Monooleate, glycerol

Epo>y Compounds. Epoxidized soya oil (ESO) is the most widely used epoxy-type additive and is found ia most mixed metal stabilized PVC formulations at 1.0—3.0 phr due to its versatiHty and cost effectiveness. Other usefiil epoxy compounds are epoxidized glycerol monooleate, epoxidized linseed oil, and alkyl esters of epoxidized tall oil fatty acid. 

Abbreviations. aT = a-tocopherol, AC = aminocoumarin, ANS = l-anilino-8-naphthalenesulfonic acid, CTAB = cetyltrimethylammonium bromide, DPPC = dipalmitoylphosphatidylcholine, DPPH — l,l-diphenyl-2-picrylhydrazyl, DSHA = Ai-dansylhexadecylamine, GMO = glycerol monooleate, HC = hydrocoumarin, N,N -DOC = JV,JV -di(octadecyl)oxacarbocyanine, PC = phosphatidylcholine, p-CUO = pyrene caroboxaldehyde, SDES — sodium decyl sulfate, SDS — sodium dodecyl sulfate, STS = sodium tetradecyl sulfate. 

In glycerol monooleate/decane bilayers we find the steady-state conductance at zero current to be proportional to the first power of the ion concentration and to the second power of the ionophore concentration, as illustrated in Fig. 1. (The current-voltage characteristic is hyperbolic for all ionic species indicating that this molecule is in the equilibrium domain for the interfacial reactions, with the rate-limiting step being the ion translocation across the membrane interior.) The conductance selectivity sequence is seen to be Na>K>Rb>Cs, Li.

Numerous lubricity additives for fuel oils have been described (101). Caprotti et al. (102) disclosed an additive that is comprised of an ester of a carboxylic acid and an alcohol, wherein the acid has from 2 to 50 carbon atoms and the alcohol has one or more carbon atoms, e.g., glycerol monooleate. Although general mixtures are contemplated, no specific mixtures of esters were described. 

This progression fits well experimental data collected so far. In the binary glycerol monooleate-water system there is conclusive experimental evidence for the presence of a body-centred structure of symmetry laSd at lower water contents and a primitive cubic bilayer (symmetry Pn m) at higher water contents [28] (Fig. 4.15).
