Taw qhia
Aminobenzene sulfonic acid, tseem hu ua sulfamine phenol, yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm p-aminobenzene sulfonic acid:
Zoo:
Aminobenzenesulfonic acid yog dawb crystalline hmoov uas tsis muaj ntxhiab thiab soluble hauv dej thiab ethanol.
Kev Siv: Nws kuj tuaj yeem siv rau hauv kev sib txuas ntawm qee yam dyes thiab tshuaj lom neeg ua haujlwm.
Txoj kev:
Aminobenzenesulfonic acid tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm benzenesulfonyl chloride thiab aniline. Ua ntej, aniline thiab alkali yog condensed los ua m-aminobenzene sulfonic acid, thiab tom qab ntawd aminobenzene sulfonic acid yog tau los ntawm acylation cov tshuaj tiv thaiv.
Cov ntaub ntawv kev nyab xeeb:
Sib nrug los ntawm nws cov teebmeem ntawm qhov muag, tawv nqaij, thiab ua pa, aminobenzene sulfonic acid tsis tau qhia meej tias muaj tshuaj lom lossis txaus ntshai. Thaum siv lossis tuav cov aminobenzene sulfonic acid, ua kom muaj cua zoo, tsis txhob sib cuag nrog lub qhov muag thiab tawv nqaij, thiab hnav cov khoom tiv thaiv yog tias tsim nyog. Yog tias tsis pom kev noj lossis kov, nrhiav kev kho mob tam sim ntawd. Thaum khaws cia thiab khaws cia, nws yuav tsum tau khaws cia rau hauv qhov chaw qhuav, txias, kom deb ntawm hluav taws thiab lwm yam khoom tawg.
