Taw qhia
Terephthalyl chloride muaj ntau yam kev siv. Nws yog ib qho tseem ceeb nruab nrab ntawm cov synthesis ntawm ntau yam organic tebchaw, xws li terephthalimide, uas yuav siv tau los npaj cellulose acetate, dyes thiab lwm yam tshuaj. Tsis tas li ntawd, nws kuj tuaj yeem siv los ua cov kua qaub chlorinating tus neeg sawv cev (piv txwv li, hloov cov cawv, amines, thiab lwm yam, rau hauv cov tshuaj xws li esters, amides, thiab lwm yam).
Terephthalyl chloride yog ib qho tshuaj lom, thiab kev sib cuag lossis nqus tau nws tuaj yeem ua rau khaus ntawm qhov muag, tawv nqaij, thiab ua pa. Yog li, kev ntsuas kev nyab xeeb tsim nyog xws li hnav looj tsom iav, hnab looj tes thiab lub ntsej muag tiv thaiv yuav tsum tau ua thaum siv terephthalyl chloride kom ntseeg tau tias nws ua haujlwm hauv qhov chaw muaj cua zoo.
