Global - Premier Isopropyl Alcohol: Nkatsakanyo wa Organic lowu nga na swiyenge swo tala
Swihlawulekisi swa Xiviri na Tikhemikhali
Ku languteka na Ku nun’hwela: . I mati lama nga riki na muhlovo lama vonakaka lama nga ni nun’hwelo lowu fanaka ni wa ethanol.
Ku n’oka: . Yinga hlanganisiwa na mati, ethanol, ether, acetone, na swin’wana swa organic solvents.
Swihlawulekisi Swin’wana: Nhlayo ya yona ya molar i 60.10 g/mol, density i 0.786 g/mL (eka 25°C), melting point i - 89.5°C, naswona ku vila i 82.3°C. Nhlayo ya ku vonakala ka yona i 11.7°C.
Tindhawu ta Swikombelo
Xigwitsirisi: . Yitirha tani hi solvent ya kahle swinene eka shellac, nitrocellulose, alkaloids, rubber, oils, etc. Yitlhela yitirhisiwa eka ku endliwa ka swidlaya switsotswana na switirhisiwa swo basisa nghilazi. Ku engetela kwalano, yinga tirha tani hi extractant ya mafurha ya cottonseed na swipayisisi.
Switirhisiwa swo ka swi nga tirhisiwanga eka Vumaki bya Tikhemikhali ta Organic: Hiku tirhisa ti reactions tohambana hambana, yinga humesa switirhisiwa swohambana hambana swa ti khemikhali swofana na isopropylamine, methyl isobutyl ketone, methyl isobutyl carbinol, etc. Switirhisiwa leswi switirhisiwa ngopfu eka ti indasitiri tofana na mirhi, swidlaya switsotswana, swifunengeto, na ti inks.
Nsimu ya Vumaki bya Mirhi: . I raw material yo endla mirhi yofana na Propranolol, Rifampicin, Pindolol, Diisopropylamine Dichloroacetate, etc. Yinga tirhisiwa ku humesa ti vitamins xikan’we naku basisa ti capsules ta mirhi. Hakanyingi yitirhisiwa tani hi murhi wo dlaya switsongwatsongwana eka nhlonge, swirho swa xitekela, na switirhisiwa swa vutshunguri, naswona yinga tlhela yitirhisiwa eka ku hlayisa swikombiso swa biological.
Nsimu ya Vumaki bya swa Elektroniki: High - purity isopropyl alcohol yitirhisiwa tani hi xitirhisiwa xo basisa xikan’we na etchant hinkarhi wa vuhumelerisi bya swiphemu swa semiconductor xikan’we naku hlengeletiwa naku lulamisiwa ka swirhendzevutani leswi hlanganisiweke swa xikalo lexikulu swinene. Yinga tlhela yitirhisiwa tani hi metal degreasing cleaning agent.
Nsimu ya Mimovha: Tanihi xiengeteri xa mafurha, swinga engetela nhlayo ya octane ya petirolo, leswi antswisaka khwalithi ya petirolo. Yinga tlhela yitirhisiwa tani hi xibasisi xa nghilazi ya timovha, deicer eka swivoni swa movha, na anti - fogging agent eka aerosol - type windshields.
Maendlelo yo Lunghiselela
Ku nghenisiwa ka mati ya Propylene: Sweswi, direct hydration ya propylene i ndlela leyikulu. Ehansi ka ntirho wa catalyst, propylene yi endla reaction hiku kongoma na mati hiku tirhisa addition reaction kuva yi humesa isopropyl alcohol. Kuya hi xiyimo xa phase xa ti reactants, yinga avanyisiwa hi ndlela ya gas phase, ndlela ya gas - liquid mixed phase, na ndlela ya liquid phase.
Ku endliwa ka hayidirojeni ya Acetone: Ehansi ka ntirho wa catalyst, acetone yi hungutiwile kuva isopropyl alcohol eka xibakabaka xa hydrogen. Ndlela leyi yina mahiselo yale hansi swinene ya reaction, ntshikelelo wa ntolovelo, ku tirhisiwa ka eneji yale hansi, ku khuluka ka maendlelo yo olova, xikan’we na corrosion leyintsongo eka switirhisiwa.
Ku endliwa ka hayidirojeni ya Isopropyl Acetate: Ehansi ka ntirho wa catalyst, isopropyl acetate yi hydrogenated kuva yi humesa isopropyl alcohol na ethanol hi nkarhi wun’we. Hambiswiritano, kuna switirhisiwa swotala swa by - products, naswona ku hambanyisa ethanol na isopropyl alcohol swa tika, hikokwalaho aswi tirhisiwanga ngopfu.
Switsundzuxo
Mpfumawulo wa byala bya isopropyl wu hlundzukisa mahlo ni nhlonge naswona ku hefemula swi nga va ni chefu. Yi wela eka xitsongwatsongwana xa Class 3 xa carcinogen. Loko vanhu va hefemula mpimo wo hambana-hambana wa byala bya isopropyl, va ta va ni swiendlo swo hambana-hambana. Xikombiso, eka 400 ppm, swita vanga ku hlundzuka lokuntsongo eka mahlo, nhlonge, na nkolo, naswona eka 20000 ppm, swita hatla swi veka vutomi kumbe rihanyo ekhombyeni.
Byala bya isopropyl byi nga pfurha. Mpfula ya yona yi nga endla nkatsakanyo lowu pfurhaka ni moya. Yinga vanga ku hisa naku buluka loko yi hlangana na malangavi lawa ya pfulekeke na kuhisa lokukulu. Yifanele ku hlayisiwa eka ndzhawu yo hlayisela swilo yo kufumela naku nghenisiwa moya, ekule na swihlovo swa ndzilo na swihlovo swo hisa, yi sirheleriwa eka ku vonakala ka dyambu hiku kongoma, naswona xigwitsirisi xifanele ku hlayisiwa xi pfaleriwile. Yifanele ku hlayisiwa hiku hambana na ti oxidants.
