Txoj kev siv bisphenol A sodium ntsev ua haujlwm li cas?

Bisphenol A bpa Txoj kev ntsev sodium: Kauj ruam thawj zaug yog kev npaj ntsev sodium: ib qho me me ntawm bisphenol A yaj rau hauv cov kua dej methanol ntawm sodium hydroxide, nitrogen yog qhia rau cov tshuaj tiv thaiv ntsev, cov kuab tshuaj raug distilled tawm, thiab cov khoom raug ziab kom tau txais Bisphenol A BPA sodium ntsev. Kauj ruam thib ob suav nrog kev ntxiv cov phenoxide thiab epichlorohydrin tau txais rau hauv lub reactor ntawm qee qhov sib piv, ntxiv ib qho me me ntawm quaternary ammonium ntsev ua tus catalyst, thiab ua qhov tshuaj tiv thaiv ntawm 80 ~ 110 ° C. Tom qab cov tshuaj tiv thaiv, ntxuav dej thiab sib cais txheej raug ua kom tshem tawm NaCl. Tom qab ntawd, epichlorohydrin raug tshem tawm los ntawm kev nqus tsev kom tau txais cov khoom nyoos. Thaum kawg, cov kuab tshuaj organic siv rau kev rho tawm thiab ntxuav dej, cov tshuaj tiv thaiv raug cais ua txheej kom tau txais cov organic theem, thiab cov organic theem raug ziab thiab distilled kom tshem tawm cov kuab tshuaj organic, ua rau cov tshuaj Bisphenol A BPA-raws li epoxy resin zoo dua. Txawm li cas los xij, cov txheej txheem no nyuaj dhau, nrog rau kev nyuaj hauv kev sib cais catalyst, lub voj voog tsim khoom ntev, thiab yog li kev siv hauv kev lag luam tsawg.
