The obtained correlation satisfactorily represents the experimental refractive index data tested. It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol. C3H6O (Acetone) (C37H24O6N2)n (Polyetherimide, PEI), Page The spectral changes in the grating response due to variation of concentration have been investigated in relation to new sensing configurations. 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. Refractive, dispersive and thermo-optic properties of twelve organic solvents in the visible and near-infrared, Appl. 8�ׯ���@�B�ʽ C11H12O2 (Ethyl cinnamate) The architecture consists of one input layer followed by hidden layer/s and an output layer being the last layer.Download : Download high-res image (143KB)Download : Download full-size image. Optical constants of C 2 H 5 OH (Ethanol) Myers et al. Using ANN, a total of 752 data points were used in the calculation and to obtain the optimum neural network parameters. Concentration and refractive index sensor for methanol using short period grating fiber. Artificial neural network (ANN) algorithm with two hidden layers. Knowing a refractive index can help you (a) identify the … A simple and low cost solution concentration and refractive index … B 116, 617-622 (2013), [Expressions for n] Mole % Methanol versus Temperature: vapor – liquid … The velocity of light in a medium can be expressed as © 2016 Taiwan Institute of Chemical Engineers. *�C���"H� C3H6(OH)2 (Propylene glycol) CHCl3 (Chloroform) Specifically, it determines the best neural architecture using the ANN along with the parameters associated with it, and it predicts the refractive index of the studied systems from the calculated empirical parameters.

Refraction is an effect that occurs between transparent materials of different densities. 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.

Methanol, also known as methyl alcohol amongst other names, is a chemical with the formula C H 3 O H (a methyl group linked to a hydroxyl group, often abbreviated MeOH). This study presents a model for predicting the refractive index of binary ionic liquid system containing alcohol using the artificial neural network (ANN) algorithm. 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. C5H12 (Pentane) C6H14 (Hexane) In recent years, a new class of solvent called ionic liquids had successfully demonstrated potential applications in industrial chemistry and chemical technology due to its desirable properties.
