Isingeniso esifushane
I-2-Methyl-2-pentenal yaziwa nangokuthi i-prenal noma i-hexenal. Okulandelayo yisethulo sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha kwenhlanganisela:
Ikhwalithi:
I-2-Methyl-2-pentenal iwuketshezi olungenambala olunephunga eliphunga elingavamile. Iwuketshezi olungancibiliki emanzini futhi luncibilika kuzincibilikisi eziningi eziphilayo. Ezingeni lokushisa lasekamelweni, inomfutho ophansi womhwamuko.
Sebenzisa:
I-2-Methyl-2-pentenal inohlu olubanzi lwezinhlelo zokusebenza zezimboni. Ingasetshenziswa futhi njengosizo lokucubungula irabha, i-raber antioxidant, i-resin solvent, njll.
Indlela:
Ukulungiswa kwe-2-methyl-2-pentenal kuvame ukutholwa ngokusabela kwe-isoprene ne-formaldehyde. Izinyathelo ezithile ngokuvamile zimi kanje: lapho kukhona i-catalyst efanelekile, i-isoprene ne-formaldehyde zengezwa ku-reactor ngesilinganiso esithile futhi zigcinwe ezingeni lokushisa elifanele nokucindezela. Ngemuva kokuthi ukusabela kwenziwe isikhathi esithile, i-2-methyl-2-pentenal ehlanzekile ingatholakala ngezinyathelo zenqubo ezifana nokukhipha, ukugeza amanzi, kanye nokukhishwa kwe-distillation.
Ulwazi Lokuphepha:
I-2-Methyl-2-pentenal ikhemikhali enokhahlo engacasula amehlo, isikhumba, nendlela yokuphefumula lapho ivezwa. Gqoka okokuvikela okufanele lapho usebenza futhi ugweme ukuthintana ngokuqondile ngangokunokwenzeka. Ibuye ibe uketshezi oluvuthayo futhi kufanele ivikelwe ekuthinteni izinga lokushisa eliphezulu, amalangabi avulekile kanye nama-oxidizing agents. Esimeni sokuvuza ngengozi, izinyathelo ezifanele kufanele zithathwe ngokushesha ukuze kuhlanzwe futhi kulahlwe.
