A small-angle neutron scattering study of nonionic surfactant molecules at the water-oil interface: area per molecule, microemulsion domain size, and rigidity was written by Sottmann, T.;Strey, R.;Chen, S.-H.. And the article was included in Journal of Chemical Physics in 1997.Application of 112-59-4 The following contents are mentioned in the article:
The small-angle neutron scattering (SANS) of bicontinuous microemulsions of 19 different water-n-alkane-CiEj (n-alkylpolyglycol ether) systems was measured. All scattering curves exhibit a broad scattering peak which permits determining the characteristic length scale ξ for bicontinuous structures at sym. water and oil volume fractions, i.e., φ=0.5. Various random models predict ξ = aδφ(1 – φ)/φc. ξ Is indeed determined to be inversely proportional to the surfactant volume fraction φc. Approximating the effective surfactant chain length δ by δ = vc/ac, where ac and vc are the area and the volume of the surfactant mol., the numerical value for a is determined to be a = 7.16, which is close to, but significantly different from those used in theor. models. The head group area ac at the water-oil interface is obtained from the large q part of the scattering curves. It is found to be independent of i and k, the carbon numbers of the alkyl chain of the surfactant and of the alkane, resp. However, it depends strongly, and nearly linearly, on the head group size j of the surfactant. Within exptl. error it is described by ac = 29.3 + 6.20j (Å2). This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Application of 112-59-4).
2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Application of 112-59-4
