Resin Ɔkwan ne Hydrogen Chloride Ɔkwan Mfiridwuma Ho Ntotoho
(1) Mfaso a ɛwɔ resin kwan a wɔfa so yɛ adwuma no so ma Bisphenol A. a wɔde yɛ aduru bpa: 1 Ɛho nhia sɛ wɔde nnwinnade a ne bo yɛ den a ɛmma nsɛe di dwuma, na sika a wɔde hyɛ nnwinnade mu no sua; 2 Nsu fĩ kakraa bi na ɛba; 3 Ɛho nhia sɛ wɔsan nya catalyst no na wɔsan de di dwuma bio.
(2) Mfaso a ɛwɔ hydrogen chloride kwan a wɔfa so yɛ bisphenol A bpa no so: 1 Ade a ɛma nneɛma yɛ kɛse no yɛ adwuma kɛse, ɔhyew a ɛwɔ mu no sua, na efĩ kakraa bi na ɛba; 2 Nneɛma a wɔde yɛ nneɛma a wɔsakra no dodow yɛ kɛse; 3 Ɛho nhia sɛ wɔsan de acetone a ɛnyɛ adwuma bio di dwuma; 4 Phenol a ɛkyinkyini kɔ reactor no mu no sua koraa (wɔnsiw mpa no kwan), na ortho ne para isomers a ɛwɔ reactor no mu no nnyɛ crystallize; 5 Ɛho nhia sɛ wɔyɛ recrystallization biara, na ɛtew sika a wɔde hyɛ mu ne adwumayɛ ho ka so; 6 Nneɛma a ɛba akyi a reactor no de ba no sua, na ɛho nhia sɛ wɔde afiri a wɔde dannan nneɛma a emu yɛ duru bɛba.
Esiane sɛ wɔde wɔn ani asi mfaso a ɛwɔ catalyst dwumadi ne selectivity a ɛwɔ hydrogen chloride kwan no so nti, ion-exchange resin kwan no ama catalyst no atu mpɔn, na wɔyɛ condensation reaction no wɔ phenol-ketone ratio kɛse bi mu. Phenol yɛ ade a ɛma nneɛma yɛ adwuma ne ade a ɛma nneɛma yɛ adwuma, na ɛma wotumi paw condensation reaction no tu mpɔn. Wobetumi afa crystallization kwan no so atew efĩ a ɛwɔ condensation reaction product no mu de anya bisphenol A bpa nneɛma a ɛyɛ papa. Sɛ yɛhwɛ nnwinnade dodow a, ɔkwan a wɔfa so yɛ resin no te sɛ hydrogen chloride kwan no. Bere koro no ara mu no, ion-exchange resin kwan nhyehyɛe no asesa sintɔ ahorow a ɛwɔ hydrogen chloride kwan kwan no so, ɛwɔ nsɛe a ɛyɛ mmerɛw wɔ nnwinnade mu, na ɛma ahotoso a ɛwɔ nhyehyɛe no dwumadi mu no tu mpɔn a ɛmma sika a wɔde hyɛ mu no nkɔ soro. Enti, ion-exchange resin kwan a wɔfa so yɛ bisphenol A bpa no abɛyɛ mfiridwuma ne nkɔso akwankyerɛ titiriw.
