda kale ee leh dhibco karkarinta kala duwan. Ogaanshaha barta karkarinta ee triethylamine waxay sidoo kale muhiim u tahay hawlgalka badbaadada leh si looga fogaado khasaaraha aan loo baahnayn ama khataraha badbaadada sababtoo ah heerkulka xad dhaafka ah.
Gabagabo
Triethylamine waxay leedahay barta karkarinta ee 89.5 ° C. Hantidan jireed waxaa lagu go'aamiyaa qaab-dhismeedkeeda molecular iyo xoogagga intermolecular. Warshadaha kiimikada, xakamaynta saxda ah ee barta karkarinta ee triethylamine ayaa muhiim u ah wax soo saarka iyo badbaadada. Fahamka barta karkarinta ee triethylamine ma aha oo kaliya inay caawiso si kor loogu qaado habka wax soo saarka, laakiin sidoo kale waxay bixisaa hagitaan muhiim ah oo ku saabsan hawlgallada la taaban karo.
