Title:
Process for producing
bisphenol A
The problem the inventor(s)
wanted to solve: Production of high quality, colorless
epoxy resins for production of transparent polycarbonates, with a use of process
characterized by competitive energy and raw-material consumption indexes.
Description.
New technology includes: novel unit of BPA synthesis by condensation reaction
of acetone and phenol, carried out with use of modified cation
exchanger catalyst; separation and raffination of
final product unit; new and effective by-products transformation unit and
modern phenolic water purification unit,
guaranteeing very low content of impurities (mainly phenol and acetone) in
waste water.
Presentation.
POSTER
Fields of application:
Manufacture of plastics, in particular polycarbonates, epoxy resins and also
obtaining various plastics additives like flame-retardants.
Advantages:
- possibility of manufacture of bisphenol A with
high selectivity and capacity of p,p’-BPA isomer. High purity of
the final product enables its application for formation of high quality, colorless
epoxy resins and for production of transparent polycarbonates. Process is
characterized by competitive energy and raw-material consumption indexes, it also causes no wastes problems.
Stage of development.
Choose one of the following: text only, design, prototype,
pre-production, production item.
Documentation available:
( ) No (x) Yes
If the answer is YES, give details such as: leaflet,
brochure, sample, video, website, etc.
