Folasaga

Terephthalyl chloride e tele lona fa'aoga. O se mea taua tele i le tuʻufaʻatasia o le tele o vailaʻau faʻapitoa, e pei o le terephthalimide, lea e mafai ona faʻaaogaina e saunia ai le cellulose acetate, vali ma isi vailaʻau. E le gata i lea, e mafai foi ona faʻaaogaina e avea o se vailaʻau chlorinating acid (faʻataʻitaʻiga, e faʻaliliu ai le ava malosi, amines, ma isi, i mea faʻapitoa e pei o esters, amides, ma isi).

 

Terephthalyl chloride ose vaila'au oona, ma o le fa'afeso'ota'i po'o le inuina e ono mafua ai le ita o mata, pa'u, ma le manava. O le mea lea, e tatau ona faia ni faiga saogalemu e pei o le ofuina o mata, totigilima ma ufimata puipui pe a faʻaaogaina le terephthalyl chloride e faʻamautinoa ai o loʻo faʻagaioia i se nofoaga e faʻafefe lelei.
