Refractive, dispersive and thermo-optic properties of twelve organic solvents in the visible and near-infrared, Appl. In optics, the refractive index (also known as refraction index or index of refraction) of a material is a dimensionless number that describes how fast light travels through the material. The index of refraction of toluene and methanol at different mol fractions were determined. Mole % Methanol versus Temperature: vapor – liquid … C12H14O4 (Diethyl phthalate, DEP) A complete experimental analysis on the use of Ge–B co-doped fiber Bragg grating sensor for a concentration and refractive index measurement is presented.

C2H4 (Ethylene) This research has investigated the use of a novel FBG sensor for online monitoring of concentration and refractive index of methanol. Artificial neural network (ANN) algorithm with two hidden layers. It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol. © 2016 Taiwan Institute of Chemical Engineers. All rights reserved. The obtained correlation satisfactorily represents the experimental refractive index data and can be reliably used to predict the refractive index of other binary systems containing the considered cation and anions and the studied alcohols. C2H3N (Acetonitrile) (C2H6OSi)n (Polydimethylsiloxane, PDMS) C4H9OH (Butanol) Page was last modified on March 16 2011, 23:59:46. Knowing a refractive index can help you (a) identify the medium in a liquid or (b) measure the purity and concentration of a medium in that liquid. The refractive index data were correlated as function of temperature, mole fraction, number of carbon atoms in the cation, number of atoms in the anion, number of hydrogen atoms in the anion and number of carbon atoms in the alcohol. The 6-6-9-1 neural network architecture was found to be the best network using two hidden layers Diffusion coefficient. The Refractive Index - n - of a medium is a measure for how much the velocity of light is reduced inside the medium. B 116, 617-622 (2013) Data [ Expressions for n ] [ CSV - comma separated ] [ TXT - tab separated ] [ Full database record ] El-Kashef 2000: n 0.4-0.8 µm C5H11OH (Pentanol, amyl alcohol) (C2H3Cl)n (Polyvinyl chloride, PVC) CH4 (Methane)   The obtained correlation satisfactorily represents the experimental refractive index data tested. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Refractive index of the eluent methanol/water (3:1 v/v) is n D = 1.336 [34]. To this end, understanding their physico-chemical properties is of high importance. Contact UsTalk to our product specialists:800-953-7626sales@lesman.com. Many materials have a well-characterized refractive index, but these indexes depend … ��t��,p! Refractive, dispersive and thermo-optic properties of twelve organic solvents in the visible and near-infrared, Appl. CH3OH (Methanol) To this end, understanding their physico-chemical properties is of high importance.

C6H5NO2 (Nitrobenzene) Artificial neural network (ANN) algorithm with two hidden layers. C6H14 (Hexane) C8H8O3 (Methyl salicylate) Copyright © 2020 Elsevier B.V. or its licensors or contributors. Using ANN, a total of 752 data points were used in the calculation and to obtain the optimum neural network parameters. It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol. The total reflection critical angle method is used to measure the refractive index of the solution, and then the concentration of the measured liquid and performance are calibrated. Refractive Index versus Volume (%) methanol - Simple distillation 4. Phys. When light passes through a medium, it bends, and normally at a predictable angle. C6H12 (Cyclohexane) CCl4 (Carbon tetrachloride) The refractive index data were correlated as function of temperature, mole fraction, number of carbon atoms in the cation, number of atoms in the anion, number of hydrogen atoms in the anion and number of carbon atoms in the alcohol. 8�ׯ���@�B�ʽ Refractometer Calibration Curve MeOH/water Refractive Index-Bausch & Lomb 1.342 1.34 1.338 1333B6 1.334 13332 1.33 1.328 1.3318 R0.9972 1.326 1.324 + 0 0.2 0.4 0.6 0.8 MeOH Content (mole fraction) … Methanol anhydrous, 99.8%; CAS Number: 67-56-1; EC Number: 200-659-6; Synonym: Methyl alcohol; Linear Formula: CH4O; find Sigma-Aldrich-322415 MSDS, related peer-reviewed papers, technical documents, similar products & more at Sigma-Aldrich.
