Bisphenol A (BPA) ubedo piny ma pire tek pi yubu polycarbonates, epoxy resins, man polyesters ma tek tek. Jutiyo kudu bende calu PVC stabilizer, plastic antioxidant, UV absorber, fungicide, man mukende mapol.
Calu piny ma tiyo ku yore madwong, BPA jutiyo kudu lee iyubu epoxy resins, polycarbonates, polyester resins, polyphenylene ether resins, man polysulfone resins. Mi medo, etiyo calu piny ma jwigo polyvinyl chloride (PVC), piny ma jwigo lyethu i plastik, piny ma jwigo UV, piny ma jwigo lum, man piny ma jwigo dongo i rubber.

Bisphenol a bpa Acid-Catalyzed Process
I yore mi acid-catalyzed, catalysts ubedo sulfuric acid, hydrochloric acid, nyo hydrogen chloride gas.
Lembe ma jutiyo kudu ku sulfuric acid calu catalyst utiye ku ngwec ma yot, juyike i kettle acel, etiyo kare ku kare, epe ku yeny mi dwoko phenol, man etiye ku lim manok. Ento, etiye ku piny madwong ma wok kud i iye, rwom pa bisphenol A bpa marac, tic ma lee, wel madwong pa piny adek ma rac (waste gas, waste water, man solid waste), nyai pa jam tic, man nyak ma nok. Yore mi sulfuric acid juwodhe woko i ngom mawoko i oro 1960.
Yore ma tiyo ku hydrochloric acid nyo hydrogen chloride gas calu catalyst julwonge ni hydrochloric acid. Yore mi hydrochloric acid utiye ku yore mi yubu piny ma dongo man ecopu bedu kare ku kare nyo kare ku kare. Tic ku piny ma jutiyo kudu man tic pa lwak utiye piny, man piny ma juyubu copo bedu maber ingey yike, ma jutiyo kudu pi yubu polycarbonate. Ni lembe ma tek pa hydrochloric acid, piny ma mitere pi jam tic, pipelines, man jam tic utiye malo, ci wel piny ma jutiyo kudu man gwoko piny utiye malo. Calu yore mi sulfuric acid, piny adek eni rac. Tic mi hydrochloric acid ubedo yore madit mi yubu piny i ng'om zoo i kind oro 1970 ku 1980.
