The simultaneous presence of N-acyl-N-methylamide and carboxylate groups in the surfactant molecule produces some unique interfacial properties in aqueous media. These are ascribed to the steric effect of hydrogen bonding between the two groups. Properties of sodium N-dodecanoyl-N-methyl-Ξ²-alanate (
## Mixtures of cis-and trans-2-n-alkyl-5-carboxy-5-methyl -1,3dioxanes, 3a-3e, were obtained in the reaction of aliphatic aldehydes 1a-1e (from n-octanal to n-dodecanal) with 2,2-bis(hydroxymethyl)propionic acid (DMPA), 2, carried out in boiling n-hexane or in the isomerization reaction of an appr
