ASTMASTM D5441 Analysis of Methyl tert-butyl ether (MtBE) by GCASTM Committee D02 on Petroleum Products and Lubricants has issued the Standard Method D5441 for the determination of the purity of methyltert-butyl ether (MtBE) by Gas Chromatography. This method provides a procedure to measure impurities in MtBE such as C 4 to C 12 olefins, methyl,isopropyl and tert-butyl alcohols, methyl sec-butyl & methyl tert-amyl ethers, acetone, and methyl ethyl ketones. The presence of these impurities inMtBE can have a direct effect upon the value of the MtBE as a gasoline additive. The following reference standards have been formulated to meetthe method specifications. Different packaging sizes are available to meet various sample testing capacities.MtBE Contaminant StandardLow ConcentrationD-5441 $ 30 / 1 x 1 mLD-5441-PAKSAVE 20% $ 120 / 5 x 1 mLD-5441-5ML$ 100 / 1 x 5 mLD-5441-5ML-PAKSAVE 20% $ 400 / 5 x 5 mL0.1% Wt./Wt. each in MtBE 12 comps.tert-Amyl methyl ethertert-Butanoltert-Butyl ethyl ether4,4-Dimethyl-2-neopentyl-1-penteneMethanol2-Methylbutane2-Methyl-2-butene2,2',4,6,6'-Pentamethyl-3-heptenePentanecis-2-Pentenetrans-2-Pentene2,4,4-Trimethyl-1-penteneMtBE Contaminant StandardHigh ConcentrationD-5441-10X$ 30 / 1 x 1 mLD-5441-10X-PAKSAVE 20% $ 120 / 5 x 1 mLD-5441-10X-5ML$ 100 / 1 x 5 mLD-5441-10X-5ML-PAKSAVE 20% $ 400 / 5 x 5 mL1% Wt./Wt. each in MtBE 12 comps.tert-Amyl methyl ethertert-Butanoltert-Butyl ethyl ether4,4-Dimethyl-2-neopentyl-1-penteneMethanol2-Methylbutane2-Methyl-2-butene2,2',4,6,6'-Pentamethyl-3-heptenePentanecis-2-Pentenetrans-2-Pentene2,4,4-Trimethyl-1-penteneASTM D5441Qualitative StandardD-5441-QUAL$ 145 / 1 x 1 mL0.1% Wt./Wt. each in n-Dodecane 33 comps.MethanolIsobutylenen-Butanetrans-2-butenecis-2-butene3-Methyl-1-buteneAcetoneIsopentane2-Propanol1-Pentene2-Methyl-1-butenen-Pentanetrans-2-Pentenet-Butanolcis-2-Pentene2-Methyl-2-buteneCyclopenteneMtBE2,3-Dimethyl-1-butene4-Methyl-cis-2-pentene2-MethylpentaneMethylethyl ketone3-Methylpentanesec-Butyl methyl etherETBETAME3,5-Dimethyl-1-hexene2,4,4-Trimethyl-1-pentene2,4,4-Trimethyl-2-pentene3,4,4-Trimethyl-trans-2-pentene2,3,4-Trimethyl-2-pentene4,4-Dimethyl-2-neopentyl-1-pentene2,2’,4,6,6’-Pentamethyl-3-hepteneQuantitative StandardD-5441-QUANT-R1$ 130 / 1 x 1 mL0.1% Wt./Wt. each in n-Dodecane 29 comps.Methanol (0.04 Wt/Wt)3-Methyl-1-buteneAcetoneIsopentane2-Propanol1-Pentene2-Methyl-1-butenen-Pentanetrans-2-Pentenet-Butanolcis-2-Pentene2-Methyl-2-buteneCyclopenteneMtBE2,3-Dimethyl-1-butene4-Methyl-cis-2-pentene2-MethylpentaneMethyl ethyl ketone3-Methylpentanesec-Butyl methyl etherEthyl tert-butyl etherTAME3,5-Dimethyl-1-hexene2,4,4-Trimethyl-1-pentene2,4,4-Trimethyl-2-pentene3,4,4-Trimethyl-trans-2-pentene2,3,4-Trimethyl-2-pentene4,4-Dimethyl-2-neopentyl-1-pentene2,2’,4,6,6’-Pentamethyl-3-hepteneMtBE Resolution Test MixD-5441-RES$ 20 / 1 x 1 mLD-5441-RES-PAKSAVE 20% $ 80 / 5 x 1 mLD-5441-RES-5ML$ 60 / 1 x 5 mLD-5441-RES-5ML-PAKSAVE 20% $ 240 / 5 x 5 mL1% Wt./Wt. each in MtBE 3 comps.trans-2-Pentenetert-Butanolcis-PenteneMemberAccuStandard is an active member in ASTM andstrives to keep abreast of ASTM method revisions.If our listed formulation does not meet the mostrecent method revision, please contact TechnicalSupport, for an updated product.294 AccuStandard is accredited to ISO/IEC 17025 and certified to ISO 9001
