1、Designation: D1319 14Standard Test Method forHydrocarbon Types in Liquid Petroleum Products byFluorescent Indicator Adsorption1This standard is issued under the fixed designation D1319; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revisio
2、n, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This test method
3、 covers the determination of hydrocar-bon types over the concentration ranges from 5 to 99 volume %aromatics, 0.3 to 55 volume % olefins, and 1 to 95 volume %saturates in petroleum fractions that distill below 315C. Thistest method may apply to concentrations outside these ranges,but the precision h
4、as not been determined. Samples containingdark-colored components that interfere in reading the chro-matographic bands cannot be analyzed.NOTE 1For the determination of olefins below 0.3 volume %, othertest methods are available, such as Test Method D2710.1.2 This test method is intended for use wit
5、h full boilingrange products. Cooperative data have established that theprecision statement does not apply to narrow boiling petroleumfractions near the 315C limit. Such samples are not elutedproperly, and results are erratic.1.3 The applicability of this test method to products derivedfrom fossil f
6、uels other than petroleum, such as coal, shale, ortar sands, has not been determined, and the precision statementmay or may not apply to such products.1.4 This test method has two precision statements depictedin tables. The first table is applicable to unleaded fuels that donot contain oxygenated bl
7、ending components. It may or maynot apply to automotive gasolines containing lead antiknockmixtures. The second table is applicable to oxygenate blended(for example, MTBE, ethanol) automotive spark ignition fuelsamples with a concentration range of 1340 volume percentaromatics, 433 volume percent ol
8、efins, and 4568 volumepercent saturates.1.5 The oxygenated blending components, methanol,ethanol, methyl-tert-butylether (MTBE), tert-amylmethylether(TAME), and ethyl-tert-butylether (ETBE), do not interferewith the determination of hydrocarbon types at concentrationsnormally found in commercial ble
9、nds. These oxygenatedcomponents are not detected since they elute with the alcoholdesorbent. Other oxygenated compounds shall be individuallyverified. When samples containing oxygenated blending com-ponents are analyzed, correct the results to a total-sample basis.1.6 WARNINGMercury has been designa
10、ted by manyregulatory agencies as a hazardous material that can causecentral nervous system, kidney and liver damage. Mercury, orits vapor, may be hazardous to health and corrosive tomaterials.

Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 aromaticsthe volume % of monocyclic and polycy-clic aromatics, plus aromatic olefins, some dienes, compoundscontaining sulfur and nitrogen, or higher boiling oxygenatedcompounds (excluding those listed in 1.5).3.1.2 olefinsthe
20、volume % of alkenes, plus cycloalkenes,and some dienes.3.1.3 saturatesthe volume % of alkanes, plus cycloal-kanes.4. Summary of Test Method4.1 Approximately 0.75 mL of sample is introduced into aspecial glass adsorption column packed with activated silicagel. A small layer of the silica gel contains
21、 a mixture offluorescent dyes. When all the sample has been adsorbed on thegel, alcohol is added to desorb the sample down the column.The hydrocarbons are separated in accordance with theiradsorption affinities into aromatics, olefins, and saturates. Thefluorescent dyes are also separated selectivel
22、y, with the hydro-carbon types, and make the boundaries of the aromatic, olefin,and saturate zones visible under ultraviolet light. The volumepercentage of each hydrocarbon type is calculated from thelength of each zone in the column.5. Significance and Use5.1 The determination of the total volume %
23、 of saturates,olefins, and aromatics in petroleum fractions is important incharacterizing the quality of petroleum fractions as gasolineblending components and as feeds to catalytic reformingprocesses. This information is also important in characterizingpetroleum fractions and products from catalyti
24、c reforming andfrom thermal and catalytic cracking as blending componentsfor motor and aviation fuels. This information is also importantas a measure of the quality of fuels, such as specified inSpecification D1655.6. Apparatus6.1 Adsorption Columns, with precision bore (“true bore” IPdesignation) t
