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 info
4、rmationonly.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.

Significance and Use4.1 This guide is intended to provide information
10、 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 fo
11、r 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 ve
12、ry 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 F

15、28-2959. United States1but, 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 t
16、o 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, m
17、aintain 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 compo
18、-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 of
19、 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 D3700 meets thecri
20、terion 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 (t
21、hat 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, suc
22、h 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, ei
23、-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, vaporizatio
24、n is not recom-mended for 1,3-butadiene.5.5 Reactive ComponentsDetermination of reactivecomponents, such as certain sulfur compounds, is generallybelieved to require special sample containers, such as TFE-fluorocarbon-lined cylinders.6.
