SUPPLEMENTARY INFORMATION:
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 propylene glycol phenyl 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 propylene glycol phenyl 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: Propylene glycol phenyl ether.
(2) Petitioner: The Dow Chemical Company, an importer and exporter of propylene glycol phenyl ether.
(3) Proposed classification numbers:
(i) HTSUS number: 2909.49.15.00.
(ii) Schedule B number: 2909.49.0000.
(iii) CAS number: 770-35-4.
(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, propylene glycol phenyl ether is a propylene oxide and phenol based ether-alcohol solvent. Propylene glycol phenyl ether, a liquid, is used in a variety of applications including coatings and cleaning.
Propylene glycol phenyl ether is made from propylene, chlorine, sodium hydroxide, and benzene. Taxable chemicals constitute 91.00 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. Propylene glycol phenyl ether is made via the alkoxylation process (also known as ring opening of an epoxide) using phenol and propylene oxide. Propylene oxide is made by hydrochlorination (chlorine (Cl2), propylene (C3 H6), and sodium hydroxide (NaOH)). Phenol is made via the Hock process (sometimes called the cumene process). The Hock process has two stages. In stage 1, benzene (C6 H6) is alkylated with propylene (C3 H6) to make cumene (isopropyl benzene). In stage 2, cumene (C6 H5 (C3 H7)) is partially oxidized to make phenol (C6 H5 OH) and side product dimethyl ketone ((CH3)2 CHO).
Additional information on the production process:
- The propylene glycol phenyl ether alkoxylation reaction (phenol + propylene oxide) is base catalyzed, using a small amount of metal hydroxide. Once phenoxide is made, it is regenerated following conversion to the product in the presence of propylene oxide. Regenerated phenoxide in the presence of propylene oxide will perpetually react until all propylene oxide is consumed or the reaction is halted through the use of controls.
○ Since the amount of metal hydroxide used to produce propylene glycol phenyl 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.
(7) Stoichiometric material consumption equation, based on process identified as predominant method of production:
2 C3 H6 (propylene) + Cl2 (chlorine) + 2 NaOH (sodium hydroxide) + C6 H6 (benzene) + O2 (oxygen) → 2 NaCl + H2 O (water) + (CH3)2 CO dimethyl ketone + C9 H12 O2 (propylene glycol phenyl ether)
(8) Tax rate calculated by Petitioner, based on Petitioner's conversion factors for taxable chemicals used in production of substance:
(i) Tax rate: $13.16 per ton.
(ii) Conversion factors: 0.55 for propylene, 0.47 for chlorine, 0.53 for sodium hydroxide, and 0.51 for benzene.
(9) Public docket number: IRS-2024-0044.
