Ing kundisyun ning pamitipun para keng bisphenol A dapat yang mag-ikot keng core objectives ning "pamag-iwas keng pangasira, pamagsiguradung kaligtasan, ampo pamag-iwas keng pangasira ning kapaligiran".

Gamit ning Bisphenol A (BPA)

Ing bisphenol A (BPA) metung yang maulaga a materyales para keng pamaglalang kareng polycarbonates, epoxy resins, ampo high-temperature resistant polyesters. Magagamit ya naman antimong PVC stabilizer, plastic antioxidant, UV absorber, fungicide, atbp.
Bilang metung a compound a malyaring gamitan, ing BPA maralas yang magagamit keng pamaglalang epoxy resins, polycarbonates, polyester resins, polyphenylene ether resins, ampo polysulfone resins. Dagdag pa, magsilbi yang stabilizer para keng polyvinyl chloride (PVC), antioxidant keng plastic, UV absorber, agricultural fungicide, ampo anti-aging agent keng rubber.
Magagamit ya naman bilang antioxidant ampo plasticizer kareng pintura ampo tinta. King organic synthesis, ing BPA gaganap yang susi king pamaglalang epoxy ampong polycarbonate resins, at maralas yang magagamit antimong maulagang materyales para kareng high-molecular synthetic compounds, antimurin kareng anti-aging agents, plasticizer, ampong agricultural fungicides.

Bisphenol a bpa Acid-Catalyzed Process
Ing acid-catalyzed a prosesu, deng catalysts keraklan ilapin deng sulfuric acid, hydrochloric acid, o hydrogen chloride gas.
Ing prosesu gamit ing sulphuric acid bilang catalyst atin yang simpleng daloy, gagawan de keng metung a kettle, mag operate yang intermittently, e na kailangan ing phenol recovery, ampo atin yang mababang puhunan. Makanyan man, dakal ya by-products, e masanting a bisphenol A bpa quality, matas a konsumo, dakal a atlung basura (waste gas, waste water, ampo solid waste), grabing equipment corrosion, ampo mababa ing yield. Ing sulphuric acid a paralan mewala ya keng abroad keng 1960s.
Ing paralan a gagamit hydrochloric acid o hydrogen chloride gas bilang catalyst mayayaus yang hydrochloric acid method. Ing hydrochloric acid method atin yang mature a prosesu ning pamaglalang at malyari yang gawan intermittently o alang patugut. Mababa ing pamangailangan kareng raw materials ampo ing public engineering, at ing produktu malyari yang miras keng matas a kalidad kaybat nang me-refine, na magagamit keng pamaglalang polycarbonate. Uling keng masikan a corrosiveness ning hydrochloric acid, matas ing kailangan a materyal para kareng kagamitan, pipeline, ampo instrumentu, inya matas ing gastus keng pamumuhunan ampo pamaningat. Kalupa ning sulphuric acid a paralan, deng atlung basura seryusu la. Ing prosesu ning hydrochloric acid ing pekamaragul a paralan ning pamaglalang keng yatu kanitang dekadang 1970 ampong 1980.
