I-Dimethyl Furan-2 5-dicarboxylate cas 4282-32-0/FDME
I-FDME ingasetshenziswa njenge-organic synthesis ephakathi nendawo yemithi, ikakhulukazi esetshenziswa ocwaningweni lwaselabhorethri nezinqubo zokuthuthukiswa kanye nezinqubo zokwenziwa kwekhemikhali.
1. Ukukhiqizwa Kwepolymer: I-FDME ingasetshenziselwa ukukhiqiza i-polyester namanye ama-polymer abalulekile ekukhiqizeni amapulasitiki abolayo kanye nezinye izinto.
2. I-Chemical Intermediate: Isebenza njengendawo emaphakathi ekuhlanganisweni kwenhlanganisela yamakhemikhali ahlukahlukene, okuhlanganisa imithi kanye namakhemikhali ezolimo.
3. Imboni yephunga nephunga: Ngenxa yephunga layo elimnandi elinezithelo, ingasetshenziswa ukulungisa ama-flavour namakha.
4. Isicelo socwaningo: Ivamise ukusetshenziswa ezindaweni zocwaningo ukwenza izinto ezintsha kanye nocwaningo oluhlobene nezinsiza ezivuselelekayo kanye namakhemikhali aluhlaza.
Ipakishwe ngo-25 kg isigubhu ngasinye noma ngokusekelwe ezidingweni zamakhasimende.
I-FDME kufanele igcinwe ngaphansi kwezimo ezifanele ukuze igcine uzinzo futhi ivimbele ukucekelwa phansi. Nayi eminye imihlahlandlela yesitoreji esijwayelekile:
1. Isitsha: Gcina esitsheni esingangenisi umoya ukuze uvimbele ukungcola nokuhwamuka.
2. Izinga lokushisa: Gcina endaweni epholile, eyomile ngaphandle kwelanga eliqondile nokushisa. Ngokufanelekile, kufanele igcinwe ekamelweni lokushisa noma esiqandisini, kuye ngokuthi izincomo ezithile zomkhiqizi.
3. Igesi Engasebenzi: Uma kungenzeka, gcina ngaphansi kwegesi engasebenzi njenge-nitrogen noma i-argon ukuze unciphise ukuchayeka kumswakama nomoya, njengoba lokhu kungase kuthinte ukuzinza kwenhlanganisela.
4. Ilebula: Qinisekisa ukuthi isiqukathi sibhalwe ngokucacile igama lekhemikhali, ukugxila, kanye nanoma yiziphi izexwayiso eziyingozi.
5. Izinyathelo Zokuphepha: Landela yonke imihlahlandlela yokuphepha kanye nemithethonqubo yokuphatha nokugcina amakhemikhali, okuhlanganisa nokusetshenziswa kwezinto ezifanele zokuzivikela (i-PPE).
I-FDME CAS 4282-32-0 ngokuvamile ibhekwa njengenobuthi obuphansi, kodwa njengezinhlanganisela eziningi, ingase iveze ezinye izingozi. Nazi ezinye izinto okufanele uziqaphele mayelana nokuphepha kwayo:
1. Ukucasuka: Kungabangela ukucasuka kwesikhumba namehlo lapho uthintana. Sebenzisa izinto zokuzivikela ezifanele njengamagilavu nezibuko lapho uphatha lesi sithako.
2. Ukuhogela: Ukuhogela umhwamuko kungabangela ukucasuka kokuphefumula. Kunconywa ukungena komoya okwanele lapho usebenzisa lesi sithako.
3. Ukungenisa: Ukungeniswa kungase kube yingozi futhi kufanele kugwenywe. Hlala ulandela izinqubo zokuphepha ukuze uvimbele ukungeniswa ngephutha.
4. Umthelela Wezemvelo: Njengezinhlanganisela eziningi zezinto eziphilayo, kubalulekile ukucabangela umthelela wawo ongaba khona endaweni ezungezile. Gwema ukuyikhiphela endaweni ezungezile.
