Iingcebiso zasekuseni zemarike ye-anhydride ye-phthalic!
Imakethi ye-phthalate yezinto eziluhlaza isebenza kakuhle, imakethi ye-naphthalene yemizi-mveliso isebenza kakuhle nangokuqinileyo, inkxaso ecaleni kweendleko isasekho, ezinye iifektri zivaliwe ukuze zilungiswe, unikezelo lwasekhaya luncitshisiwe kancinci, umthwalo wokuqala osezantsi ulinganiselwe, ingqondo yemarike ilumkile, kwaye ukuthengwa kuyimfuneko nje, kwaye kulindeleke ukuba imakethi ye-phthalic anhydride iqhubeke kakuhle kwixesha elizayo.
