Indlela ye-Bisphenol A BPA Ye-Esidi Yesulfuric isebenta njani?
I-Bisphenoli A bpa Indlela Ye-Esidi Yesulfuri
iPhenol ne acetone kuhamba ngekuphendvula kwekuhlanganiswa ku sulfuric acid ngekuhlanganiswa lokukhulu lokungu 72.5%–73.0% ku 35–45°C. Lomkhicito ubese uyagezwa ngemanti, ube yi crystall, uhlukaniswe nge centrifugation, bese womiswa kwentela kutfola ibisphenol A lefanele ema resin epoxy lasetjentiswa jikelele kanye netintfo letivimbela lilangabi. Emazinga ekusetjentiswa ngelithani lemkhicito acishe abe ngemathani langu 0.925 ephenol, emathani langu 0.285 eacetone, kanye nemathani langu 0.500 esulfuric acid (98% wekuhlanteka).
Lendlela ye Bisphenol A bpa ifaka imishini lelula kakhulu kanye netinchubo. Nomakunjalo, ihlushwa kusetjentiswa kwetintfo letiluhlata letisetulu, lokuholela ekutseni kube netindleko letiphakeme temkhicito. Kuphindze kubangele kugcola kwetintfo tekusebenta, emaphayiphi, emavalvu, kanye nendzawo yekukhicita, ngesikhatsi kukhicita imfucuza lebalulekile. Ngetulu kwaloko, lizinga lemkhicito alihlangabetani netidzingo tekukhicita i-polycarbonate noma ema-resin e-epoxy lasesigabeni sekudla.
