Mawu Oyamba
2-Bromo-5-chlorobenzoic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha pawiri:
Ubwino:
2-Bromo-5-chlorobenzoic acid ndi gulu lolimba. Zimatengera mawonekedwe a makhiristo oyera kapena achikasu pa kutentha. Ili ndi kukhazikika kwabwino kwa kutentha ndipo imatha kukhalapo mokhazikika pa kutentha kwakukulu. Pawiri ali mkulu kusungunuka mu organic solvents.
Gwiritsani ntchito:
2-Bromo-5-chlorobenzoic acid nthawi zambiri amagwiritsidwa ntchito ngati mankhwala ofunikira apakati mu kaphatikizidwe ka organic.
Njira:
2-Bromo-5-chlorobenzoic asidi nthawi zambiri amakonzedwa ndi bromination ndi chlorination wa asidi benzoic. Benzoic acid amayamba ndi bromine ndi sulfurous acid kupanga bromine benzoate, kenako amachitira ndi ferric chloride kupeza 2-bromo-5-chlorobenzoic acid.
Zambiri Zachitetezo:
2-Bromo-5-chlorobenzoic acid ndi organic pawiri yomwe ingakhale pachiwopsezo kwa anthu komanso chilengedwe. Kuyang'ana kapena kupuma movutikira kungayambitse kuyabwa kwa maso, khungu, ndi kupuma. Zida zodzitetezera zoyenera monga magolovesi, zishango zakumaso, ndi zodzitetezera ziyenera kuvalidwa pochita opaleshoni. Iyenera kugwiritsidwa ntchito ndikusungidwa pamalo abwino mpweya wabwino, kutali ndi moto komanso kutali ndi oxidants. Kulumikizana kulikonse kapena kulowetsedwa mwangozi kuyenera kuthandizidwa mwamsanga ndipo uphungu wachipatala uyenera kupezedwa. Njira zogwiritsira ntchito chitetezo chokwanira ziyenera kutsatiridwa pogwira ntchitoyi.
