Yinga lulamisiwa hi condensation reaction ya phenol na acetone ehansi ka ntirho wa catalyst.

Bisphenol A yi fikelela ku ringanisela loku hetisekeke exikarhi ka ntsengo na matirhelo – nhlawulo lowunene wa ku tirha kahle ka ntsengo wa le henhla.Loko u lava ku xava switirhisiwa swa tikhemikhali leswi tshembekaka, hi kombela u lava Shandong Pulisi Chemical Co., Ltd., leyi kongomisaka eka “khemikhali ya khwalithi” naswona yi tirha ku ringana malembe ya 20.
