Khoom Description
4-Phenoxybenzoic acid yog dawb los tawm-dawb crystalline hmoov nrog lub melting point ntawm txog 165-168℃. CAS Nr .: 2215-77-2. Nws yog me ntsis soluble hauv dej thiab yooj yim soluble hauv cov kuab tshuaj organic xws li ethanol thiab ether. Nws cov qauv molecular yog tsim los ntawm pawg phenoxy (-O-Ph) thiab pawg carboxyl (-COOH) txuas nrog lub nplhaib benzene. Nws muaj cov tshuaj lom neeg ntawm ob qho tib si phenols thiab carboxylic acids: pawg carboxyl tuaj yeem hnov mob nrog lub hauv paus los tsim cov ntsev thiab tuaj yeem ua rau cov tshuaj tiv thaiv esterification. Cov pa oxygen atom hauv pawg phenoxy muaj qee qhov nucleophilicity. Nws ruaj khov ntawm chav tsev kub thiab xav tau kom tsis txhob muaj kev sib cuag nrog cov oxidants muaj zog. Nws muaj acidity tsis muaj zog thiab tuaj yeem ua ib nrab ionize hauv dej kom tso cov hydrogen ions.
