N-Propanol: Thepa ea Bohlokoa ea Lik'hemik'hale tsa Lintho tse Tala
Masimo a Maholo a Kopo
Indastering ea lik'hemik'hale, n-propanol ke karolo ea bohlokoa ea motsoako oa lintho tse phelang. E ka sebelisoa ho hlahisa metsoako e fapaneng, joalo ka acrylic acid, metsoako ea acrylate, propyl acetate, propyl urea, le bromopropane. Metsoako ena e sebelisoa haholo tlhahisong ea polasetiki, liphahlo, likhomaretsi, monko o monate le lintho tse ling tse tlatsetsang lijong. Mohlala, acrylic acid le li-ester tsa eona ke thepa ea bohlokoa bakeng sa ho hlahisa liphahlo le likhomaretsi tse sebetsang hantle; propyl acetate e sebelisoa hangata indastering ea motsoako oa lintho tse phelang le li-solvent e le tharollo e belang haholo. Ho feta moo, n-propanol e ka omisoa ho hlahisa propylene, e leng thepa ea bohlokoa bakeng sa tlhahiso ea polasetiki ea polypropylene.
Indastering ea meriana, n-propanol e sebelisoa ho hlahisa mefuta e fapaneng ea meriana e mahareng. Mohlala, probenecid, e sebelisetsoang ho phekola gout, e na le n-propanol e le karolo ea bohlokoa tlhahisong ea eona; valproate sodium, moriana o thibelang lefu la sethoathoa, le oona o itšetlehile ka n-propanol ts'ebetsong ea tlhahiso ea oona. Ho feta moo, n-propanol e sebelisoa e le tharollo bakeng sa meriana, haholo-holo tlhahisong ea liente le lino tse nooang. E ka qhala likarolo tse ngata tsa meriana e sa qhibiliheng hantle, e leng se ntlafatsang botsitso le ho fumaneha ha meriana.
Litlolong le lihlahisoa tsa tlhokomelo ea botho, n-propanol e sebelisoa hangata e le tharollo. E ka qhala metsoako e fapaneng e sebetsang, monko o monate le mebala, e thusa likarolo tsena ho hasana hamolemo lihlahisoa. Mohlala, tlhahisong ea monko o monate, n-propanol e ka sebelisoa e le tharollo ho aba likarolo tsa monko ka ho lekana, ho ntlafatsa nako e telele le botsitso ba monko o monate. Ho feta moo, n-propanol e ka sebelisoa e le sesebelisoa sa ho bolaea likokoana-hloko bakeng sa ho hloekisa le ho bolaea likokoana-hloko lipetlele, lilaboratori le malapeng. E na le litlamorao tse ntle tsa ho bolaea baktheria, e ka bolaea libaktheria le livaerase ka katleho, 'me e na le ho feto-fetoha ho itekanetseng, e sa siee masalla kamora tšebeliso.
Moeding wa ho hlwekisa le masimong a mafura, n-propanol e sebediswa ho hlahisa maro a brake. E na le ho qhibiliha le ho tlotsa ho hotle, e fokotsa kgohlano ka katleho ditsamaisong tsa brake le ho ntlafatsa tshebetso ya brake. Ho feta moo, n-propanol e ka sebediswa e le sehlomathiso sa mafura mafurang a kopantsweng ho ntlafatsa bokgoni ba ho tuka. Mohlala, ho eketsa n-propanol e nyane peteroleng ho ka ntlafatsa bokgoni ba yona ba ho thibela ho kgokgothoa le tshebetso ya ho tuka ha ka nako e ts'oanang ho fokotsa mosi o tswang mosi.
Litšobotsi tsa lik'hemik'hale tsa n-propanol li etsa hore e be sehlahisoa sa lik'hemik'hale se feto-fetohang. E na le ho qhibiliha ho hotle 'me e ka kopanngoa le metsi, li-alcohol, li-ether le li-solvents tse ling tse ngata. Ka ntlha ea ho belisa ea 97.2°C le ntlha ea ho qhibiliha ea -127°C, n-propanol e na le chefo e fokolang haholo empa e ka baka ho teneha mahlong, tseleng ea ho hema le letlalong ka bongata bo phahameng. Ka hona, nakong ea tšebeliso le polokelo, lisebelisoa tse loketseng tsa tšireletso li lokela ho aparoa ho qoba ho kopana le letlalo le mahlo, 'me moea o kenang hantle o lokela ho bolokoa.
