Intshayelelo
I-2,5-Dibromo-3-trimethylpyridine i-organic compound. Oku kulandelayo sintshayelelo kwezinye iipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Inkangeleko: 2,5-Dibromo-3-trimethylpyridine lulwelo olungenambala ukuya kumthubi.
- Ukunyibilika: Inokunyibilika kwizinyibilikisi ezininzi zezinto eziphilayo, ezifana ne-ethanol, i-acetone, kunye ne-dimethyl sulfoxide.
- Uzinzo: Uzinzile ekukhanyeni nasebushushu, kodwa ukubola kunokwenzeka phantsi kweemeko ezinamandla zealkaline.
Sebenzisa:
- Njenge-catalyst: i-2,5-dibromo-3-trimethylpyridine ingasetyenziselwa njenge-brominating agent ukuze i-catalyze ezinye iimpendulo zezinto eziphilayo, ezifana ne-nucleophilic substitution, i-oxidation, kunye ne-condensation.
- I-Organic synthesis: Ingasetyenziselwa njengento ephakathi kwi-synthesis ye-organic compounds, ngokukodwa kwiikhompawundi eziqukethe i-ketone okanye amaqela e-aldehyde.
- Iidayi ezithatha ifoto: Isenokusetyenziswa ekulungiseni iidayi ezibonisa ukukhanya.
Indlela:
Ngokuqhelekileyo, i-2,5-dibromo-3-trimethylpyridine inokulungiswa ngokuphendula kwe-bromination kunye ne-bromine njenge-reactant kwindlela yokusabela ye-trimethylpyridine. Iimeko zokusabela zinokumiselwa kwimeko nganye, kodwa kufuneka kuthathelwe ingqalelo ukusebenza ngokukhuselekileyo.
Ulwazi ngoKhuseleko:
- I-2,5-Dibromo-3-trimethylpyridine i-corrosion kwesikhumba kunye namehlo kwaye kufuneka igwenywe ngokudibana ngokuthe ngqo.
-Nxiba iliso elikhuselayo, iiglavu kunye nempahla ekhuselayo xa usebenzisa.
- Sebenza kwindawo engena umoya kwaye uphephe ukuphefumla umphunga wayo.
- Gwema ukunxibelelana neearhente ezinamandla ze-oxidizing, ezinokubangela ukusabela okuyingozi.
- Inkunkuma kufuneka ilahlwe ngokuhambelana nemigaqo yendawo.
