A cikin wannan takarda, za mu tattauna batun tafasa na triethylamine daki-daki, nazarin dalilan physicochemical a baya, da mahimmancinsa a aikace-aikace masu amfani.
Bayanin wurin tafasa na triethylamine
Wurin tafasa na triethylamine shine 89.5°C (193.1°F), wanda shine zafin zafinsa a daidaitaccen yanayin yanayi (1 atm). Wurin tafasa shine yanayin zafin da tururi matsa lamba na ruwa yayi daidai da matsa lamba na waje, ma'ana cewa a wannan zafin jiki triethylamine yana canzawa daga yanayin ruwa zuwa yanayin gaseous. Tushen tafasa shine muhimmin kayan jiki na abu kuma yana da mahimmanci don fahimtar halayen triethylamine a ƙarƙashin yanayi daban-daban.
Abubuwan da ke shafar wurin tafasa na triethylamine
Wurin tafasa na triethylamine yana rinjayar tsarinsa na kwayoyin halitta da kuma dakarun intermolecular. Triethylamine shine amine na uku wanda tsarin kwayoyin halitta ya ƙunshi atom na nitrogen wanda ke haɗe zuwa ƙungiyoyin ethyl guda uku. Domin akwai guda ɗaya kaɗai na electrons akan nitrogen atom a cikin kwayoyin triethylamine, ba shi da sauƙi ga triethylamine don samar da haɗin gwiwar hydrogen. Wannan ya sa rundunonin ƙwayoyin cuta na triethylamine galibi van der Waals sojojin, waɗanda ba su da ƙarfi. A sakamakon haka, wurin tafasa na triethylamine yana da ƙananan ƙananan.
Sarkunan hydrocarbon a cikin kwayoyin triethylamine suna da ɗan hydrophobic, wanda kuma yana da tasiri akan wurin tafasa. Triethylamine yana da matsakaicin nauyin kwayoyin halitta idan aka kwatanta da sauran nau'in amines masu kama da juna, wanda wani bangare ya bayyana ma'anar tafasar sa. Haɗin tsarin kwayoyin halitta da ƙarfin intermolecular na triethylamine yana ƙayyade wurin tafasarsa na 89.5 ° C. Wurin tafasa na triethylamine kuma aiki ne na tsarin kwayoyin halittar amine.
Muhimmancin wurin tafasa na triethylamine a aikace-aikacen masana'antu
Yana da mahimmanci a fahimta da sarrafa wurin tafasa na triethylamine a cikin tsarin samar da sinadaran. Tun lokacin tafasawar triethylamine yana kusa da 90 ° C, za a iya samun ingantaccen rabuwa da tsarkakewa na triethylamine ta hanyar daidaita yanayin zafin jiki yayin aiwatarwa da tsarin rabuwa. Alal misali, a lokacin distillation, daidai sarrafa zafin jiki kusa da tafasar batu na triethylamine iya yadda ya kamata raba shi da sauran mahadi tare da daban-daban tafasas. Sanin wurin tafasa na triethylamine shima yana da mahimmanci don aiki mai aminci don gujewa asarar da ba dole ba ko haɗarin aminci saboda yawan zafin jiki.
Kammalawa
Triethylamine yana da wurin tafasa na 89.5 ° C. An ƙaddara wannan dukiya ta zahiri ta hanyar tsarin kwayoyin halitta da kuma ƙarfin intermolecular. A cikin masana'antar sinadarai, daidaitaccen sarrafa wurin tafasa na triethylamine yana da mahimmanci don yawan aiki da aminci. Fahimtar wurin tafasa na triethylamine ba kawai yana taimakawa wajen inganta tsarin samarwa ba, har ma yana ba da jagora mai mahimmanci a cikin ayyuka masu amfani.
