Bisphenol A chuahnak ah a biapi mi uknak thil hna
Thilri thianhlimnak kongah, phenol le acetone, bisphenol A chuahnak caah a biapi bikmi thilri an si caah, an thianhlimnak cungah fek tein uknak an herh. Phenol thianhlimnak cu 99.5% nak tlawm lo ding a si, cun acetone thianhlimnak cu 99% nak tam a phan awk a si. A thiangmi thilri nih thil thurhnawm nih thil sining a thlen khawhnak kha a zorter khawh i thil sining tluang tein a kal khawhnak hnga a bawmh khawh.
Reaction lum le kih uk khawhnak cu a biapi tuk. Condensation thlennak lumnak cu a tlangpi in 40 – 60°C karlak a si. Hi lumnak tlukruannak chung ah, lehrulhnak rate le thilchuak thim khawhnak nih tlukruannak ttha a phan kho. A lin tukmi asiloah a niam tukmi nih bisphenol A BPA chuah khawhnak le a tthatnak kha a hnorsuan lai. Catalyst cawlcanghnak le thim khawhnak nih lehrulhnak lam kha a khiah. Sulfuric acid tibantuk hman tawnmi acidic catalysts nih an tlawmtam le an zat kha a dikthliar in hman a hau. A tlangpi in, sulfuric acid a tlawm le tam cu a tlawmpal chung ah aa thleng lengmang, cun a tlawm le tam cu thilri hmanmi dihlak ah aa telmi a si, cucaah catalyst nih a ttha bikmi rian a ttuan khawh. Reaction pressure nih bisphenol A BPA chuahternak zong a hnorsuan. Aa tlakmi hneknak cu 0.5 – 1.5 MPa a si. A fekmi hneknak pawngkam nih cun lehrulhnak system a fekmi a kilven i thilri thlennak le lehrulhnak tthanchonak a thanchoter. Thilri zat cu thlennak tthatnak he direct in aa pehtlai. Phenol le acetone i molar ratio cu 2.5 – 3.5:1 ah uk a si tawn. A dikmi zat nih thilri hna kha tling tein a lehrulh khawh, bisphenol A BPA chuahmi a karhter khawh, cun a chuakmi thilri hna kha a zorter khawh.

Bisphenol A BPA remhnak nih hriamnam thazaang, hliah le hruk khawhnak a tthanter, a harmi zuamcawhnak hna tawnghtham awkah timhcia a si.

Bochan tlak chemical thilri cawk na duh ahcun, “a ttha mi chemical” ah a biapi in a chiahmi le kum 20 chung rian a ttuan cangmi Shandong Pulisi Chemical Co., Ltd. kha kawl.
