Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

Claims
We Claim:

1. A process for the co-production of aromatic
carboxylic esters and alkyl iodides which
comprises carbonylating aromatic iodides in the presence of an alkanol and a catalytic amount of a nickel catalyst under aromatic carboxylic
ester and alkyl iodide-forming conditions of temperature and pressure.

2. The process of Claim 1 wherein the aromatic
iodides are selected from diiodonaphthalene and diiodobenzenes.

3. The process of Claim 2 wherein the diiodonaphthalene is 2.6-diiodonophthalene and the diiodobenzene is 1.4-diiodobenzene.

4. The process of Claim 1 wherein the alkanol is methanol.

5. The process of Claim 1 wherein the temperature is in the range of 125 to 225°C.

6. The process of Claim 5 wherein the temperature is in the range of 150-200°C.

7. The process of Claim 1 wherein the pressure is in the range of 8.7 to 281.2 kg/cm2.

8. The process of Claim 7 wherein the pressure is in the range of 35.2 to 70.3 kg/cm2.

9. The process of Claim 1 wherein the process is carried out in the presence of an organic
co-solvent.

10. A process for the co-production of an aromatic dicarboxylic esters selected from dimethyl
benzenedicarboxylates and dimethyl naphthalenedicarboxylates and methyl iodide which comprises carbonylating a diiodobenzene or a diiodonaphthalene in the presence of methanol, an
organic co-solvent and a catalytic amount of a nickel catalyst at a temperature of 150 to 200°C and a pressure of 21.1 to 70.3 kg/cm2.

11. A process for the co-production of dimethyl 2,6- naphthalenedicarboxylate and methyl iodide which comprises carbonylating 2,6-diiodonaphthalene in the presence of methanol, an organic co-solvent and a catalytic amount of nickel at a temperature of 175°C and a pressure of 52.7 kg/cm2.

AMENDED CLAIMS
[received by the International Bureau on 19 May 1987 (19.05.87);
original claims 1-11 replaced by amended claims 1-11 (2 pages)]

Please amend this application by deleting the original
claims in their entirety and substituting therefor the
following claims:
1. A process comprising producing a mixture of
an aromatic carboxylic ester and an alkyl
iodide by carbonylating an aromatic iodide in
the presence of an alkanol and a catalytic
amount of a nickel catalyst in the range of
10 to 0.001 mole percent under aromatic
carboxylic ester and alkyl iodide forming
conditions of temperature and pressure.
2. The process of Claim 1 wherein the aromatic
iodide is selected from the group consisting
of diiodonaphthalene and diiodobenzenes.
3. The process of Claim 2 wherein the
diiodonaphthalene is 2,6-diiodonaphthalene
and the diiodobenzene is 1.4-diiodobenzene.
4. The process of Claim 1 wherein the alkanol is
methanol.

The process of Claim 1 wherein the
temperature is in the range of about 125 to
225°C.
6. The process of Claim 5 wherein the
temperature is in the range of about
150-200°C.
7. The process of Claim 1 wherein the pressure is in the range of 125 to 4.000 psig.
8. The process of Claim 7 wherein the pressure is in the range of 300 to 1.000 psig.
9. The process of Claim 1 wherein the process is carried out in the presence of an organic
co-solvent.
10. A process comprising producing a mixture of an aromatic dicarboxylic ester selected from the group consisting of dimethyl benzenedicarboxylate and dimethyl naphthalenedicarboxylate and methyl iodide by carbonylating an diiodo- aromatic compound selected from the group consisting of diiodobenzene and
diiodonaphthalene in the presence of
methanol, an organic co-solvent and a
catalytic amount of a nickel catalyst in the range of 10 to 0.001 mole percent at a
temperature of about 150 to 200°C and a
pressure of about 300 to 1,000 psig.
11. A process comprising producing a mixture of dimethyl 2,6-naphthalenedicarboxylate and
methyl iodide by carbonylating 2,6-diiodonaphthalene in the presence of methanol, an organic co-solvent and a catalytic amount of nickel in the range of 10 to 0.001 mole
percent at a temperature of about 175°C and a pressure of about 750 psig.
