Iingcebiso zentengiso ye-Phthalic anhydride ekuseni!
Imakethi ye-phthalate yezinto ezikrwada iqhuba kakuhle, imakethi ye-naphthalene yeshishini iqhuba ngokuthe ngcembe kwaye ngamandla, inkxaso yecala leendleko isekhona, ezinye iifektri zivaliwe ukuze zilungiswe, unikezelo lwasekhaya luncitshisiwe kancinane, umthwalo oqalayo osezantsi ulinganiselwe, ingqondo yentengiso ilumkile, kwaye ukuthengwa kuyafuneka nje, kwaye kulindeleke ukuba imakethi yephthalic iqhube i-anhydride kungekudala.
