Mawu Oyamba

Terephthalyl chloride ili ndi ntchito zosiyanasiyana. Ndiwofunika kwambiri pakati pa kaphatikizidwe ka mitundu yosiyanasiyana ya mankhwala, monga terephthalimide, yomwe ingagwiritsidwe ntchito pokonzekera mapadi acetate, utoto ndi mankhwala ena. Komanso, itha kugwiritsidwanso ntchito ngati asidi chlorinating wothandizira (mwachitsanzo, kutembenuza alcohols, amines, etc., mu mankhwala monga esters, amides, etc.).

 

Terephthalyl chloride ndi mankhwala oopsa, ndipo kukhudza kapena pokoka mpweya kungayambitse mkwiyo wa maso, khungu, ndi kupuma. Choncho, njira zoyenera zotetezera monga kuvala zodzitchinjiriza za maso, magolovesi ndi masks otetezera ziyenera kutengedwa mukamagwiritsa ntchito terephthalyl chloride kuti zitsimikizire kuti zikugwiritsidwa ntchito pamalo abwino.
