The synthesis, characterization, and surface properties of soaptype amphiphiles comprising alkyl chains of 10-16 carbon atoms linked through an ether group to a glycerolamino acid hydrophilic head group is described. The surface properties of members of this series derived from histidine and tyrosine were compared with those of phenylalanine and tryptophan derivatives described previously and with those of conventional soaps. In all cases, the amino acid derivatives showed superior surface properties, and an interesting differentiation was discovered regarding the orientation of tryptophan derivatives.

Phosphate surfactants containing ether and hydroxyl groups were prepared by a simple reaction between the corresponding epoxide and the diethyl phosphate. The relationships between the structure and colloidal properties were evaluated in terms of the critical micelle concentration (CMC), γCMC, foaming ability, and water absorbing and holding abilities. Based on these results, it was concluded that the ether and hydroxy groups synergistically worked together to decrease the CMC and increase the foaming ability. The degree of neutralization remarkably affected the colloidal properties. The highly neutralized states showed a more positive effect on water holding power but an opposite effect on the foaming ability. Copyright
Synthesis of [14C]-Labelled glycidyl and glycerol ethers of aliphatic and aromatic alcohols.

The synthesis of [14C]-labelled glycidyl ethers and the corresponding glycerol ethers is described for the monofunctional compounds 1-dodecanol and ortho-cresol and the bifunctional compounds 4,4'-dihydroxy-3,3',5,5'-tetramethyl biphenyl and 1,6-hexanediol. The synthesis is based on reaction between the alcohol and [U-14C]-epichlorohydrin. The aromatic compounds have been converted to the corresponding glycidyl ethers by using sodium hydroxide and the aliphatic compounds by using tin(IV) chloride as a catalyst. Thus radio-labelled glycidyl ethers were obtained in yields between 50-80, with a chemical purity of > 92 and a radiochemical purity of > 95 by HPLC. The specific activities of the glycidyl ethers were approximately 0.2 mCi/mmol for the monofunctional compounds and approximately 0.4 mCi/mmol for the bifunctional compounds.
