Isingeniso

I-Terephthalyl chloride inokusetshenziswa okuhlukahlukene. Kuyinto ephakathi ebalulekile ekuhlanganiseni kwezinhlobonhlobo zezinto eziphilayo, njenge-terephthalimide, engasetshenziswa ukulungisa i-cellulose acetate, odayi namanye amakhemikhali. Ngaphezu kwalokho, ingasetshenziswa futhi njenge-ejenti ye-acid chlorinating (isb, ukuguqula utshwala, ama-amine, njll., ibe yizinhlanganisela ezifana nama-ester, ama-amide, njll.).

 

I-Terephthalyl chloride iyinhlanganisela enobuthi, futhi ukuthintana noma ukuhogela kuyo kungase kubangele ukucasuka kwamehlo, isikhumba, kanye nomgudu wokuphefumula. Ngakho-ke, izinyathelo ezifanele zokuphepha ezifana nokugqoka ama-eyewear okuzivikela, amagilavu ​​namamaski okuzivikela kufanele kuthathwe uma usebenzisa i-terephthalyl chloride ukuze kuqinisekiswe ukuthi iqhutshwa endaweni enomoya omuhle.
