Kodi njira ya bisphenol A sodium salt imagwira ntchito bwanji?

Bisphenol A bpa Njira ya mchere wa sodium: Gawo loyamba ndi kukonzekera mchere wa sodium: kuchuluka kwa bisphenol A kumasungunuka mu yankho la methanol lamadzi la sodium hydroxide, nayitrogeni imayikidwa kuti ipange mchere, chosungunulira chimasungunuka, ndipo chinthucho chimauma kuti chipeze mchere wa sodium wa Bisphenol A BPA. Gawo lachiwiri limaphatikizapo kuwonjezera phenoxide ndi epichlorohydrin zomwe zapezeka mu reactor pamlingo winawake, kuwonjezera kuchuluka kwa mchere wa quaternary ammonium ngati chothandizira, ndikuyendetsa zomwe zimachitika pa 80 ~ 110°C. Pambuyo pa zomwe zimachitika, kutsuka ndi madzi ndikulekanitsa zigawo kumachitika kuti achotse NaCl. Kenako, epichlorohydrin imachotsedwa ndi vacuum distillation kuti ipeze chinthu chosaphikidwa. Pomaliza, zosungunulira zachilengedwe zimagwiritsidwa ntchito pochotsa ndi kutsuka ndi madzi, yankho la reaction limagawidwa m'magawo kuti lipeze gawo la organic, ndipo gawo la organic limaumitsidwa ndikusungunuka kuti lichotse chosungunulira cha organic, zomwe zimapangitsa kuti resin ya Bisphenol A BPA-based epoxy resin ikhale yapamwamba kwambiri. Komabe, njirayi ndi yovuta kwambiri, yokhala ndi zovuta pakulekanitsa chosakaniza, nthawi yayitali yopangira, motero imagwiritsidwa ntchito pang'ono m'mafakitale.
