CH3OH H-SO methyl salicylate acetylsalicylic acid NaOH aq. EtoH benzaldehyde acetone dibenzylideneacetone (dba) 2. For reactions where there is chemical equilibrium between reactants and products, a common way to increase yields is to apply Le Châtelier's Principle, and increase the amount of one reactant. This is particularly useful when one reactant is a cheap liquid that can be used as a solvent or co-solvent. Each of the two reactions shown (unbalanced) above employs a cheap organic liquid (methanol or acetone)...
