DOCUMENT TYPE: Journal; (online computer file) CA Section: 1 (Pharmacology) The antibacterial activity against Staphylococcus aureus of long-chain fatty alcs. was investigated, with a focus on normal alcs. The antibacterial activity varied with the length of the aliph. carbon chain and not with the water/octanol partition coeff. 1-Nonanol, 1-decanol, and 1-undecanol had bactericidal activity and membrane-damaging activity. 1-Dodecanol and 1-tridecanol had the highest antibacterial activity among the long-chain fatty alcs. tested, but had no membrane-damaging activity. Consequently, it appears that not only the antibacterial activity but also the mode of action of long-chain fatty alcs. might be detd. by the length of the aliph. carbon chain.

The calcd. excess and deviation functions were further fitted to the polynomial relation to est. the coeffs. and std. errors. While the exptl. viscosity data was compared with the predicted values obtained from empirical expressions, the speeds of sound data was analyzed in term of Schaaffs' collision factor theory and Jacobson's intermol. free length theory of solns. The effects of n-alkanol chain length as well as the temp. on the excess molar volume were studied. .
