Preparation method for ion pair chromatographic reagent sodium 1-tetradecanesulphonate

The invention relates to a preparation method for ion pair chromatographic reagent sodium 1-tetradecanesulphonate. The method comprises the following steps: adding anhydrous sodium sulfite, water, 1-myristyl bromide and tetrapropylammonium bromide in sequence in a reaction container provided with a cooling reflux device and a mechanical stirring device, sulfonating for 16-24 hours, then evaporating water in a mixture after the sulfonation reaction through pressure reduction, drying and crushing remaining solid, putting in a Soxhlet extractor, extracting with absolute ethyl alcohol to generate a crude product, then recrystallizing the crude product with absolute ethyl alcohol, filtering and purifying twice to obtain a pure product, and finally drying for 2-4 hours to obtain a finished product. According to the preparation method, in the sulfonation reaction process of the sodium sulfite and the 1-myristyl bromide, the tetrapropylammonium bromide is taken as a crystal, and the activity of the 1-myristyl bromide is strengthened, so that the sulfonation reaction can be carried out successfully, the generation of byproducts is reduced, and the reaction time is obviously shortened.

Surface activities, foam properties, HLB, and krafft point of some n-alkanesulfonates (C14-C18) with different isomeric distributions

A homologue series of sodium secondary n-alkanesulfonates (C14, C16 and C18) were obtained by photosulfochlorination process with two different reaction conditions. Different length chains with different isomeric distributions of n-alkanesulfonates are expected to present variations in physicochemical properties. In this investigation, the relationships between their isomeric distribution and their chain length and micellar behaviors were thoroughly explored. Their CMC at different temperatures were determined using specific conductivity and surface tension measurements. Through surface tension isotherms, the surface activities (γCMC) were obtained. The surface absorption amounts (Cmax) and the molecular areas (Amin) were calculated using Gibb's equation. As expected, these surfactants exhibit good surface properties. It was shown that the CMC values increase with increasing the percentage of secondary isomers, with a surface tension decrease. It was also shown that the CMC values decrease with increasing chain length. The HLB values were calculated for each surfactant and the results obtained suggest that they are O/W emulsifiers. The foam properties of synthesized surfactants were evaluated and compared to those obtained for commercial samples. It was shown that the foamability is influenced both by the length of the hydrophobic moiety and the percentage of secondary isomers. It can be easily concluded that the C14 sulfonates show the best foaming properties independently of their isomeric distribution. The Krafft point values obtained indicate that the micellization and the surfactant solubility mainly depend on the proportion of secondary isomers and the length of hydrophobic moiety. AOCS 2012.
