Isebenza njani indlela yeBisphenol A BPA Sulfuric Acid?
IBisphenol A i-bpa Indlela yeSulfuric Acid
I-Phenol kunye ne-acetone zifumana i-condensation reaction kwi-sulfuric acid enobunzima obuyi-72.5%–73.0% kwi-35–45°C. Emva koko imveliso ihlanjwa ngamanzi, i-crystallized, yahlulwe nge-centrifugation, ize yomiswe ukuze kufunyanwe i-bisphenol A efanelekileyo kwii-epoxy resins kunye ne-flame retardants. Amanani okusetyenziswa ngetoni nganye yemveliso amalunga ne-0.925 yeetoni ze-phenol, iitoni ze-0.285 ze-acetone, kunye neetoni ze-0.500 ze-sulfuric acid (98% ubumsulwa).
Le ndlela yeBisphenol A bpa inezixhobo kunye neenkqubo ezilula. Nangona kunjalo, inengxaki yokusetyenziswa kwezinto eziluhlaza okuphezulu, nto leyo ekhokelela kwiindleko eziphezulu zemveliso. Ikwabangela ukubola kwezixhobo, imibhobho, iivalvu, kunye nendawo yokuvelisa, ngelixa ivelisa inkunkuma eninzi. Ngaphezu koko, umgangatho wemveliso awuhlangabezani neemfuno zokuvelisa i-polycarbonate okanye i-epoxy resins yodidi lokutya.
