Piny ma pire tek ma jwigo Bisphenol A
I lembe pa leng pa piny ma jutiyo kudu, phenol ku acetone, calu piny ma jutiyo kudu pi yiku bisphenol A, umitu jugwoke matek ikum leng pa piny migi. Leng pa phenol umitu kud ubed piny pa 99.5%, man leng pa acetone umaku ubed ma kadhu 99%. Jam tic ma leng copo dwoko piny peko pa piny ma reco ikum tic man eketho tic timo maber.
Gwoko lyethu pa piny ma jutimo piretek. Piny ma nyayu lyethu ubedo ikind 40 – 60°C. I kind rwom pa lyethu eni, kadhiri pa adwogi man yero pa piny copo bedu maber. Lieth ma malu nyo ma piny akeca copo nyayu peko ikum rwom pa bisphenol A BPA. Tic man yero pa catalyst nyuthu yo ma timo kudu tic. Jam tic ma pol kare tiyo kudu ma nyayu acid calu sulfuric acid mito nya juketh rwom man wel migi. Pol kare, kadhiri pa sulfuric acid lokore ikind rwom moku, man kadhiri utiye kadhiri pa kadhiri pa piny ma jutiyo kudu, kara catalyst timo tic maber. Peko mi timo lembe de nyayu bisphenol A BPA. Kabedo ma mitire utiye 0.5 – 1.5 MPa. Kabedo ma pressure ubedo maber konyo ni gwoko bedo maber pa reaction system man eketho mass transfer man reaction medire. Ratio pa piny utiye ku winjiri ku tic maber pa piny. Ratio pa molar pa phenol ku acetone pol kare juyike i 2.5 – 3.5:1. Ratio maber copo ketho piny ma jutiyo kudu timo tic maber, medo rwom pa bisphenol A BPA, man dwoko piny piny ma jutiyo kudu.

Bisphenol A BPA modification medu tego pa cuma, rwinyo man rwinyo, ayika ni cobo peko ma tek.

Ka imito wilu piny maber pa kemikol, nen Shandong Pulisi Chemical Co., Ltd., ma timo tic ikum "kemikol maber" man ubedu katiyo pi oro 20.
