Izeluleko zasekuseni zemakethe ye-Phthalic anhydride!
Imakethe ye-phthalate yezinto ezingavuthiwe isebenza kahle, imakethe ye-naphthalene yezimboni isebenza ngokuqhubekayo futhi enamandla, ukusekelwa ohlangothini lwezindleko kusekhona, ezinye izimboni zivalekile ukuze zilungiswe, ukunikezwa kwendawo kuncishisiwe, umthwalo oqala phansi womfula ulinganiselwe, isimo sengqondo semakethe siqaphile, futhi ukuthengwa kuyadingeka, futhi kulindeleke ukuthi imakethe ye-phthalic ingase isebenze esikhathini esizayo se-anhydride.
