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 di-isononyl adipate be added to the list of
taxable substances under section 4672(a) of the Internal Revenue Code
(List). The petition requesting the addition of di-isononyl adipate 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: Di-isononyl adipate.
The substance is also known as DINA.
(2) Petitioner: Exxon Mobil Corporation, an exporter of di-isononyl
adipate.
(3) Proposed classification numbers:
(i) HTSUS number: 2917.12.20.00.
(ii) Schedule B number: 2917.12.2000.
(iii) CAS number: 33703-08-1.
(4) Petition filing dates:
(i) Petition filing date for purposes of making a determination:
May 1, 2025.
(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: Di-lsoNonyl Adipate (``DINA'') is a
light colored and oily liquid plasticizer which is used in polymeric
systems based on vinyl, nitrocellulose, and rubber. In these systems,
DINA adds flexibility to products at low temperatures. Other features
would include good electrical properties, good stability to heat,
impact resistance, and good resistance to weathering.
DINA is produced using propylene, benzene, and nitric acid. Taxable
chemicals constitute 79.20 percent by weight of the materials used to
produce this substance.
(6) Process identified in petition as predominant method of
production of substance: Di-isononyl adipate is produced via
esterification. The di-isononyl adipate di-ester is made by reacting
primary isononyl (C9) alcohol with adipic acid. The ester is produced
by esterification of 2 moles of isononyl C9 alcohol and 1 mole of
Adipic Acid in the presence of a catalyst.
By using excess alcohol (up to 30% molar excess of C9 alcohol) and
removing the water, the equilibrium is shifted towards the formation of
the di-ester. The reactants are charged into a reactor and heated up.
The reaction rate is accelerated by using, for example, tetra-n-butyl
titanate introduced at high temperature (140 [deg]C-250 [deg]C), while
removing the water formed.
Excess alcohol is distilled from the ester by vacuum prior to
neutralization and recycled into subsequent batches. The final ester is
purified by neutralizing with a base such as an aqueous solution of
sodium carbonate. The remaining excess water is distilled off and the
ester is then filtered using filter agents. The degree of purity of the
ester is min 99.0 wt%.
(7) Stoichiometric material consumption equation, based on process
identified as predominant method of production:
4.82 C<INF>3</INF>H<INF>6</INF> [propylene] + 0.3
C<INF>5</INF>H<INF>10</INF> [amylene] + 2 CO [carbon monoxide] + 7
H<INF>2</INF> [hydrogen] + C<INF>6</INF>H<INF>6</INF> [benzene] + 0.5
O<INF>2</INF> [oxygen] + 2 HNO<INF>3</INF> [nitric acid] [rarr]
C<INF>24</INF>H<INF>46</INF>O<INF>4</INF> [di-isononyl adipate] + 4
H<INF>2</INF>O [water] + N<INF>2</INF>O [nitrous oxide]
(8) Tax rate calculated by Petitioner, based on Petitioner's
conversion factors for taxable chemicals used in production of
substance:
(i) Tax rate: $7.07 per ton.
(ii) Conversion factors: 0.51 for propylene, 0.20 for benzene, 0.32
for nitric acid.
(9) Public docket number: IRS-2025-0048.
