WebbSodium Alkane Sulfonate contains 32% actives at 20 ℃, cloud point (at 25%) 3 ℃, and surface tension (1 %) 31mN / m at 25 ° C, wetting power of 0.1% aqueous solution is 8s at 20 ° C and 4s at 50 ° C. Stable in alkaline, neutral, … WebbAmmonia is an amine, and amines have a pKa ~ 38, so the reaction goes from p K a ~ 25 to p K a ~ 38 which is a favorable p K a change and that is why this reaction would work: Looking at the p K a chart, you can see that the conjugate bases of alkanes and alkenes would also work to deprotonate the alkyne.
