Ka maano a thata a tikoloho le ho phahama ha tlhahiso ea maemo a holimo, n-butyl acetate e fetoha ka potlako ho tloha ho tharollo ea setso e kholo ho ea sehlahisoa se setala, se phahameng le se ikhethileng, e fetoha e 'ngoe ea likarolo tse holang ka ho fetisisa lefapheng la li-solvent tsa lik'hemik'hale.
1. Selelekela se Khutšoanyane sa n-Butyl Acetate
n-Butyl acetate (e tsejoang hape e le n-butyl ethanoate, CAS: 123-86-4) ke tharollo ea tlhaho e se nang 'mala, e bonaletsang e sa nke lehlakore e nang le monko oa litholoana. E na le foromo ea limolek'hule ea C₆H₁₂O₂, ntlha e belang ea hoo e ka bang 126°C, le thepa e tsitsitseng ea lik'hemik'hale.
Melemo ea mantlha ea n-butyl acetate:
● Ho qhibiliha ho ikhethang bakeng sa nitrocellulose, li-resin tsa acrylic, polyurethane, rabara ea tlhaho le lisebelisoa tse ling
● Sekhahla se itekanetseng sa ho feto-fetoha ha mocheso le ts'ebetso e ntle ea ho leka-lekanya, e loketse haholo bakeng sa ho roala le ho sebelisa enke
● Chefo e tlase, monko o tlase le ho bola ha lintho tse phelang, ho latela ntshetsopele ya dihlapolli tse sireletsang tikoloho.
● E tsoakana le boholo ba alcohols, ketones, ethers, aromatic hydrocarbons le dihlapolli tse ding, e na le ho tsamaellana ho matla ha formula
Maemo a mantlha a ts'ebeliso ea n-butyl acetate:
Indasteri ea ho koahela: E sebelisoa e le tharollo e ka sehloohong le motsoako bakeng sa ho koahela lehong, ho koahela tšepe le pente ea ho ntlafatsa likoloi
Indasteri ea enke: Tharollo ea bohlokoa bakeng sa enke ea offset, gravure le khatiso ea skrine, e ntlafatsang ho hlaka ha khatiso
Likhomaretsi: Li sebelisoa ho likhomaretsi tsa PU, likhomaretsi tse utloang khatello, likhomaretsi tse laminating, jj., tse ntlafatsang matla a ho kopanya le lebelo la ho omisa
Liindasteri tsa meriana le tsa monko o monate: Ho ntša meriana, ho kopanya monko o monate, hammoho le lisebelisoa tsa ho hloekisa le ho ntša oli indastering

2. Litaba tsa morao-rao tsa indasteri tsa n-Butyl Acetate
Ho tloha qalong ea 2026, liphetoho tsa bohlokoa li etsahetse 'marakeng le mafapheng a indasteri a n-butyl acetate, e leng se sutumelletsang indasteri potolohong e ncha.
1.Tlhahiso-pele ea sebaka sa acetate ea n-butyl ea maemo a holimo
Likhoebo tse 'maloa tsa lehae li atlehile ho hlahisa ka bongata n-butyl acetate ea boleng ba elektroniki le n-butyl acetate ea boleng ba meriana ka bohloeki bo fetang 99.95%. Matšoao a li-ion tsa tšepe le mongobo a fihlile maemong a tsoetseng pele a machaba, a roba ho itšetleha ha nako e telele ka thepa e tsoang kantle ho naha. N-butyl acetate e hloekileng haholo e kene liketane tsa phepelo ea matla a macha, tlhoekiso ea semiconductor le enke ea liphutheloana tse phahameng.
2. Mekhoa e tala e potlakisa ho nkeloa sebaka ha mekhoa ea setso
Mekhoa e mecha ea ho hlahisa n-butyl acetate ka ho sebelisa catalysis ea solid acid le continuous reactive distillation e ntse e tuma ka potlako. Ha e bapisoa le mokhoa oa setso oa sulfuric acid, litšila tse hlahisoang ke asiti li fokotseha ka ho feta 90%, 'me tšebeliso ea matla e fokotseha ka 25%–30%. Bahlahisi ba ka sehloohong ba n-butyl acetate ba phethetse ntlafatso ea tekheniki ho fihlela tlhahiso e tala le e nang le khabone e tlase.
