METHOD FOR DETERMINING PHYSICAL AND CHEMICAL PROPERTIES OF MULTICOMPONENT HYDROCARBON SYSTEMS Russian patent published in 2017 - IPC G01N33/26 G01N21/27 

FIELD: measurement equipment.

SUBSTANCE: in process of determining colour characteristics in the colorimetric system XYZ by recording the absorption spectra of the samples in the visible region of the electromagnetic spectrum, then produce the transition from the colorimetric XYZ system colorimetric RGB system is determined by three coordinates of the red, green and blue colorimetric RGB system which linearly correlated with physical and chemical properties of the objects, and determine the physicochemical properties of the formula: Z=a₁r+a₂g+a₃b, where Z - is one of the physicochemical properties: the relative density, average molecular weight, the activation energy of viscous flow and coking by Kondarsonu; r, g, b - coordinates of the RGB colour; a₁, a₂ and a₃ - the numerical coefficients.

EFFECT: improved accuracy and reliability, acceleration determination.
