Request To Add Substance to the List
(a) Overview. A petition was filed pursuant to Rev. Proc. 2022-26 (2022-29 I.R.B. 90), as modified by Rev. Proc. 2023-20 (2023-15 I.R.B. 636), requesting that diethylene glycol monomethyl ether be added to the list of taxable substances under section 4672(a) of the Internal Revenue Code (List). The petition requesting the addition of diethylene glycol monomethyl ether to the List is based on weight and contains the information detailed in paragraph (b) of this document. The information is provided for public notice and comment pursuant to section 9 of Rev. Proc. 2022-26. The publication of petition information in this notice of filing is not a determination and does not constitute Treasury Department or IRS confirmation of the accuracy of the information published.
(b) Petition Content.
(1) Substance name: Diethylene glycol monomethyl ether.
(2) Petitioner: The Dow Chemical Company, an exporter of diethylene glycol monomethyl ether.
(3) Proposed classification numbers:
(i) HTSUS number: 2909.44.01.10.
(ii) Schedule B number: 2909.49.0000.
(iii) CAS number: 111-77-3.
(4) Petition filing dates:
(i) Petition filing date for purposes of making a determination: June 13, 2024.
(ii) Petition filing date for purposes of section 11.02 of Rev. Proc. 2022-26, as modified by section 3 of Rev. Proc. 2023-20: July 1, 2022.
(5) Description from petition: According to the petition, diethylene glycol monomethyl ether is an ethylene based glycol ether solvent. Diethylene glycol monomethyl ether is a liquid used in a variety of applications including coatings and cleaning.
Diethylene glycol monomethyl ether is made from ethylene and methane. Taxable chemicals constitute 59.00 percent by weight of the materials used to produce this substance.
(6) Process identified in petition as predominant method of production of substance: Glycol ethers are predominantly produced by reacting an epoxide (typically ethylene oxide or propylene oxide) with an alcohol; this reaction process is referred to as alkoxylation. Diethylene glycol monomethyl ether (C5 H12 O3) is produced by the alkoxylation process using methanol (CH3 OH) and 2 equivalents of ethylene oxide (C2 H4 O). Methanol is made from syngas (carbon monoxide and dihydrogen). Carbon monoxide (CO) and dihydrogen (H2) are made by steam-methane reforming (CH4 and H2 O). Ethylene oxide (EO) is made from oxidizing ethylene (C2 H4).
Additional information on the production process:
- The diethylene glycol monomethyl ether reaction (methanol + EO) is base catalyzed, using a small amount of metal hydroxide to produce methoxide.
○ Since the amount of metal hydroxide used to produce propylene glycol methyl ether is very small, the metal hydroxide has been excluded from the stoichiometric material consumption equation; including the metal hydroxide would lead to a distorted conversion factor.
- Once methoxide is made, it is regenerated following conversion to the product in the presence of EO as follows:
○ Methoxide + 2 EO → diethylene glycol monomethyl ether-alkoxide
○ Diethylene glycol monomethyl ether-alkoxide + methanol → diethylene glycol monomethyl ether + methoxide (goes back to participate in the reaction above).
- Regenerated methoxide in the presence of EO will perpetually react until all EO is consumed or the reaction is halted through the use of controls.
(7) Stoichiometric material consumption equation, based on process identified as predominant method of production:
2 C2 H4 (ethylene) + O2 (oxygen) + CH4 (methane) + H2 O (water) → H2 (hydrogen) + C5 H12 O3 (diethylene glycol monomethyl ether)
(8) Tax rate calculated by Petitioner, based on Petitioner's conversion factors for taxable chemicals used in production of substance:
(i) Tax rate: $5.47 per ton.
(ii) Conversion factors: 0.47 for ethylene, 0.13 for methane.
(9) Public docket number: IRS-2024-0038.
