Mu gawo la organic chemistry, 2-Methoxy-2-methylpropane, amadziwikanso ndi dzina lodziwika bwino la tert-butyl methyl ether (Tsamba la tbme), ndi yosunthika komanso yogwiritsidwa ntchito kwambiri. Nkhaniyi ikufuna kupereka kusanthula kwathunthu kwa 2-methoxy-2-methylpropane, kuyang'ana kapangidwe kake ka maselo, katundu wathupi, mankhwala katundu, ndi ntchito zosiyanasiyana m'mafakitale osiyanasiyana.
Kapangidwe ka Maselo:
2-Methoxy-2-Methylpone imakhala ndi atomu yapakati ya kaboni yolumikizidwa kumagulu atatu a methyl ndi gulu limodzi la methoxy (-Och3). Mapangidwe a maselo a pawiriwa ndi C5H12O, ndipo dongosolo lake likhoza kuimiridwa motere:Koperani

Zakuthupi:
- Maonekedwe: Madzi opanda colorless firiji
- Kununkhira: Wofatsa, fungo la ethereal
- Kulemera kwa maselo: 88.15 g/mol
- Malo osungunuka: -108.6 °C (-167.5 °F)
- Malo otentha: 55.2 °C (131.4 °F)
- Kuchulukana: 0.74 g/ml ku 25 °C (77 °F)
- Kuthamanga kwa Vapor: 100 mmHg ku 20 °C (68 °F)
- Kusungunuka: Kusakaniza ndi madzi, mowa, ndi okhazikika ambiri
Mankhwala:
- Ether Functional Group: Kukhalapo kwa gulu logwira ntchito la ether (-O-) mu 2-methoxy-2-methylpropane imapangitsa kuti ikhale yokhazikika.
- Reactivity: TBME nthawi zambiri imakhala yosagwira ntchito nthawi zonse koma imatha kukumana ndi zochitika zina monga okosijeni, hydrolysis, ndi acid-catalyzed cleavage.
- Kunyezimila: 2-Methoxy-2-methylpropane ndi yoyaka kwambiri ndipo imakhala ndi malo otsika, kuzipangitsa kukhala ngozi yoyaka moto.
Mapulogalamu:
- Zowonjezera mafuta:
- TBME imagwiritsidwa ntchito makamaka ngati oxygenate mu petulo, kumathandiza kupititsa patsogolo mphamvu ya mafuta ndi kuchepetsa mpweya.
- Zosungunulira:
- Chifukwa cha zinthu zake zabwino kwambiri za solvency, 2-methoxy-2-methylpropane amagwiritsidwa ntchito ngati zosungunulira m'mafakitale osiyanasiyana, kuphatikizapo zojambula, zokutira, ndi zomatira.
- Mankhwala apakati:
- TBME imagwira ntchito ngati chinsinsi chapakatikati pakuphatikizika kwazinthu zina, monga isobutylene ndi methacrylic acid.
- Wothandizira Pharmaceutical:
- M'makampani opanga mankhwala, TBME imagwiritsidwa ntchito ngati zosungunulira ndi zowonjezera zowonjezera m'magulu ena amankhwala.
- Aerosol Propellant:
- 2-Methoxy-2-methylpropane amagwiritsidwa ntchito ngati propellant mu mankhwala aerosol, monga zopaka tsitsi ndi mankhwala ophera tizilombo.

Mankhwala:
- Reactivity: Onse IBME ndi TBME sagwira ntchito nthawi zonse koma amatha kuchita zinthu zina monga okosijeni., hydrolysis, ndi acid-catalyzed cleavage.
- Ether Functional Group: Kukhalapo kwa gulu logwira ntchito la ether (-O-) m'magulu onsewa amawapangitsa kukhala okhazikika.
Mapulogalamu:
- Mafuta Owonjezera:
- IBME ndi TBME onse amagwiritsidwa ntchito ngati oxygenates mu mafuta, kumathandiza kupititsa patsogolo mphamvu ya mafuta ndi kuchepetsa mpweya.
- Zosungunulira:
- IBME ndi TBME amagwiritsidwa ntchito kwambiri ngati zosungunulira m'mafakitale osiyanasiyana, kuphatikizapo zojambula, zokutira, ndi zomatira.
- Chemical Intermediates:
Mankhwala onsewa amagwira ntchito ngati zopatsirana zazikulu pakuphatikizika kwazinthu zina za organic.
