The average
sulfonation degree [[bar.S].sub.x] in mole % of ~[SO.sub.3]H and standard deviation related to one aromatic ring obtained by means of elemental analysis of sulfonated PS pellets prepared at temperature 5[degrees]C.
Polystyrene is a very attractive base polymer for the production of low cost membranes in view the proximity of the aromatic units along the polymer chains, and the high resistance to degradation reactions occurring during the
sulfonation (11), (12).
In a second exploration, profound enhancement in interfacial adhesion were achieved at PS/poly(2-vinyl pyridine) interfaces once the styrene was functionalized by
sulfonation, creating sites which interact ionically with the pyridine nitrogen (24).
Thereby, in order to reduce the impact of alkyl chain length on performance characteristics of alpha olefin sulfonates, leading market players are adopting advanced technologies such as
sulfonation processing technology.
This surprising response, which depends on the degree of midblock
sulfonation, is attributed to a dramatic reduction in surface pH level that is remarkably effective against microbes with a typically anionic outer membrane.
The company has two new buildings that comprise the first fully integrated polymer and
sulfonation manufacturing facility in North America in more than 30 years and will bring previously lost production in Southern New Jersey to Camden.
With the increase of
sulfonation time from 2 h to 4 h and 6 h, the average particle size increased from 247 nm to 251 nm, 262 nm, and the surface adhesion increased.
Its proprietary core technologies involve alkylation,
sulfonation, sulfation and a number of other specialty operations, including the production of biocidal quats, tertiary amine derivatives, polymers and organometallic fuel additives.
as a new producer of linear alkylbenzene sulfonate, coconut fatty alcohol sulfate and sodium lauryl ether sulfate with a total
sulfonation capacity of 40,000 metric tons annually.
As a new manufacturer of linear alkylbenzene sulfonate (LABS), coconut fatty alcohol sulfate (CFAS) and sodium lauryl ether sulfate (SLES), BBBDI's project, which started operations in October, has a total
sulfonation capacity of 40,000 metric tons per year and employs 102 personnel.
