Hloov pauv, tus qauv CT6 tuav qhov qhab nia C tawg-pov thawj, npog cov tseev kom muaj ntawm BT4 thiab muaj feem xyuam rau cov aav nrog cov roj txaus ntshai zoo li hydrogen thiab acetylene. T6 khoom siv yuav tsum ceev qhov chaw kub tsis muaj siab dua 85 ° C.
Nyob rau hauv cov nqe lus ntawm kub pawg, T6 sawv cev rau theem kev nyab xeeb tshaj plaws, hais qhia tias ib qho khoom siv hluav taws xob qis dua yog qhov zoo dua.
Raws li qhov tshwm sim, CT6 muaj kev ua pov thawj zoo dua-ntawv pov thawj.
