| titleOfInvention | The method of estimating the water content in technical glycerin |
| abstract | The method of estimating the water content in technical glycerin consists in the fact that from the tested technical glycerin, several standard solutions are made containing known different amounts of added water and the same amount of tested technical glycerin with unknown water content is prepared, and then for each prepared glycerin the value is determined refractive index at a certain temperature, preferably with a refractometer, using monochrome light. The water content in technical glycerin is defined as the absolute value of the quotient of the coefficient (b), i.e. the point of intersection of the axis (Y) by the determined straight line to the value of the directional coefficient (a) of the determined linear function, determining the water content in the tested technical glycerin, which is the measured value refractive index for pure glycerin for analysis reduced by the value of the refractive index for the test sample with a specified amount of water added to the tested technical glycerin multiplied by one thousand. Next, a graph is made of the relationship between the refractive index value and the water content in technical glycerin, after calculations are made, and the linear regression equation for the set of refractive index results is determined, which is used to calculate the estimated water content in the tested technical glycerin according to the formula (1 ), in which: x - water content in technical glycerin, b - conversion factor, a - conversion factor. |
