Abstract

The MSB - 3-Methyl-3-Sulfanylbutan-1-Ol is a thiol molecule which could be used as food additive flavor agent and encountered in the white wine, in the coffee perfume, in the passion fruit and in the cat urine where it’s the responsible of its strong odor characteristics. Its extraction from the cat-litter and the synthesis of a new material based on black citric acid polymers (pn), pozzolana and citric acid named PPCA (pn-pozzolana-citric-acid) was studied in the previous manuscript. This manuscript consisted to valorize the PPCA as material to extract and to retain the MSB - 3-Methyl-3-Sulfanylbutan-1-Ol molecule. Thus, reaction tests were done between a MSB - 3-Methyl-3-Sulfanylbutan-1-Ol solution and the PPCA. The first part of this manuscript treated the description of these reaction tests procedure and the various experimental conditions which was at ambient temperature, in the open air and at atmospheric pressure inside a container without a cover. It was also described on this first part the quantifications of the molecules and PPCA’s sites involved in this reaction such as citric acid residues, MSB, acid sites and basic sites which were especially considered as sites governing the reaction-extraction between the PPCA-material and the MSB - 3-Methyl-3-Sulfanylbutan-1-Ol molecules. The second part of this manuscript consisted on the analyzing of the previous reaction tests results which allowed to the evaluation of its kinetic parameters. In general, it was noted that the reacting basic sites increase as a primary product while the reacting acid sites evolved as a secondary product. Finally, a reaction mechanism governing the MSB extraction-reaction on the PPCA was proposed considering that the PPCA’s reactive sites acid were grouped into either acid sites either basic sites by Boëhm titration which could regenerated during the reaction. This proposed reaction mechanism was validated by the determination of the extraction-reaction kinetic constant k equals to 8E-4 superior to the kinetic constant determined by reaction results exploitation which is equals to 2.69E-08.
