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.

Pangunahing Reaksyun
Ing Bisphenol a BPA synthesis reaction gagawan ne ning metung a molecule ning acetone ampo adwang molecule ning phenol lalam ning acidic catalytic a kundisyun. Ing reaction exothermic ya, at ing danum ing manimunang by-product. Ing reaksyun gagamit yang DOWEX cation exchange resin bilang catalyst. Ing catalyst ayni mekwa ya kaybat ning pamagtreat keng promoter ampo atin yang sapat a selectivity para keng Bisphenol a BPA synthesis. Ing phenol/acetone ratio keng reaction matas ya, at ing reaction gagawan de keng adiabatic reactor.
Ing reaksyun magproduce ya kareng makatuking impurities:
OP-BPA
Trisphenol
Dihydroxydihydroanthracene
Dianin Compounds
Ing mother liquor mibalik ya para mabalanse ing dagul da reng impurities para makasiguradung ing main reaction magproduce yang PP-BPA. Ing planta atin yang adwang parallel fixed-bed reactors, ing metung kareti keraklan gagamitan de para keng standby o regeneration. Nung mababa ya ing catalyst activity, ing metung a reactor milako ya keng production line, ing lumang catalyst milako ya, at bayu ya mibalik keng production line, ing bayung catalyst a me-treat keng promoter mi-load ya.
