Since there are currently not enough ASTMstandards for determining all components of interest, this guideprovides information on other potentially available test meth-ods.

11、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. Sam

12、pling5.1 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;but, at 20C (77F), it increases to 3 to 4 mg/k

13、g mass/h; and at40C (104F), to 14 to 20 mg/kg mass/h. 1,3-butadiene is also1This guide is under the jurisdiction of ASTM Committee D02 on PetroleumProducts and Lubricants and is the direct responsibility of Subcommittee D02.D0.04on C4Hydrocarbons.Current edition approved Nov. 1, 2005.

Therefore, samplingof 1,3-butadiene must adhere

16、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,

17、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 eliminates loss of light comp

18、o-nents and concentration of heavy ones. The subsections belowlist some different sampling methods and principles. However,it is not the intent of this guide to list procedures that areapplicable to all sampling situations. It is strongly recom-mended that samples be obtained under the supervision o

19、f aperson with wide knowledge and experience in sampling1,3-butadiene.5.1.3 Also, even though this guide does not address thelocation of a sampling point in a line or vessel, the importanceof the proper sampling location cannot be overemphasized.5.2 Floating Piston CylinderPractice D 3700 meets thec

20、riterion of minimizing or eliminating loss of light componentsand concentration of heavy ones. However, some labs havesafety codes preventing use of rupture-disc piston containers.Alternative procedures must be used in these labs.5.3 Conventional “Outaging” MethodThe widely used“outaging” technique

21、(that is, the practice of removing aportion of the fluid contents from a conventional samplingcylinder after filling in order to provide expansion room)causes a partial loss of light components into the vapor space.Subsequent handling to recapture these light ends in the liquidphase of the sample, s

22、uch as repressurization of the cylindercontents with an inert gas, is usually successful, since 1,3-butadiene seldom contains noncondensables. However, if per-manent gases are present and are to be determined, an alternateprocedure may be required.5.4 Vaporization MethodsVaporization of the sample,

23、ei-ther at the source or in the lab prior to analysis, may cause lossof heavier components, if present, and concentration of lighterones. Also, since 1,3-butadiene is so reactive, the heat requiredto vaporize may cause undesirable changes in the compositionof the sample. For these reasons, vaporizat

24、ion is not recom-mended for 1,3-butadiene.5.5 Reactive ComponentsDetermination of reactive com-ponents, such as certain sulfur compounds, is generally be-lieved to require special sample containers, such as TFE-fluorocarbon-lined cylinders.6.