3. Phepelo, tlhoko le matla a theko a n-butyl acetate
Ka Hlakola 2026, e anngoeng ke ho qalisoa hape ha mosebetsi ka mor'a Mokete oa Selemo, 'maraka oa n-butyl acetate o ile oa lula o tsitsitse ka kakaretso, ka litheko tse kholo tsa litšebelisano Chaena Bochabela li tloha ho 5,500 ho isa ho 5,800 RMB/ton. Ka ho hlaphoheloa butle-butle ha liindasteri tsa ho roala, ho paka le ho khomarela, tlhoko le litheko tsa n-butyl acetate li lebelletsoe ho kena mocha oa ho khutlela morao ho qala ka Hlakubele.

3. Mekhoa ea Indasteri ea n-Butyl Acetate
Lilemong tse 3-5 tse tlang, indasteri ea n-butyl acetate e tla nts'etsapele ho potoloha mela e meraro e meholo: ho lema, nts'etsopele ea maemo a holimo le ho tsepamisa mohopolo.
3.1 Maano a tikoloho a susumetsa n-butyl acetate ho nkela ditharollo tse nang le VOC e ngata sebaka
Ka melao e thata ea puso ea VOC ea lehae le molao oa EU REACH, litharollo tse chefo haholo le tse nkhang hampe li ntse li ikhula butle-butle 'marakeng. Ka lebaka la chefo ea eona e tlase, ho senyeha ha eona le mesi e kotsi tikolohong, n-butyl acetate e fetohile mokhoa o khethiloeng, ka ho kenella ho ntseng ho eketseha ka har'a liphutheloana tsa lijo, lihlahisoa tsa bana, liphahlo tsa likoloi le masimo a mang.
3.2 Ditshebediso tsa maemo a hodimo di fetoha enjene e kgolo ya kgolo bakeng sa n-butyl acetate
Kholo ea n-butyl acetate ea sehlopha sa solvent e ntse e fokotseha, ha tlhoko ea n-butyl acetate ea sehlopha sa elektroniki, n-butyl acetate ea sehlopha sa meriana le n-butyl acetate ea sehlopha sa photovoltaic e ntse e hola ka holimo ho 15% ka selemo. N-butyl acetate ea sehlopha se khethehileng e nang le bohloeki bo phahameng, litšila tse tlase le mongobo o tlase e tla ba motheo oa phaello ea lik'hamphani le tlholisano.
3.3 Ho eketseha ha tlhokeho ea indasteri, likhoebo tse etellang pele tse busang 'maraka oa n-butyl acetate
Diyuniti tse nyane, tse siilweng ke nako le tse silafatsang haholo tsa n-butyl acetate di ntse di tswa mmarakeng ka mehla. Dikgwebo tse kgolo tse kopaneng di ntse di atolosa karolo ya tsona ya mmaraka ka lebaka la kopanyo ya thepa e tala, melemo ya ditjeo le ho latela melao ya tikoloho. Mmaraka wa nakong e tlang wa n-butyl acetate o tla ba le mohlala wa "ho tsepamisa maikutlo hodimo le boetapele dikarolong tse hodimo".
3.4 N-butyl acetate e thehiloeng ho bio e bula pina e ncha
N-butyl acetate e thehiloeng ho bio, e hlahisoang ho tsoa ho n-butanol e belisitsoeng ho bio, e kene mehatong ea liteko le ea indasteri, ka mesi ea khabone e ka tlase ho 40% ho feta tsela ea petrochemical. Setifikeiti se setala le ho romelloa kantle ho naha ka khabone e tlase li tla ntlafatsa tlholisano ea n-butyl acetate e thehiloeng ho bio nakong e tlang.
Qetello
n-butyl acetate e ka bonahala e le tharollo e tloaelehileng ea indasteri, leha ho le joalo ke thepa ea motheo ea bohlokoa bakeng sa ho roala, enke, likhomaretsi le tlhahiso ea maemo a holimo. Ka lebaka la ntlafatso ea tikoloho le phetoho ea indasteri, n-butyl acetate e fetoha ho tloha "ka bongata bo boholo le ka theko e tlase" ho ea "boleng bo holimo le ba boleng bo holimo". Likhoebo tse fumanang melemo lits'ebetsong tse tala, lihlahisoa tsa maemo a holimo le botsitso ba ketane ea phepelo li tla etella pele potolohong e latelang ea kholo ea n-butyl acetate.
