COMPOSITION OF THE STANDARD SAMPLES FOR CONTROL AND DETERMINATION OF THE SHARE OF THE CHLOROORGANIC COMPOUNDS IN THE PETROLEUM Russian patent published in 2007 - IPC G01N33/22 

FIELD: analytic chemistry; petrochemical industry; the means of metrological support of the procedures of execution of the measurements at determination of the share of the chloroorganic compounds in the petroleum.

SUBSTANCE: the invention is pertaining to the analytical chemistry and may be used in the capacity of the means of metrological support of the procedures of execution of the measurements at determination of the share of the chloroorganic compounds in the petroleum. The standard sample for control of determination of the share of the chloroorganic compounds in the petroleum represents the mixture containing the paraffin hydrocarbon of the normal structure with the boiling temperature above 150°С and the chloroorganic compound being the chlorine derivative of the paraffins with the boiling temperature of 40-204°С or the chlorine derivative of the aromatic hydrocarbons with the boiling temperature of 150-204°С. At that the concentration of the chloroorganic compound makes 2·10^-5 -2·10^-2 %. The technical result of the invention is usage of the standard sample for control over determination of the share of the chloroorganic compounds in petroleum, the possibility to carry out the analysis by two methods: the microcoulometric titration and also the potentiometric titration not requiring usage of the expensive equipment, which will allow to exercise not only control of the lapses of the procedures of performance of the measurements, but also the metrology certification of the procedures of performance of the measurements, and the check of the measuring devices.

EFFECT: the invention will allow performance of not only control of the lapses of the procedures of the measurements performance, but also the metrology certification of the procedures of the measurements performance, and the check of the measuring devices.
