Mawu Oyamba
2-Bromo-5-fluorobenzoic acid ndi organic pawiri. Ndi woyera crystalline olimba amene sungunuka mu organic solvents monga alcohols, ethers, ndi esters kutentha firiji.
Kugwiritsa ntchito 2-bromo-5-fluorobenzoic acid, yomwe nthawi zambiri imagwiritsidwa ntchito ngati yapakatikati mu kaphatikizidwe ka organic, imakhala ndi ntchito zina m'minda yamankhwala ndi mankhwala ophera tizilombo. Itha kugwiritsidwa ntchito popanga zinthu zosiyanasiyana zachilengedwe, monga ma ketoni onunkhira, esters, ndi amino acid. Itha kugwiritsidwanso ntchito ngati organic kuwala-emitting zakuthupi ndi zamadzimadzi kristalo zowonetsera zamadzimadzi.
Pali njira zingapo zokonzekera 2-bromo-5-fluorobenzoic acid. Njira yodziwika bwino ndikuyankhira p-bromobenzoic acid ndi boron pentafluoride kuti mupeze chinthu chomwe mukufuna. Zomwe zimachitika nthawi zambiri zimachitika mumlengalenga ndipo zimayendetsedwa ndi kutentha ndi nthawi.
Zambiri zachitetezo cha 2-bromo-5-fluorobenzoic acid: Ndi organic pawiri yokhala ndi zoopsa zina. Kukhudzana ndi khungu, maso, kapena kupuma kwa nthunzi yake kungayambitse mkwiyo. Kusamala koyenera kuyenera kutsatiridwa pogwira ndikugwiritsa ntchito, monga kuvala magolovesi oteteza mankhwala, magalasi, ndi zida zoteteza kupuma. Kukhudzana ndi ma oxidizing amphamvu ndi ma asidi amphamvu kuyenera kupewedwa kuti mupewe zotsatira za mankhwala. Panthawi yosungira ndi kuyendetsa, kutentha kwakukulu ndi moto wotseguka ziyenera kupewedwa.
