Ntho e belang ea Ethylene Glycol le tlhahlobo ea thepa ea eona ea lik'hemik'hale
Ka indasteri ea lik'hemik'hale, ethylene glycol (Ethylene Glycol) ke lisebelisoa tsa bohlokoa tsa lik'hemik'hale tse sebelisoang haholo libakeng tse sa tšoaneng tse kang antifreeze le tlhahiso ea resin. Ho utloisisa thepa ea physicochemical ea Ethylene Glycol, haholo-holo ntlha ea eona e belang, ke ea bohlokoa bakeng sa ts'ebeliso ea eona indastering. Sehloohong sena, ntlha e belang ea ethylene glycol le lintlha tse amanang le eona tse susumetsang li tla tšohloa ka ho qaqileng.
Lintho tsa Motheo tsa Ethylene Glycol le Ntlha ea eona e Belang
Ethylene glycol ke mokelikeli o se nang 'mala, o sa nkheng, o monko o monate o nang le foromo ea lik'hemik'hale C₂H₆O₂. Joaloka diol, ethylene glycol e na le hygroscopicity e matla le thepa e ntle ea ho qhibiliha. Sebaka se belang sa ethylene glycol ke 197.3°C. Boleng bona, bo lekantsoeng ka khatello ea sepakapaka, bo bonahatsa botsitso ba sebopeho sa eona sa molek'hule le matla a maqhama a eona a intermolecular hydrogen.
Lintlha tse amang ntlha e belang le bohlokoa ba eona ba indasteri
Sebaka se belang sa ethylene glycol se susumetsoa ke lintlha tse 'maloa. Ho tlamahanngoa ha hydrogen mohahong oa limolek'hule ho na le phello e kholo sebakeng se belang. Molek'hule ea ethylene glycol e na le lihlopha tse peli tsa hydroxyl (-OH), tse hokahaneng ka litlamo tsa hydrogen, ho etsa hore matla a intermolecular a ethylene glycol a be matla 'me a lebisa sebakeng se batlang se bela. Boima ba molek'hule ea ethylene glycol le eona e ama ntlha ea eona e belang, ka litekanyo tse kholo tsa limolek'hule tse hlokang matla a mangata bakeng sa ho fetoha mouoane.
Lits'ebetsong tsa indasteri, ntlha e belang ea ethylene glycol e na le tšusumetso e kholo ts'ebetsong ea eona e le solvent, coolant le lihlahisoa tse ling. Ka mohlala, ntlha e phahameng ea ho bela e etsa hore glycol e be e tsitsitseng le e fokolang mocheso o phahameng, kahoo e netefatsa hore e sebetsa hantle ho li-coolants le antifreeze.
Litlhokomelo ka tšebeliso e sebetsang
Ha u sebelisa ethylene glycol, tlhokomelo e lokela ho lefshoa ho sebelisana ha ntlha ea eona e belang le lintho tse ling. Ka mohlala, ka metsoako kapa litharollo tse tsoakiloeng, lintho tse ling li ka ama ntlha e belang ea ethylene glycol 'me kahoo thepa ea ho qetela ea sehlahisoa. Tsebo ea ntlha e belang ea ethylene glycol e ka boela ea thusa ho ntlafatsa mekhoa ea tlhahiso ea indasteri, joalo ka taolo ea mocheso nakong ea distillation le mahloriso.
Ka bokhutšoanyane, kutloisiso ea ntlha e belang ea ethylene glycol e bohlokoa bakeng sa ts'ebeliso ea eona ea indasteri. Ka ho utloisisa thepa ena ea 'mele ea ethylene glycol, ts'ebetso ea eona tlhahiso le ts'ebeliso e ka laoloa hamolemo ho ntlafatsa boleng le botsitso ba sehlahisoa.
