Glycerol, e tsejoang hape e le glycerin kapa propane-1,2,3-triol, ke motsoako oa lintho tse phelang o sebelisoang haholo. Ke mokelikeli o se nang 'mala, o se nang monko, o nang le tatso e monate. Glycerol e na le hygroscopic, ho bolelang hore e hohela le ho tšoara limolek'hule tsa metsi tikolohong e potolohileng. Thepa ena e etsa hore e be motsoako oa bohlokoa lits'ebetsong tse fapaneng tsa indasteri, ho kenyeletsoa litlolo, meriana, lijo le lihlahisoa tsa tlhokomelo ea botho.
Matlo
Glycerol e na le boima ba limolek'hule ba hoo e ka bang 92.09 g/mol. E qhibiliha haholo metsing 'me e na le ntlha ea ho belisa ea 290°C. Motsoako ona o tsebahala ka ho teteana ha oona ho phahameng le tlhaho ea hygroscopic, e leng se o lumellang ho boloka mongobo ka katleho. Litšobotsi tsena li etsa hore glycerol e be humectant e ntle haholo, e khonang ho boloka mongobo lihlahisoa tse fapaneng.
Mekhoa ea Tlhahiso
Glycerol e ka hlahisoa ka mekhoa e 'maloa, ho kenyeletsoa le ho kopanngoa ha lik'hemik'hale le ho ntšoa ha tlhaho. Mokhoa o mong o tloaelehileng o kenyelletsa ho haelloa ha mafura le oli, e leng se hlahisang glycerol e le sehlahisoa se latelang. Mokhoa o mong ke mokhoa oa ho kopanya propylene, o kenyeletsang lits'ebetso tse kang chlorination le oxygenation. Ho feta moo, glycerol e ka hlahisoa ka saponification ea triglycerides ka sodium hydroxide, e leng se fellang ka glycerol le sesepa. Lilemong tsa morao tjena, indasteri ea biodiesel e fetohile mohloli oa bohlokoa oa glycerol, e e hlahisa e le sehlahisoa se latelang nakong ea transesterification ea oli ea meroho.
Likopo
Ho tenyetseha ha Glycerol ho bonahala ka mefuta e mengata ea ts'ebeliso ea eona liindastering tse fapaneng:
Litlolo le Tlhokomelo ea Botho: Glycerol ke motsoako oa bohlokoa lihlahisoa tse ngata tsa litlolo, ho kenyeletsoa le litlolo tse lotionang, litlolo tse tlotsang le lihlahisoa tsa tlhokomelo ea moriri. E thusa ho boloka metsi a letlalo le ho ntlafatsa sebopeho le ho ata ha metsoako. Ho ea ka Lekhotla la Lihlahisoa tsa Tlhokomelo ea Botho, glycerol e sebelisoa lihlahisoa tsa botle tse fetang 23,366, hangata ka bongata bo fihlang ho 99.4%.
Meriana: Glycerol e sebelisoa e le solvent, sweetener, le humectant litokisetsong tse fapaneng tsa meriana. Hape ke karolo ea li-syrup tsa khohlela, mafura le li-suppositories. Litšebelisong tsa bongaka, glycerol e sebelisoa ho phekola ho pipitleloa le ho fokotsa khatello ea ka hare ho boko ho bakuli ba nang le maemo a kang meningitis le stroke.
Indasteri ea Lijo: Glycerol e sebetsa e le humectant, solvent, le sweetener lihlahisoa tsa lijo. E thusa ho boloka sebopeho le mongobo linthong tse kang lipompong, lintho tse besitsoeng le ice cream. Ho feta moo, glycerol e sebelisoa tlhahisong ea lintho tse bolokang lijo le linoko.
Tšebeliso ea Liindasteri: Glycerol e sebelisoa e le setlolo le se thibelang ho hoama lits'ebetsong tsa indasteri. Hape ke karolo ea bohlokoa tlhahisong ea mefuta e itseng ea polasetiki le li-resin.
Tlhahisoleseding ea Polokeho
Glycerol ka kakaretso e tsejoa e bolokehile bakeng sa ho sebelisoa lijong, litlolong le meriana. Leha ho le joalo, e ka baka litla-morao tse bobebe tse kang hlooho e opang, ho tsekela le ho ruruha ha e nooa ka bongata. Ha e sebelisoa letlalong, glycerol e mamelloa hantle empa e ka baka bofubelu kapa ho hlohlona ho batho ba bang. Litšebelisong tsa bongaka, li-suppositories tsa glycerol le enemas li lumelloa hore li sebelisoe ntle le lengolo la ngaka ke US FDA.
Polokelo le Tsamaiso
Glycerol e lokela ho bolokoa sebakeng se pholileng, se omileng, hole le khanya ea letsatsi le mehloli ea mocheso. Ho bohlokoa ho boloka setshelo se koetsoe ka thata ho thibela ho monngoa ha mongobo le tšilafalo. Bakeng sa tšebeliso ea indasteri, glycerol hangata e pakoa ka har'a meropa kapa lijaneng tse kholo. Mekhoa e nepahetseng ea ho sebetsana le ho boloka e bohlokoa ho boloka boleng le polokeho ea sehlahisoa.
Maemo a Boleng
Glycerol e latela maemo a thata a boleng ho netefatsa bohloeki ba eona le ho loketse lits'ebetso tse fapaneng. Mekhatlo e kang United States Pharmacopeia (USP), European Pharmacopoeia (EP), le Food Chemicals Codex (FCC) e thehile litataiso tsa tlhahiso le ts'ebeliso ea glycerol. Maemo ana a kenyelletsa litlhaloso tsa litaba tsa glycerol, 'mala, monko, litaba tsa metsi, le boteng ba litšila tse kang litšepe tse boima le li-solvent tse setseng.
Ka bokhutšoanyane, glycerol ke motsoako o sebetsang ka mesebetsi e mengata o nang le mefuta e mengata ea lits'ebetso ka lebaka la thepa ea oona e ikhethang. Mekhoa ea tlhahiso ea eona, boemo ba polokeho, le ho khomarela litekanyetso tsa boleng li etsa hore e be motsoako o tšepahalang le oa bohlokoa liindastering tse fapaneng.
