A simple sulfonation process for Poly(phthalazinone ether ketone) (PPEK) was proposed with concentrated sulfonic acid. Various degrees of sulfonation (DS) were realized through the control of reaction ...
In order to study the influence of different sulfonation routes on its thermal and structural properties sulfonated polyaniline (SPAni) was prepared. FT-IR revealed that the formation of PAni salt or ...
This research explores the use of dielectric barrier discharge (DBD) plasma to enhance the catalytic performance of carbon materials via sulfonation. Traditional sulfonation methods require ...
Not only were the researchers able to find reaction conditions that resulted in high polymer sulfonation, minimal defects, and high efficiency with a mild sulfonating agent, this new method is also an ...

In this thesis, three different sulfonation reagents were used for the sulfonation reaction of m-phenylenediamine, and the reaction mechanisms and crystal structures of the three pathways were ...
With activated carbon as raw material, AC-Ph-SO3H was prepared after oxidation with nitric acid, modification with halogenated benzene and sulfonation with c ...
For the analysis of the sulfonation reactor system in the gaseous SO 3 sulfonation process, in the analysis process, the HAZOP method is first used to identify and analyze the existing accident risk ...
The aim of this work is to obtain polymer precursors based on styrene copolymers with distinct degrees of sulfonation, as an alternative material for fuel cell membranes. Acetyl sulfate was used to ...
The sulfonation pathway In the sulfonation pathway, an alkyl benzo [a]pyrene (benzo [a]pyrene containing CH 2 CH 3) is formed by alkylation and it is hydroxylated, forming a hydroxyalkyl benzo ...
