Synthesis and acid-base transformations of (4-styrylpyridinio)-alkanesulfonates

Chemistry of Heterocyclic Compounds, 1986
(4-Styrylpyridinio)alkanesulfonates were synthesized by condensation of 2-(4-methylpyridinio)- and 2-(4-ethylpyridinio)-1-ethanesulfonates with aromatic aldehydes, and also by quaternization of 4-styrylpyridine by sulfoalkylating agents. For the p- and o-hydroxystyrylpyridinium compounds in aqueous solutions, the pK a values were determined ...

Synthesis of Polyoxymethylene Dimethyl Ethers Catalyzed by Brønsted Acid Ionic Liquids with Alkanesulfonic Acid Groups

Industrial & Engineering Chemistry Research, 2014
Catalytic reaction of methylal (DMM) with trioxane (TOX) for preparation of polyoxymethylene dimethyl ethers (PODMEn, CH3O(CH2O)nCH3, where n > 1) was investigated in a series of Bronsted acid ionic liquids with alkanesulfonic acid groups. The structures, acidities, and properties of ionic liquids were experimentally characterized and theoretically ...

Synthesis and structure of grafted layer of silicas modified with alkanesulfonic acid

Russian Chemical Bulletin, 2003
A convenient method for preparation of silicas modified with alkanesulfonic acid through the reaction of NaHSO3 with the C2H3 groups grafted on the SiO2 surface was proposed. The influence of the carrier and the structure of the grafted layer on the modification process was studied by DRIFT, MAS NMR, and temperature-programmed desorption mass ...
