2 3-DIBROMO-5-CHLORO PYRIDINE (CAS# 137628-17-2) mawu oyamba
2,3-dibromo-5-chloropyridine ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera, ndi chidziwitso cha chitetezo cha pawiri:
chilengedwe:
-Maonekedwe: 2,3-dibromo-5-chloropyridine ndi olimba wopanda mtundu wachikasu.
-Kusungunuka: Imakhala ndi kusungunuka kwakukulu mu zosungunulira za organic koma kusungunuka kochepa m'madzi.
Cholinga:
2,3-dibromo-5-chloropyridine ali osiyanasiyana ntchito mu kaphatikizidwe organic, makamaka ntchito m'madera otsatirawa:
-Monga photosensitizer, itha kugwiritsidwa ntchito m'minda monga kusindikiza ndi kupanga zithunzi.
Njira yopanga:
Njira yokonzekera 2,3-dibromo-5-chloropyridine imatha kuchitidwa motere:
Pazifukwa zoyenera, gwiritsani ntchito 2,3-dibromopyridine ndi phosphorous pentachloride kupanga 2,3-dibromo-5-chloropyridine pentachloride.
Kenako pentachloride ndi sodium hydroxide kapena njira zina zamchere kuti mupeze 2,3-dibromo-5-chloropyridine.
Zambiri zachitetezo:
-Kugwiritsiridwa ntchito ndi ntchito ya 2,3-dibromo-5-chloropyridine iyenera kuchitidwa m'dera lokhala ndi mpweya wabwino kuti lisawonongeke nthawi yayitali ndi fungo lake kapena fumbi.
-Panthawi yogwira ntchitoyo, zida zoyenera zodzitetezera ziyenera kuvalidwa, kuphatikiza magolovesi oteteza mankhwala, magalasi, ndi zovala zodzitchinjiriza.
-2,3-dibromo-5-chloropyridine ndi organic bromides ndipo ali ndi kawopsedwe ndi irritability. Iyenera kugwiridwa ndikusungidwa bwino kuti isakhudzidwe ndi zinthu zoyaka komanso kutentha kwambiri.
-Pogwiritsa ntchito ndi kutaya pawiriyi, chonde tsatirani zofunikira za njira zoyendetsera chitetezo ndi malamulo ndi malamulo oyenera.
