I-DMC igqame ngobuthi bayo obuphansi, ukubola kwemvelo, amandla e-solvency aphezulu, i-viscosity ephansi, kanye nokungaguquki kwe-dielectric ephezulu, ikubeka njengesinyibilikisi 'esiluhlaza' esikhethwayo kanye ne-reagent.

Izicelo Eziyinhloko Nokusetshenziswa

• Ama-Electrolyte Ebhethri Le-Lithium-Ion : I-co-solvent ebalulekile kuma-electrolyte ebhethri ye-Li-ion ngenxa yokuzinza okuhle kakhulu kwe-electrochemical, i-viscosity ephansi, i-dielectric constant, kanye nekhono lokuthuthukisa ukuqhutshwa kwe-ionic, ukusebenza kahle kokushaja, nokusebenza okushisayo kuma-EV, izinto zikagesi zabathengi, nezinhlelo zokugcina amandla.

  
  

• Ukukhiqizwa Kwe-Polycarbonate : Umzila ongukhiye ongeyona i-phosgene omaphakathi wokwenziwa kwe-polycarbonate nge-transesterification nge-bisphenol A, evumela ukwenziwa kwepulasitiki eluhlaza.

  
  

• I-Solvent in Coatings, Paints, Adhesive, and Inks : Ukuhwamuka okusheshayo, i-VOC-exemppt (ezifundeni eziningi) i-solvent ye-polar ethatha indawo yezincibilikisi zendabuko njenge-MEK, i-acetone, noma i-glycol ethers; inikeza i-solvency enhle kakhulu, ukomisa okusheshayo, kanye nokukhishwa kwekhabhoni encishisiwe.

  
  

• I-Pharmaceutical and Agrochemical Synthesis : I-ejenti ye-methylating eluhlaza kanye ne-carbonylating yama-API, ama-intermediates, ama-carbamates, nezibulala-zinambuzane; okunye okunobuthi obuphansi ekwakhiweni kwezidakamizwa kanye ne-organic synthesis.

  
  

• Izithasiselo Zezibaseli Namandla Ahlanzekile : Ithuthukisa okuqukethwe komoyampilo kanye nenombolo ye-octane kumafutha; isetshenziswa ekukhiqizweni kwe-biodiesel nanjengesengezo se-eco-friendly.

  
  

• Okunye Ukusetshenziswa : I-Reagent ku-organic synthesis (i-methoxylation, i-carbonylation), i-ejenti yokuhlanza/yokukhipha amafutha, izinto zokuthambisa, ukukhiqizwa kwe-polyurethane, nanjengesilondolozi noma isincibilikisi ezisetshenziswa ezikhethekile.

  
  

Kungani Khetha I-Dimethyl Carbonate Yethu Yekhwalithi Ephezulu?

I-DMC yethu ihlinzekwa ngamamaki amaningi—izimboni (>99.0%), ezemithi (>99.5%), nebhethri/electronic (>99.9% enokungcola okuphansi kakhulu)—ukuze ihlangabezane nezidingo eziqinile zokuhlanzeka, ukulawula umswakama, nemikhawulo ye-ion yensimbi. Ukuqinisekiswa kwekhwalithi eqinile kuqinisekisa ukungcola okuncane kwemiphumela ekwazi ukukhiqizwa kabusha ekwakhiweni kwebhethri okubucayi, izinqubo zemithi, nezingubo ezisebenza kahle kakhulu. Ipakishwe ngaphansi kwezimo ze-inert ukuze kugcinwe ukuzinza nokuvimbela ukungena komswakama.

Ulwazi Lokuphepha Nokuphatha

I-Dimethyl carbonate ihlukaniswa njengoketshezi oluvutha kakhulu (Isigaba 2) ngaphansi kwe-GHS. Izihwamuko zisinda kunomoya futhi zingakha izingxube eziqhumayo. Ingase ibangele ukucasuka kwamehlo/isikhumba futhi ibe yingozi uma ihogelwe noma igwinywe inani elikhulu. Bamba ezindaweni ezinomoya omuhle noma izivalo zomusi ezinesisekelo ukuze uvimbele izinhlansi ezimile. Sebenzisa okokuvikela ukuqhuma, gqoka i-PPE efanele (izingubo ezimelana namalangabi, amagilavu, izibuko), futhi ugweme imithombo yokuntula. Gcina ezitsheni ezivalwe ngokuqinile endaweni epholile, eyomile kude nama-oxidizer nezisekelo eziqinile. Bheka i-SDS yakamuva ukuze uthole ubungozi obugcwele, usizo lokuqala, nolwazi lokulahla.

Imibuzo Evame Ukubuzwa (FAQs)

Ithini inombolo ye-CAS ye-dimethyl carbonate?

Inombolo ye-CAS ithi 616-38-6.

Yini eyenza i-dimethyl carbonate ibe ikhemikhali 'eluhlaza'?

Inobuthi obuphansi, i-biodegradable, i-VOC-ekhishiwe ezindaweni eziningi, futhi ikhiqizwa ngezindlela ezingezona ze-phosgene, esebenza njengenye indlela ephephile ye-dimethyl sulfate, i-phosgene, noma i-methyl halides.

Kungani i-DMC isetshenziswa kabanzi kuma-electrolyte ebhethri ye-lithium-ion?

Ukungaguquguquki kwayo okuphezulu kwe-dielectric, i-viscosity ephansi, kanye nokuzinza kwe-electrochemical kuthuthukisa ukuguquguquka kwe-ionic, ukusebenza kahle kwebhethri, nempilo yomjikelezo uma kuqhathaniswa nezinye izincibilikisi ze-carbonate.

Ingabe i-dimethyl carbonate ilungele ukusetshenziswa kwemithi?

Yebo, i-DMC yezinga lezemithi ihlangabezana nezindinganiso zokuhlanzeka okuphezulu futhi isetshenziswa njenge-ejenti ye-methylating/carbonlating ekuhlanganiseni kwe-API enezingozi ezincishisiwe zobuthi.

I-DMC iqhathaniswa kanjani nezinye izincibilikisi njenge-acetone noma i-MEK?

I-DMC inikeza i-solvency efanayo noma engcono, ukuhwamuka okusheshayo, ubuthi obuphansi, futhi ngokuvamile isimo sokukhululwa nge-VOC, okuyenza ibe indawo ekhethwayo yopende, ama-coatings, kanye nezakhiwo zokuhlanza.

Ingabe i-dimethyl carbonate iyavutha?

Yebo, ivutha kakhulu nge-flash point ephansi (~18 °C); phatha ngezinyathelo eziqinile zokuvimbela umlilo.

Ukuze uthole izingcaphuno, izitifiketi zokuhlaziya, amasampula, amamaki ngokwezifiso, noma ukunikezwa ngobuningi kwe-dimethyl carbonate CAS 616-38-6, sicela uthinte ithimba lethu.
