Nanu ing prosesu ning pamaglalang ning bisphenol A?

Pamagkumpara ning Resin Method ampo Hydrogen Chloride Method Technologies
(1) Advantages ning resin method process para Bisphenol A bpa: 1 E na kailangan gamitan ing mamasang kasangkapan a e maka-corrosion, at mababa ing puhunan kareng kasangkapan; Mas ditak a wastewater ing gagawan; E na kailangang ibalik at i-recycle ing catalyst.
(2) Advantages ning hydrogen chloride method process para keng bisphenol A bpa: 1 Ing catalyst atin yang matas a aktibidad, ing temperatura ning reaksyun mababa ya, ampo ditak la mu reng impurities a mipalyari; Ing raw material conversion rate matas ya; E na kailangang i-recycle ing e me-react a acetone; Ing phenol circulation volume keng reactor ing pekamalati (ing bed ali ya makabara), ampo deng ortho ampo para isomers keng reactor e la mag crystallize; Ala nang kailangang recrystallization, makabawas keng gastus keng pamumuhunan ampo gastus keng operasyun; Ing dagul da reng by-products a gagawan ning reactor malati ya, at ala nang kailangan pang heavy component conversion device.
Para akit na ing advantage ning catalyst activity ampo selectivity ning hydrogen chloride method, ing ion-exchange resin method pepabuti ne ing catalyst, ampo ing condensation reaction gagawan de keng maragul a phenol-ketone ratio. Ing phenol parehu yang reactant ampo reaction solvent, na magpasanting keng selectivity ning condensation reaction. Deng impurities keng condensation reaction product malyari lang mikawani kapamilatan ning crystallization process para mika matas a kalidad a bisphenol A bpa products. keng bilang da reng kasangkapan, ing paralan ning resin kalupa ne ning paralan ning hydrogen chloride. At ing parehung panaun, ing ion-exchange resin method process binayu na ing kakulangan ning hydrogen chloride method process, atin yang mas mahina a corrosion kareng kagamitan, ampo mas masanting ing reliability ning operasyun ning sistema a alang daragul a gastus keng pamumuhunan. Uli na niti, ing ion-exchange resin method para keng pamaglalang bisphenol A bpa meging yang mainstream a teknolohiya ampo direksyun ning panyulung.
