METHOD FOR DETERMINING PORFIRINS IN BITUMINIFEROUS COMPONENTS

摘要

the invention refers to a method of determining porfirinelor of bituminous components of rocks and ores by spectrophotometry in the infrared.in bettering that animal or vegetable to determine the nature thereof,50 g exhibit brought to a graininess of approximately 200 extract a mixture of 50 ml of n-hexane and toluene 50 ml for 30 minutes.at room temperature, after which the solution obtained by the method spectrofotometriei analyzed infrared, known.
