Icandelo lesiBini Ukusetyenziswa kweDimethyl carbonate (DMC)

1. Ipeyinti, ukwambathisa kunye neshishini lokuncamathelisa

Ngenxa yokunyibilika kwayo okugqwesileyo, ukunyibilika okuncinci kunye noluhlu lwamanqaku abilayo, ukuxinezeleka komhlaba okukhulu, i-viscosity encinci, kunye ne-dielectric constant, i-dimethyl carbonate inokutshintsha i-toluene eyityhefu kunye nemveliso ye-xylene kwaye isetyenziswa ngokubanzi kwiipeyinti eziphezulu, iingubo, izinto zokuncamathelisa, njl. Iglu kunye namanye amashishini.

2. Ishishini lePolycarbonate

I-Dimethyl carbonate isetyenziswa ngokubanzi kwiintlobo ezahlukeneyo ze-organic reactions kwaye ngokuthe ngcembe ithatha indawo ye-phosgene kwimveliso ye-polycarbonate kunye ne-isocyanate, ene-gap enkulu yemarike. I-Polycarbonate yinto eqhelekileyo yemihla ngemihla kunye nokumelana nempembelelo ebalaseleyo. Yimveliso kuphela enokucaca kakuhle phakathi kweeplastiki ezinkulu ezintlanu zobunjineli. Ikwayeyona ikhula ngokukhawuleza iplastiki yobunjineli ngokubanzi kwiminyaka yakutshanje. Ngoku isetyenziswa ngokubanzi kwiimoto, i-elektroniki kunye nombane, ukwakhiwa, izixhobo zeofisi, ukupakishwa, izixhobo zemidlalo, ukhathalelo lwezonyango kunye namanye amacandelo. Ngokuqhubekayo ukujula kophando lokuguqulwa, ikhula ngokukhawuleza kwiinkalo zobuchwepheshe obuphezulu ezifana ne-aerospace, iikhomputha, iidiski ezibonakalayo kunye nokunye.

3. I-electrolyte yebhetri ye-lithium-ion

Ngokuphunyezwa ngokuqhubekayo kwesicwangciso selizwe elitsha loshishino lwamandla, i-mopeds yombane kunye nemarike yeemoto zombane, phantsi kwesikhokelo sesicwangciso selizwe elitsha lamandla, i-Dimethyl carbonate iba yenye yamashishini anethemba elikhulu lemarike kwilizwe lam kwixesha elizayo. Ngokuhambelanayo, imveliso kunye nemfuno yoshishino lwebhetri ye-lithium nayo yonyukile. Ukukhula ngokukhawuleza. Njengenye yezixhobo eziphambili ze-electrolyte yebhetri, iimveliso ze-carbonate ziya kuba nokukhula ngokukhawuleza kwimfuno kwintsimi yeebhetri ze-lithium.

4. Izongezo zeoyile

Ngenxa yomxholo we-oksijeni ophezulu (i-oksijeni i-53%, ngokuphindwe kathathu i-MTBE) kunye noxinzelelo lomphunga olufanelekileyo, ukuxhathisa kwamanzi kunye nokuxuba ukusabalalisa i-coefficient, i-Dimethyl carbonate ingasetyenziselwa njengesongezo esifanelekileyo se-petroli / i-diesel ukukhuthaza ukutsha kunye nokwandisa i-octane. ixabiso, ukunciphisa ukukhutshwa kwekhabhoni, kwaye ngexesha elifanayo kuphuculwe ukusebenza kwe-anti-knock ye-petroli / i-diesel.

5. Ishishini lamachiza

Ishishini lamayeza okwangoku liyindawo ebalulekileyo yokusetyenziswa kwe-dimethyl carbonate kwilizwe lam. Kwiyeza, i-dimethyl carbonate isetyenziswa kakhulu njenge-methylating agent ukuba ithathe indawo ye-dimethyl sulfate enetyhefu kakhulu, kwaye isetyenziselwa ukudibanisa iziyobisi ezichasayo, i-antipyretics kunye ne-analgesics. amayeza, iivithamini, kunye namayeza enkqubo yemithambo-luvo.

6. Izibulali-zinambuzane

ilizwe lam livelisa kakhulu izibulali-zinambuzane. Njengoko isantya sohlengahlengiso lwesakhiwo soshishino lwelizwe lam lokubulala izitshabalalisi sikhula, iimfuno zelizwe zokhuseleko lwezitshabalalisi ziya kuba ngqongqo ngakumbi. Izitshabalalisi zemveli ezinetyhefu kakhulu ziya kutshintshwa ngokuthe ngcembe zitshintshwe ngezibulali-zinambuzane ezingenatyhefu nezinetyhefu esezantsi. Ngoko ke, njengohlaza Ukusetyenziswa kwemveliso ye-dimethyl carbonate ephakathi kwintsimi yemveliso ye-pesticide iya kuba nethemba lophuhliso olubanzi.

7. ADC resin

I-Allyl diglycol carbonate (ADC) ineempawu ezintle kakhulu ze-optical, ukumelana nokugqoka, ukuxhathisa ibhaktheriya, kunye nobunzima obulula. Yiresin ye-thermosetting. Ingathatha indawo yeglasi kwaye isetyenziswe njengeelensi zokubukela kunye nezixhobo ze-optoelectronic. Yayisenziwa ekuqaleni kwi-propylene alcohol, i-diethyl glycol kunye ne-phosgene. Kule mihla, ishishini ngokubanzi lisebenzisa i-DMC ukuthatha indawo ye-phosgene. Ngenxa yokuba i-DMC inetyhefu ephantsi kwaye ayinamhlwa, inciphisa iimfuno zobugcisa kwimveliso yezixhobo, ulawulo lokusebenza kunye nonyango lwenkunkuma. Okubaluleke ngakumbi, iimveliso ezikumgangatho ophezulu zinokuveliswa ngokulula. Ke ngoko, imimandla emitsha efana nokusetyenziswa njengezinto ezichanekileyo ze-optoelectronic ziyavulwa.
