Indlela ye-bisphenol A ye-sodium salt isetjenziswa njani?

I-Bisphenol A BPA itswayi yesodiyamu indlela: Igadango lokuthoma kukulungiselela isawudo ye-sodium: inani elithileko le-bisphenol A liyancibilikiswa ngaphakathi kwesisombululo se-methanol samanzi se-sodium hydroxide, i-nitrogen ingeniswa ukusabela kokwakha itswayi, isisombululo siyavundiswa, bese umkhiqizo womiswe ukuthola i-Bisphenol A BPA itswayi le-sodium. Igadango lesibili lifaka hlangana ukungezelela i-phenoxide ne-epichlorohydrin etholakeleko ngaphakathi kwe-reactor ngesilinganiso esithileko, ukungezelela inani elithileko le-quaternary ammonium salt njenge-catalyst, nokuqhuba ukusabela ku-80~110°C. Ngemva kokusabela, ukuhlanza ngamanzi nokuhlukaniswa kwesendlalelo kwenziwa ukususa i-NaCl. Bese, i-epichlorohydrin isuswa ngokuvundiswa kwe-vacuum ukuthola umkhiqizo ongahlwengileko. Ekugcineni, iinsombululo eziphilako zisetjenziselwa ukukhipha nokuhlanza ngamanzi, isisombululo sokusabela sihlukaniswa sibe ziingqimba ukuthola isigaba se-organic, bese isigaba se-organic somiswa begodu sivundiswe ukususa isisombululo se-organic, okuveza i-Bisphenol A BPA-based epoxy resin yekhwalithi ephezulu. Kodwana, ikambiso le iyinkimbinkimbi khulu, inobudisi bokuhlukaniswa kwe-catalyst, umjikelezo omude wokukhiqiza, begodu ngalokho ukusetjenziswa okulinganiselweko emabubulweni.
