2 5-Dimethoxyacetophenone (CAS# 1201-38-3)
I-2,5-Dimethoxyacetophenone iyinhlanganisela yezinto eziphilayo.
Izakhiwo zayo zihlanganisa:
- Ukubukeka: I-2,5-Dimethoxyacetophenone iyikristalu eqinile emhlophe.
- Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo ezifana notshwala, ama-ether, nama-ketone, kodwa ayincibiliki kancane emanzini.
I-2,5-Dimethoxyacetophenone isetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, njengalezi:
- I-Chemical synthesis: Ivamise ukusetshenziswa ku-organic synthesis njenge-intermediate noma i-reagent.
- Imboni yephunga: Ngenxa yokunambitheka kwayo okumnandi okuyingqayizivele, ibuye isetshenziswe kumakha kanye nokuxuba iphunga.
Izindlela eziyinhloko zokulungiselela i-2,5-dimethoxyacetophenone zimi kanje:
Ukusabela kwe-Esterification: I-2,5-dimethoxyacetophenone ikhiqizwa ngokusabela i-2,5-dimethoxyanisole nge-anhydride.
Ukusabela kwe-Ketoation: I-2,5-dimethoxyacetophenone ikhiqizwa ngokusabela i-2,5-dimethoxyanisole nge-acetic anhydride noma i-alkali metal alcohol acetate.
- Lo muthi ungase ucasule isikhumba, amehlo, nendlela yokuphefumula futhi kufanele usetshenziswe nezinto zokuvikela ezifanele njengamagilavu, izibuko kanye nesishicileli sokuphefumula.
- Gwema ukuhogela umoya noma ukuthintana namehlo nesikhumba.
- Gcina kude nemithombo yokuthungela kanye nama-oxidizing ngesikhathi sokugcina nokusebenza ukuze uvimbele ingozi yomlilo nokuqhuma.
- Lapho kulahlwa imfucuza evela kule nto, kufanele kulandelwe imithetho yendawo futhi kufanele kuthathwe izinyathelo zokwelashwa ezifanele ukunciphisa ukungcoliswa kwemvelo.
