Journal of Chemical & Engineering Data 2018, 63 (1) , 127-137. Refractive index database [about] Shelf ... Optical constants of C 2 H 4 (Ethylene) Loria 1909: Gas at 0 °C; n 0.523-0.668 µm. Temperature (K) A B C Reference Comment; 323. (Monoethylene Glycol / MEG) Monoethylene glycol (MEG) in its pure form, it is an odorless, colorless, syrupy liquid with a sweet taste. The following chart depicts this relationship for Ethylene Glycol. By way of illustration, a vacuum has a refractive index of 1.0, the refractive index of air (1013 mbar) is 1.000272, and drinking water has a refractive index of 1.333. 4 As concentration increases, refractive index increases. Refractive index is the measurement of that angle: the ratio of the velocity of light in the air to the velocity of light in a medium through which it passes. When light passes through a medium, it bends, and normally at a predictable angle.

Z. Kozma, P. Krok, and E. Riedle. Ethylene glycol, which is used to prepare coolants, has an index …

The higher the refractive index of a medium, the more strongly the light refracts.

Direct measurement of the group-velocity mismatch and derivation of the refractive-index dispersion for a variety of solvents in the ultraviolet, J. Opt. Both these solutions have a nearly linear relationship between concentration and refractive index. Refractive Index.

Refractive index of ethylene glycol solutions, This site is in construction. Polymer Refractive Index; Poly(hexafluoropropylene oxide) 1.3010: Poly(tetrafluoroethylene-co-hexafluoropropylene) 1.3380: Poly(pentadecafluorooctyl acrylate) Ethane-1,2-diol; 1,2-Ethanediol; Glycol; Ethylene Alcohol; Hypodicarbonous acid; Monoethylene glycol; External links . The concentration of the sugars is calculated as the remainder (100% - % water = % sugar). ) Optical constants of C 2 H 4 (OH) 2 (Ethylene glycol) Sani and Dell'Oro 2014: Dispersion formula; n,k 0.185-2.8 µm. Density, Viscosity, Refractive Index, and Speed of Sound in Binary Mixtures of Methyl Acetate + Ethylene Glycol or + Poly(ethylene glycol) in the Temperature Interval (298.15−308.15) K. Journal of Chemical & Engineering Data 1998, 43 (5) , 852-855. Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound with the formula (CH 2 OH) 2.It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. Density, Viscosity, Refractive Index, and Excess Properties of Binary and Ternary Solutions of Poly(ethylene glycol), Water, and Dipotassium Tartrate at 298.15 K and Atmospheric Pressure. Refractive index database [about] Shelf. Notice that the plot below shows the refractive index as a function of water (not sugar) in the mixture.

Ethylene Glycol: HOCH 2CH 2OH CAS Registry Number: 107-21-1 Synonyms: 1, 2-Ethanediol Glycol EG Monoethylene glycol Ethylene glycol is produced from ethylene, via the intermediate ethylene oxide. Both Ethylene Glycol and Propylene Glycol may be measured very accurately by refractive index. Soc. - 473. For more accuracy, the MISCO Palm Abbe digital refractometer can be equipped with a number of scales for reading ethylene glycol (EG) and propylene glycol (PG).

Oxygenated solvents are organic solvents containing oxygen molecules, created through chemical reactions from olefins. Ethylene Glycol Ethanol Methanol Honey contains a lot of sugar that can be determined by refractive index.

It is a traditional analog refractometer with scales for measuring both ethylene glycol (EG) and propylene glycol (PG) freeze points. The HI 96831 Ethylene Glycol Digital Refractometer is a rugged, portable, water resistant device that utilizes the measurement of refractive index to determine the percent volume and freezing point of ethylene glycol based solutions.

Ethylene Glycol Ethanol Methanol Honey contains a lot of sugar that can be determined by refractive index.
