2-Pentene-1 5-diol (E)- (CAS# 25073-26-1)
Isingeniso
(E)-Pent-2-ene-1, 5-diol, eyaziwa nangokuthi 2-Pentene-1,5-diol, iyinhlanganisela yezinto eziphilayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:
Imvelo:
(E)-Pent-2-ene-1, 5-diol uketshezi olungenambala ukuya kokuphuzi olukhanyayo olunephunga elimnandi. Ifomula yayo yamangqamuzana ithi C5H10O2 futhi isisindo sayo samangqamuzana ngu-102.13g/mol. Ayincibiliki emanzini, kodwa iyancibilika otshwaleni nasezincibilikisini ze-ether.
Sebenzisa:
(E)-Pent-2-ene-1, 5-diol inezinhlobonhlobo zokusetshenziswa embonini yamakhemikhali. Njengengxenye ephakathi ku-organic synthesis, ivame ukusetshenziswa ekuhlanganiseni izinhlanganisela ezihlukahlukene, njengama-polyester resins nama-polyurethanes. Ngaphezu kwalokho, ingasetshenziswa njenge-surfactant, i-plasticizer, i-flame retardant, nokunye okunjalo.
Indlela:
(E)-pent-2-ene-1, 5-diol inezindlela eziningi zokulungiselela. Okulandelayo kungenye yezindlela zokwenziwa ezivame ukusetshenziswa: kusukela ku-(E) kusukela ku-pent-2-ene-1, 4-dialdehyde, (E)-pent-2-ene-1, 5-diol ingatholakala ngokunciphisa .
Ulwazi Lokuphepha:
(E)-Pent-2-ene-1, 5-diol inobuthi obuphansi ngaphansi kwezimo zokusetshenziswa ezijwayelekile. Nokho, ukuthintana ngqo nesikhumba namehlo kungase kubangele ukucasuka. Gqoka izinto zokuzivikela ezifanele ezifana namagilavu nezibuko lapho uphatha inhlanganisela. Ngaphezu kwalokho, kufanele igcinwe esitsheni esivaliwe, kude nomlilo kanye nama-oxidizing agents. Uma kukhona ukuvuza ngengozi, kufanele kuhlanzwe ngokushesha futhi kusingathwe ngendlela efanele. Lapho usebenzisa le nhlanganisela, izinqubo zokuphepha ezifanele kufanele zibhekwe ngokuqinile. Ukuze uqinisekise ukuphepha, sicela ubhekisele efomini ledatha ethile yezokuphepha noma uthintane nenhlangano efanele yochwepheshe.
