Isingeniso
(2E)-2-Butene-1,4-diol, eyaziwa nangokuthi (2E)-2-Butene-1,4-diol, iyinhlanganisela yezinto eziphilayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
(2E)-2-Butene-1,4-diol uketshezi oluphuzi olungenambala noma oluphaphathekile olunephunga elimnandi elikhethekile. Ifomula yayo yamakhemikhali yi-C4H8O2 futhi isisindo sayo samangqamuzana ngu-88.11g/mol. Inokuminyana okungu-1.057g/cm³, indawo yokubilisa engu-225-230 degrees Celsius, futhi inyibilika kuzincibilikisi ezivamile ezifana namanzi, i-ethanol ne-ether.
Sebenzisa:
(2E)-2-Butene-1,4-diol inokusetshenziswa okuningi embonini yamakhemikhali. Ingasetshenziswa njengendawo ephakathi ku-organic synthesis, ukulungiswa kwezinhlayiya zokwenziwa, izigqoko ezithuthukisiwe, odayi kanye ne-intermediate yemithi kanye nezinye izinhlanganisela. Ngaphezu kwalokho, ingasetshenziswa futhi njenge-solvent kanye ne-surfactant embonini.
Indlela Yokulungiselela:
Ukulungiswa kwe-(2E) -2-Butene-1,4-diol kungenziwa ngezindlela ezihlukahlukene. Enye indlela evamile ukuncishiswa kwe-Butenedioic acid. Lokhu kwehliswa kungase kusebenzise i-ejenti yokunciphisa njenge-hydrogen kanye ne-catalyst, noma i-reactant enciphisayo njenge-sodium hydride noma i-sulfoxide.
Ulwazi Lokuphepha:
(2E)-2-Butene-1,4-diol iyinhlanganisela ephephile uma kuqhathaniswa ngaphansi kwezimo ezijwayelekile zokusetshenziswa. Kodwa-ke, njengekhemikhali, isengadala ukulimala okuthile emzimbeni womuntu. Ukuthinta isikhumba, amehlo noma ukuhogela umhwamuko kungabangela ukucasuka nobuhlungu bamehlo. Ngakho-ke, lapho uphatha futhi usebenzisa i-(2E)-2-Butene-1,4-diol, kufanele kuthathwe izinyathelo ezifanele zokuphepha, njengokugqoka amagilavu okuvikela kanye nezinto zokuvikela amehlo, nokuqinisekisa indawo yokusebenza enomoya omuhle. Ngesikhathi esifanayo, kufanele igcinwe kude nomlilo futhi igweme ukuthintana nama-oxidants aqinile. Thola usizo lwezempilo ngokushesha uma uthinta noma udla ngephutha.
