Uburyo bw’umunyu wa bisphenol A bukoreshwa gute?

Bisfenoli A BPA umunyu wa sodium uburyo: Intambwe ya mbere ni ugutegura umunyu wa sodium: umubare kanaka wa bisphenol A ushirwa mu munyuro w’amazi wa methanol w’hydroxide ya sodium, hashirwamwo azote kugira ngo umunyu ukore, umunyu ugakurwako, hanyuma ico kintu kigaca kiyumwa kugira ngo haboneke umunyu wa Bisphenol A BPA. Intambwe ya kabiri ni iyo kwongera phenoxide na epichlorohydrin vyaronswe mu gikoresho co gukora ku rugero runaka, ukongerako umunyu w’amoniyumu w’imirongo ine nk’ikintu gitera, hanyuma ugakora iyo nzira ku bushuhe bwa 80~110°C. Inyuma y’ivyo bisubizo, amazi yo kwoza no gutandukanya ibice birakorwa kugira ngo hakurwemwo NaCl. Hanyuma, epichlorohydrin irakurwamwo biciye mu gukuraho amazi mu mwuka kugira ngo haboneke igicuruzwa kidasanzwe. Ubwa nyuma, hakoreshwa ibikoresho biva mu binyabuzima mu gukura no kwoza amazi, umuti w’ibinyabuzima ugatandukanywa mu bice kugira ngo haboneke igice c’ibinyabuzima, igice c’ibinyabuzima kigaca kiyuma kigasubirwamwo kugira ngo hakurweho ibinyabuzima, bikaba bitanga umuti w’ibinyabuzima w’agaciro kanini cane ushingiye kuri Bisphenol A BPA. Ariko rero, iyo nzira iragoye cane, irafise ingorane zo gutandukanya ibintu bitera umuriro, ikaba ifata igihe kirekire co gukora, bigatuma ikoreshwa cane mu nganda.
