AMSC N/A FSC 6810 METRIC A-A-59231B 9 July 2012 SUPERSEDING A-A-59231A 17 January 2007 COMMERCIAL ITEM DESCRIPTION ETHANOLAMINES (MONOETHANOLAMINE AND TRIETHANOLAMINE), TECHNICAL The General Servic
3、es Administration has authorized the use of this commercial item description for all federal agencies. 1. SCOPE. This commercial item description (CID) covers technical grades of modified commercial monoethanolamine and triethanolamine. Monoethanolamine is intended for use as a decontaminant for rio
4、t control agent CS (ortho-chlorobenzylidene malononitrile) and for the chemical agent CS1 dispersing equipment. Monoethanolamine is also intended for the removal of carbon dioxide from air, other gases, and liquids by absorption. Triethanolamine is intended for use when an organic base is required,
5、as in maintaining alkalinity of water solutions to prevent corrosion in such equipment as boilers, pipes, and radiators. 2. CLASSIFICATION. The ethanolamines shall be of the following types as specified (see 7.3(b): 2.1 Type. Type I - Monoethanolamine (MEA) Type II - Triethanolamine (TEA) 3. SALIENT
6、 CHARACTERISTICS 3.1 Appearance. Ethanolamines shall be clear, viscous, and free of suspended matter in the liquid state when tested as specified in 3.3.1. When in solid form, ethanolamines shall have a white, crystalline appearance, without visual evidence of impurities or discoloration. 3.2 Chemic
7、al and physical characteristics. Ethanolamines shall conform to the chemical and physical characteristics of table I when tested as specified herein.

10、. Water, in accordance with any ASTM D1193, “Standard Specification for Reagent Water“ type and grade, and reagent grade chemicals shall be used throughout the tests. Where applicable, blank determinations shall be run and corrections applied where significant. Tests shall be conducted as follows: 3
11、.3.1 Appearance. Thoroughly mix the specimen and transfer 25 milliliters (mL) into a 50 mL test tube. Stopper the test tube and allow it to stand until the bubbles have disappeared completely. Examine by transmitted light for uniformity and for freedom from particles and foreign matter. 3.3.2 Specif
12、ic gravity. Measure the specific gravity of types I and II ethanolamine specimens at 20 C/20 C. Determine with a digital density meter calibrated to give the apparent specific gravity at the specified conditions or a specific gravity balance (chainomatic) adjusted to give a 1.000 value for the speci

Other approved methods per ASTM D891, “Standard Test Methods for Specific Gravity, Apparent, of Liquid Industrial Chemicals“, may be used. 3.3.3 MEA, TEA and DEA content. 3.3.3.1 Apparatus. Use a gas chromatographic method with temperature programmer, split injection sy

Use MEA, DEA and TEA of no less than 99.0 percent by weight purity in preparing the standard solutions. At least one
18、standard solution shall be prepared with concentrations near the required levels as shown in table I. If multiple standard solutions are used, they shall bracket the requirements shown in table I. For MEA testing, the standard solution shall be prepared to be approximately 0.50 percent DEA and 0.20
19、percent TEA with the remainder being MEA. For TEA testing, the standard solution shall be prepared to be approximately 0.50 percent DEA and 0.50 percent MEA with the remainder being TEA. The three peaks shall exit in the following order: MEA, DEA and TEA. Repeated injections of the standard solution
20、 shall be passed through the GC until the main peak areas are each reproducible to within 2 percent of the average result (for each peak). Additional trace peaks shall be present, but the area of those peaks shall not be greater than 10 percent of the area of either of the two minor peaks. This proc
21、edure gives the response factor of the GC apparatus for all three ethanolamines at the appropriate concentrations. Response factors may not be constant over a large range of concentrations and should either be determined for several concentrations or at the expected concentration of the samples to b
22、e analyzed. Standard solutions can also be made with the ethanolamines in a solvent such as 2-propanol. In that case, the actual samples of product under test must also be prepared with the same dilution so that the concentration of primary component (MEA or TEA) in the solvent is the same as that i
23、n the standard solutions. 3.3.3.4 Procedure. Ethanolamines are sensitive to oxygen present in the GC carrier gas. Use a high purity grade of helium carrier gas. In addition, it is recommended that an oxygen/moisture trap be installed in the carrier gas feed prior to the GC. Repeatedly inject identic
24、al volumes of the sample into the GC until the areas of the three main peaks are each reproducible to within 2 percent of the average result for each peak. Calculate the average peak area for the three major peaks. If diluted standards were prepared in step 3.3.3.3, then identical dilutions shall be
25、 prepared with the samples prior to analysis. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-59231B 4 3.3.3.5 Calculations. Calculate the percent by weight of MEA, DEA and TEA as follows: Percent by weight MEA in sample = C1 x A1 / S1 where: C1
