He aha ke kaʻina hana o ka bisphenol A?

Hoʻohālikelike ʻana o ke ʻano Resin a me nā ʻenehana ʻenehana Hydrogen Chloride
(1) Nā pono o ke kaʻina hana resin no ka bisphenol A bpa① ʻAʻole pono e hoʻohana i nā lako hana kū i ka pala, a haʻahaʻa ka hoʻopukapuka kālā no nā lako; ② ʻAʻole nui ka wai hoʻoneoneo i hana ʻia; ③ ʻAʻole pono e hoʻihoʻi ʻia a hana hou ʻia ka mea hoʻoulu.
(2) Nā pono o ke kaʻina hana hydrogen chloride no bisphenol A bpa: ① He kiʻekiʻe ka hana o ka mea hoʻoulu, haʻahaʻa ka mahana o ka hopena, a he kakaikahi nā haumia i hana ʻia; ② Kiʻekiʻe ka wikiwiki o ka hoʻololi ʻana i nā mea maka; ③ ʻAʻole pono e hana hou ʻia ka acetone i hana ʻole ʻia; ④ ʻO ka nui o ke kahe ʻana o ka phenol i loko o ka reactor ka mea liʻiliʻi loa (ʻaʻole i ālai ʻia ka moena), a ʻaʻole e crystallize nā ortho a me nā para isomers i loko o ka reactor; ⑤ ʻAʻole koi ʻia ka recrystallization, e hōʻemi ana i nā kumukūʻai hoʻopukapuka kālā a me nā lilo hana; ⑥ He liʻiliʻi ka nui o nā huahana i hana ʻia e ka reactor, a ʻaʻohe pono no kahi mea hoʻololi ʻāpana kaumaha.
Ke kuhikuhi nei i nā pono o ka hana catalyst a me ke koho ʻana o ke ʻano hydrogen chloride, ua hoʻomaikaʻi ke ʻano resin ion-exchange i ka catalyst, a ua hana ʻia ka hopena condensation ma kahi ratio phenol-ketone nui. ʻO Phenol kahi reactant a me kahi solvent reaction, kahi e hoʻomaikaʻi ai i ke koho ʻana o ka hopena condensation. Hiki ke hoʻokaʻawale ʻia nā haumia i loko o ka huahana hopena condensation ma o ke kaʻina hana crystallization e loaʻa ai nā huahana bisphenol A bpa kiʻekiʻe. Ma ke ʻano o ka helu o nā lako, ua like ke ʻano resin me ke ʻano hydrogen chloride. I ka manawa like, ua hoʻololi ke kaʻina hana resin ion-exchange i nā hemahema o ke kaʻina hana hydrogen chloride, ua nāwaliwali ka palaho i nā lako, a hoʻomaikaʻi i ka hilinaʻi o ka hana ʻōnaehana me ka ʻole o ka hoʻonui ʻana i nā kumukūʻai hoʻopukapuka kālā. No laila, ua lilo ke ʻano resin ion-exchange no ka hana ʻana i bisphenol A bpa i ʻike nui ʻia i ka ʻenehana a me ke kuhikuhi hoʻomohala.
