“…As represented in a previous paper 9,10 , the value of 1/τ c for each carbon atom of oleic acid, elaidic acid, or stearic acid obviously increases with increasing temperature. At any temperature, rotational movements for carbon atoms at the second position attached to the dimerized carboxyl group are considerably restricted, while those for other carbon atoms increase toward the end of the hydrocarbon chain.…”

“…They attribute this to the lower degree of order in MOL compared to OL. Under ambient conditions OL is an ordered liquid (Iwahashi et al, 2000(Iwahashi et al, , 1995(Iwahashi et al, , 1991 (Fig. 9), while MOL is probably an isotropic liquid under these conditions.…”

The oleic acid-ozone heterogeneous reaction system: products, kinetics, secondary chemistry, and atmospheric implications of a model system – a review

Abstract. The heterogeneous processing of organic aerosols by trace oxidants has many implications to atmospheric chemistry and climate regulation. This review covers a model heterogeneous reaction system (HRS): the oleic acidozone HRS and other reaction systems featuring fatty acids, and their derivatives. The analysis of the commonly observed aldehyde and organic acid products of ozonolysis (azelaic acid, nonanoic acid, 9-oxononanoic acid, nonanal) is described. The relative product yields are noted and explained by the observation of secondary chemical reactions. The secondary reaction products arising from reactive Criegee intermediates are mainly peroxidic, notably secondary ozonides and α-acyloxyalkyl hydroperoxide oligomers and polymers, and their formation is in accord with solution and liquidphase ozonolysis. These highly oxygenated products are of low volatility and hydrophilic which may enhance the ability of particles to act as cloud condensation nuclei (CCN). The kinetic description of this HRS is critically reviewed. Most kinetic studies suggest this oxidative processing is either a near surface reaction that is limited by the diffusion of ozone or a surface based reaction. Internally mixed particles and coatings represent the next stage in the progression towards more realistic proxies of tropospheric organic aerosols and a description of the products and the kinetics resulting from the ozonolysis of these proxies, which are based on fatty acids or their derivatives, is presented. Finally, the main atmospheric implications of oxidative processing of particulate containing fatty acids are presented. These implications include the extended lifetime of unsaturated species in the troposphere facilitated by the presence of solids, semi-solids or viscous phases, and an enhanced rate of ozone uptake by particulate unsaturates compared to corresponding gas-phase organics.Correspondence to: G. A. Petrucci (giuseppe.petrucci@uvm.edu) Ozonolysis of oleic acid enhances its CCN activity, which implies that oxidatively processed particulate may contribute to indirect forcing of radiation.

“…The dynamical structures and movements in the molecular scale for the components constructing their pure liquids or solutions have, however, not been so much precisely investigated. In general, fatty acids exist mostly as dimers in their liquid states and even in the non-polar solvents 5) , their dimers make clusters resembling smectic liquid crystal 6,7) . The clusters determine the overall physicochemical properties of the fatty acid in the liquid state [7][8][9] .…”

CH/.PI. Interaction between Benzene and Hydrocarbons Having Six Carbon Atoms in Their Binary Liquid Mixtures

Molecular interactions between benzene and hydrocarbons having six carbon atoms, such as hexane, cyclohexane and 1-hexene in their binary liquid mixtures were studied through the measurements of density, viscosity, self-diffusion coefficient, 13 C NMR spin-lattice relaxation time and 1 H NMR chemical shift. CH/p attraction between hexane and benzene in their binary mixture was observed in a relatively benzene rich region, whereas a special attractive interaction was not observed between cyclohexane and benzene. On the other hand, 1-hexene and benzene in their binary mixtures were characteristic in their self-diffusion coefficient behaviors: 1-hexene more strongly attract benzene not only by the CH/p attraction but also probably by the p/p interaction between the double bond in 1-hexene and the p-electron in benzene ring.
