Definitions
- the present invention relates to a process for producing 2-amino-5-odobenzoic acid by iodination reaction of 2-aminobenzoic acid.
- 2-Amino-5-yodobenzoic acid is a useful compound as a raw material for functional chemicals in addition to pharmaceuticals and agricultural chemicals.
- 2-Amino-5-iodobenzoic acid can be produced by iodination reaction of 2-aminobenzoic acid, and a method for iodination of 2-aminobenzoic acid in an aqueous KOH solution is known (Non-Patent Document). 1).
- the yield of 2-amino-5-odobenzoic acid, which is the target product is 72.2%
- half of the charged iodine is not used for iodination of 2-aminobenzoic acid and is recovered as KI. Therefore, a process for recovering and reusing iodine is required, which complicates the process and increases the cost.
- Non-patent Document 2 a method using iodine chloride (IC1) as an iodinating agent is also disclosed (Non-patent Document 2), the crude crystals obtained after the iodination reaction are colored brownish purple. Therefore, a purification process is required. For this reason, in Non-Patent Document 2, the obtained crude crystals are reacted with concentrated ammonia water in hot water to form ammonium salts, bleached with sodium hyposulfite, and further treated with decolorizing coal. Ammonium salt was acid-poured with hydrochloric acid to give the desired 2-amino-5-odobenzoic acid in a yield of 76-84%.
- IC1 iodine chloride
- Non-Patent Document 2 requires a lot of troublesome operations for purification with a low yield of 2-amino-5-odobenzoic acid.
- Patent Document 1 biphenyl and iodine or iodide are mixed with solvent, hydrogen peroxide, sulfuric acid. A process for producing iodinated biphenyl by reacting in the presence of is described.
- Non-Patent Document 1 Carl J. Klemme and James H. Hunter, J. Org. Chem., 5, 227-234, 1940
- Non-Patent Document 2 V. H. Wallingfold, Paul A. Kruege, Org. Syn., Vol. 2, 34 9, 1943
- Non-Patent Document 3 Otto Grothe, J. Prakt. Chem., ⁇ 2>, 326, 1878
- Patent Document 1 JP-A 63-91336
- the object of the present invention has been made in view of the above-described problems in the prior art, and does not require a purification step of 2-amino-5-odobenzoic acid and a recovery step of iodine.
- the aim is to provide an economically advantageous way to obtain quality 2-amino-5-odobenzoic acid.
- the present invention provides the following method for producing 2-amino-5-dodobenzoic acid by iodination of 2-aminobenzoic acid.
- a process for producing 2-amino-5-benzoic acid comprising reacting 2-aminobenzoic acid (A) and molecular iodine (B) in the presence of an oxidizing agent in a liquid phase.
- 2-aminobenzoic acid (A) and molecular iodine (B) are reacted in a liquid phase, and a solvent used for the reaction is one that dissolves 2-aminobenzoic acid.
- a solvent used for the reaction is one that dissolves 2-aminobenzoic acid.
- the use of acetic acid is particularly preferable.
- acetic acid When acetic acid is used as a solvent, it may be used alone or may contain water.
- the mixing ratio should be such that the substrate 2-aminobenzoic acid is sufficiently dissolved, and the amount of water contained in the solvent is 4 parts by weight or less per 1 part by weight of acetic acid. Is desirable.
- the amount of acetic acid used is suitably in the range of 5 to 30 parts by weight with respect to 1 part by weight of 2-aminobenzoic acid.
- hydrogen peroxide (C) is preferably used, and hydrogen peroxide water is usually used.
- concentration needs to be as high as 60% or more, and it can be 30 to 60%, which is usually handled industrially.
- the molar ratio ([C] Z [B]) of hydrogen peroxide (C) used relative to molecular iodine (B) is preferably in the range of 1 to 4, more preferably 2 to 3. When the molar ratio is 1 or more, a sufficient reaction rate and yield can be obtained, and when it is 4 or less, the decrease in selectivity due to side reactions is suppressed.
- Hydrogen peroxide may be added to the reaction system in the initial reaction force or may be added sequentially with the progress of the reaction, but it is more preferable to add it sequentially from the viewpoint of reaction efficiency.
- Perchlorates such as perchloric acid, sodium perchlorate, and potassium perchlorate, periodates such as periodic acid, sodium periodate, potassium periodate, sodium persulfate, etc. It may be used in combination with an oxidizing agent other than hydrogen peroxide such as persulfates as long as the object of the present invention is not impaired.
- the molecular iodine (B) used in the present invention may be used in an amount of about 0.3 to 0.7 times mole of 2-aminobenzoic acid (A), and about 0.5 times mole. preferable.
- the mole ratio of molecular iodine used ([B] Z [A]) is 0.3 or more, a high conversion rate of 2-aminobenzoic acid can be obtained, resulting in high productivity. Since there is no unreacted 2-aminobenzoic acid remaining, purification of the resulting 2-amino-5-odobenzoic acid becomes unnecessary.
- the target 2-amino-5-odobenzoic acid is further iodinated to give a high boiling point.
- Molecular iodine may be added to the reaction system in its entirety from the beginning of the reaction, or may be added sequentially as the reaction proceeds. Molecular iodine does not need to be completely dissolved from the beginning of the reaction.
- the reaction temperature is in the range of room temperature to the reflux temperature of the solvent (acetic acid), room temperature to 50 ° C is preferable.
- the reaction time varies depending on the reaction scale and reaction temperature, but a range of 1 to 5 hours is appropriate.
- the selectivity of the target 2-amino-5-dodobenzoic acid can be increased, so that only the product is precipitated by adding water to the product solution after the iodination reaction.
- High purity 2-amino-5-dodobenzoic acid can be obtained in high yield.
- the amount of water to be added depends on the charged concentration of the substrate, but usually a range of 5 parts by weight or less per 1 part by weight of the reaction product solution is appropriate.
- the precipitated crystals can be collected by filtration. In order to further increase the purity of the obtained 2-amino-5-dodobenzoic acid crystals, it can be recrystallized with acetic acid or methanol.
- the conversion rate of raw material 2 amino-5-dodobenzoic acid, selectivity of 2-amino-5-dodobenzoic acid, yield, and purity of 2-amino-5-dodobenzoic acid in the crystals are the recovered crystals and mother liquor, or The product liquid was measured by high performance liquid chromatography analysis.
- the selectivity “5-oodo” indicates 2-amino-5-hodobenzoic acid
- “3-oodo” indicates 2-amino-3-hodobenzoic acid.
- the isolated yield is the yield of the desired product (2-amino-5-benzoic acid: D) in the recovered crystals against the starting material 2-aminobenzoic acid (A) and iodine atom (molecular iodine (B) X 2) [( D / A), (DZ2B)].
- 2-aminobenzoic acid and molecular iodine are reacted in the presence of an oxidizing agent.
