Isingeniso

Ama-cyclic carbonate ahlanganisa ama-carbonate anamalungu amahlanu, anamalungu ayisithupha, anamalungu ayisikhombisa kanye nama-carbonate e-macrocyclic anamalungu ayisikhombisa noma ngaphezulu, phakathi kwawo i-propylene carbonate kanye ne-ethylene carbonate yiwona asetshenziswa kakhulu. I-Ethylene carbonate iyinto eluhlaza esetshenziswa kakhulu njenge-polar high-boiling point solvent kanye ne-surfactant, esetshenziswa kabanzi kumapulasitiki, ekunyatheliseni nasekudayeni, ekuhlanganisweni kwe-polymer, ekuhlukaniseni igesi kanye nase-electrochemistry.

Izakhiwo zamakhemikhali: Uketshezi olungenambala, olungenaphunga, oluvuthayo. Luxubene ne-ether, i-acetone, i-benzene, i-chloroform, i-ethyl acetate, njll., oluncibilikayo emanzini kanye ne-carbon tetrachloride

Ukusetshenziswa: Kusetshenziswa njenge-solvent enamafutha, i-solvent ejikelezayo, i-olefin kanye ne-aromatic extractant, i-carbon dioxide emunca, i-dispersant yamadayi nama-pigment ancibilikayo emanzini, njll.

Izindlela Zokukhiqiza 1. Indlela ye-Phosgene I-propylene glycol yezinto zokusetshenziswa isabela ne-phosgene ukuze ikhiqize i-hydroxyisopropyl chloroformate, bese isabela ne-sodium hydroxide ukuze ikhiqize i-propylene carbonate, bese umkhiqizo oqediwe utholakala nge-vacuum distillation. 2. Indlela yokushintshana kwe-Ester. 3. Indlela ye-Chloropropanol. 4. Indlela yokwenziwa kwe-propylene oxide ne-carbon dioxide I-Carbon dioxide ne-propylene oxide zisabela ku-150-160℃ Chemicalbook kanye ne-5MPa ukuze zikhiqize i-propylene carbonate. Umkhiqizo oqediwe utholakala nge-vacuum distillation. Izindlela ezingenhla ziye zathuthukiswa, kodwa izindlela ezintathu zokuqala zinezindleko zokukhiqiza eziphezulu kanye nekhwalithi yomkhiqizo ephansi, ngakho-ke kancane kancane zithathelwa indawo yindlela yesine. 5. Indlela yokwenziwa kwe-propylene oxidation ne-carbon dioxide. Le ndlela iyindlela yokwenziwa eyakhiwe elabhorethri eminyakeni yamuva.
