Kodi njira ya Bisphenol A BPA Crystallization Process of Ion Exchange Resin Method ndi iti?

Bisphenol A bpa Njira Yopangira Makristalo ya Njira Yosinthira Ma Ion-Exchange Resin
Pali opereka ukadaulo wambiri wa patent wopanga bisphenol A pogwiritsa ntchito njira ya ion-exchange resin. Mu electrode ya reactor ya ukadaulo uliwonse wokhala ndi patent, p,p-bisphenol A BPA ndiye chinthu chofunikira cha BPA, pomwe o,p-BPA ndiye chinthu chachikulu chodetsa, chomwe chimakhudza mtundu wa chinthucho ndipo chimapangitsa kuti chikhale ndi yellowness index (YI) yapamwamba.
Pochotsa zonyansa kuchokera ku chinthu chochitapo kanthu, ukadaulo uliwonse wokhala ndi patent umagwiritsa ntchito ukadaulo wolekanitsa makristalo kuti upeze zinthu zapamwamba za bisphenol A bpa zomwe zimakwaniritsa zofunikira pakupanga polycarbonate (kuphatikiza kalasi yowala).
Ukadaulo wa makristalo umagawidwa m'magulu awiri. Gulu limodzi limagwiritsa ntchito njira yopangira makristalo a phenol ya magawo awiri; gulu lina limagwiritsa ntchito njira yopangira makristalo a phenol mu gawo loyamba ndi njira yopangira makristalo a madzi mu gawo lachiwiri.
