Intshayelelo
I-2,4,5-Trichloropyrimidine i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2,4,5-trichloropyrimidine:
Umgangatho:
- Ukubonakala: I-2,4,5-Trichloropyrimidine i-crystal engenambala okanye i-crystalline powder emhlophe.
- Ukunyibilika: Kuphantse kwanganyibiliki emanzini kwaye kunyibilika kwizinyibilikisi zendalo.
- Ukuzinza: I-2,4,5-trichloropyrimidine inozinzo oluhle lweekhemikhali kwaye inokugcinwa kwindawo yokushisa ixesha elide.
Sebenzisa:
- Insecticides: 2,4,5-trichloropyrimidine isetyenziswa ngokubanzi njenge-insecticide ukulawula ukhula kwizityalo zentsimi, imithi yeziqhamo kunye nemifuno.
- I-Mimics: Inokusetyenziswa kwakhona njenge-mimetic ukufunda i-pyrimidine metabolism kunye neendlela zokuphuka.
Indlela:
I-2,4,5-Trichloropyrimidine inokufumaneka ngokuphendula kwe-2,4,5-trichloropyridine nge-carbamate. Indlela ethile yokulungiselela yile ilandelayo:
1. Kwisitya sokuphendula esifanelekileyo, yongeza i-2,4,5-trichloropyridine.
2. Yongeza i-urethane kuyo.
3. Ukuphendula kwenziwa ngokwemiqathango ethile yokusabela, edla ngokufuneka ukuba iqhutywe kwiqondo lokushisa elifanelekileyo kunye nexesha lokuphendula.
Ulwazi ngoKhuseleko:
- 2,4,5-Trichloropyrimidine inetyhefu ethile kwaye kufuneka igwenywe ekudibaneni nolusu kunye nokuphefumla uthuli lwayo.
- Gqoka iiglavu ezikhuselayo, izikhuselo zobuso, kunye nezibuko xa usebenzisa i-2,4,5-trichloropyrimidine ukuqinisekisa ukuphatha ngokukhuselekileyo.
- Xa isetyenziswa, kufuneka ibekwe kwindawo engena umoya ukuze kuthintelwe ukuvela ngokugqithisileyo.
- Xa ugcina i-2,4,5-trichloropyrimidine, kufuneka ibe yodwa kwezinye iikhemikhali kwaye igweme ukutshisa kunye nokushisa okuphezulu.
