Designation:D527400(Reapproved 2014)Standard Guide forAnalysis of 1,3Butadiene Product1This standard is issued under the fixed designation D5274;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,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.1.Scope1.1 This guide covers the analysis of 1,3butadiene prod-ucts produced in North America.It includes possible compo-nents and test methods,both ASTM and other,either actuallyused or believed to be in use,to test for these components.Thisguide is not intended to be used or construed as a set ofspecifications for butadiene products.1.2 The values stated in SI units are to be regarded asstandard.The values given in parentheses are for informationonly.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D1025 TestMethodforNonvolatileResidueofPolymerization-Grade ButadieneD1157 Test Method for Total Inhibitor Content(TBC)ofLight HydrocarbonsD1550 Standard ASTM Butadiene Measurement TablesD2384 Test Methods for Traces of Volatile Chlorides inButane-Butene MixturesD2426 Test Method for Butadiene Dimer and Styrene inButadiene Concentrates by Gas ChromatographyD2593 Test Method for Butadiene Purity and HydrocarbonImpurities by Gas ChromatographyD3246 Test Method for Sulfur in Petroleum Gas by Oxida-tive MicrocoulometryD3700 Practice for Obtaining LPG Samples Using a Float-ing Piston CylinderD4178 Practice for Calibrating Moisture AnalyzersD4423 Test Method for Determination of Carbonyls in C4HydrocarbonsD4468 Test Method for Total Sulfur in Gaseous Fuels byHydrogenolysis and Rateometric ColorimetryD4629 Test Method for Trace Nitrogen in Liquid PetroleumHydrocarbons by Syringe/Inlet Oxidative Combustion andChemiluminescence DetectionD4864 Test Method for Determination of Traces of Metha-nol in Propylene Concentrates by Gas ChromatographyD5799 Test Method for Determination of Peroxides in Buta-diene3.Terminology3.1 Definitions:3.1.1 1,3-butadienehydrocarbon product containing morethan 99%1,3-butadiene.3.2 Symbols:3.2.1 BHTbutyl hydroxy toluene.3.2.2 GCgas chromatography.3.2.3 pTBCparatertiary butyl catechol.3.2.4 4VCH-14-vinyl cyclo hexene(1,3-butadiene dimer).4.Significance and Use4.1 This guide is intended to provide information on thepossible composition of 1,3-butadiene products and possibleways to test them.Since there are currently not enough ASTMstandards for determining all components of interest,this guideprovides information on other potentially available test meth-ods.4.2 Although this guide is not to be used for specifications,it can provide a starting point for parties to develop mutuallyagreed-upon specifications that meet their respective require-ments.It can also be used as a starting point in finding suitabletest methods for 1,3-butadiene components.5.Sampling5.1 General:5.1.1 1,3-butadiene is a very reactive hydrocarbon.It reactswith oxygen to form peroxides and to polymerize.It alsodimerizes at a rate that is temperature dependent.Below 10C(50F),the dimerization rate is less than 1 mg/kg by mass/h;1This guide is under the jurisdiction of ASTM Committee D02 on PetroleumProducts,Liquid Fuels,and Lubricants and is the direct responsibility of Subcom-mittee D02.D0.04 on C4 Hydrocarbons.Current edition approved May 1,2014.Published July 2014.Originally approvedin 1992.Last previous edition approved in 2009 as D5274 00(2009).DOI:10.1520/D5274-00R14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 but,at 20C(77F),it increases to 3 to 4 mg/kg mass/h;and at40C(104F),to 14 to 20 mg/kg mass/h.1,3-butadiene is alsoclassified as toxic and as a potential health hazard,having beenfound carcinogenic to laboratory animals.Therefore,samplingof 1,3-butadiene must adhere to the following three principles:5.1.1.1 Minimize personnel exposure.See the appropriateOSHA Material Safety Data Sheet for guidance,5.1.1.2 Eliminate or keep to an absolute minimum theinclusion of oxygen during and after sampling,and5.1.1.3 Sample the product at as low a temperature aspossible,maintain the sample at a low temperature,andanalyze it as soon as possible.Do not allow it to sit outdoors inthe sun after sampling.5.1.2 In addition to 5.1.1.1 5.1.1.3,1,3-butadiene to beanalyzed for trace components should be sampled by atechnique that minimizes or elim
