Isicelo
Isetshenziswa kunjoloba yemvelo kanye ne-latex efana ne-styrene-butadiene, i-nitrile-butadiene, i-cis-butyl, i-polyisoprene, njll., ingayenza ibe nokumelana okuhle kwe-multi-flex kanye nokusebenza kwe-anti-cracking.Thuthukisa amandla okuqina, uthuthukise ukuvikeleka ezinsimbini eziyingozi njengomoya-mpilo oshisayo, i-ozone ne-manganese odongeni lwethusi, futhi ungabi nathonya ekuvuvukeni.Ihlanganiswe ne-antioxidant D, ingaxazulula izinkinga zokuguga ezihlukahlukene zemikhiqizo yerabha emnyama.Ngaphezu kwalokho, isetshenziswa njenge-polyethylene ne-polypropylene.Isetshenziswa njenge-antioxidant embonini yenjoloba

Indlela yokukhiqiza: I-Hydroquinone isabela ne-aniline ngaphansi kwe-catalysis ye-triethyl phosphate ku-280-300℃ kanye nengcindezi engu-0.7MPa isikhathi esithile.I-Chemicalbook isusa i-aniline eyeqile ngaphansi kwe-vacuum ephansi bese ihlakaza indawo emaphakathi ngaphansi kwe-vacuum ephezulu.Izinto ezisele emva kokukhishwa kwe-distillation ye-intermediate zisikiwe, zibe yimpuphu futhi zihlanganiswe njengomkhiqizo ophelile.Ukusabela kwe-synthesis kungokulandelayo
