Abstract
Method for producing an iron carboxylate, whereby it becomes possible to prevent the generation of hydrogen during the production of the iron carboxylate by the reaction of a carboxylic acid with metal iron. An embodiment of the present invention is a method for producing an iron carboxylate by reacting metal iron with a carboxylic acid in a reaction solution, wherein the reaction solution contains a non-iron metal having a standard electrode potential of −2.5 to 0.1 inclusive or a metal compound containing the metal, or the reaction solution contains at least one metal selected from the group consisting of Ag, Bi and Pd or a metal compound containing the metal.
Claims16
A method for producing an iron carboxylate, the method comprising:
- reacting metal iron with at least one carboxylic acid selected from the group consisting of acrylic acid and methacrylic acid in a reaction liquid at a temperature of 110° C.-150° C.,
- wherein:
- the reaction liquid comprises a metal other than iron having a standard electrode potential of from −2.5 to 0.1, or a metal compound comprising the relevant metal;
- or
- the reaction liquid comprises at least one metal selected from the group consisting of Ag, Bi and Pd, or a metal compound comprising the relevant metal.
A method for producing an iron carboxylate, the method comprising:
- reacting a metal iron with at least one carboxylic acid selected from the group consisting of acrylic acid and methacrylic acid in a reaction liquid at a temperature of 110° C.-150° C.,
- wherein the reaction liquid comprises a Cu compound in an amount such that the amount of Cu comprised in the Cu compound is from 0.00001 moles to 5 moles relative to 1 mole of the metal iron;
- and
- the reaction liquid comprises an anion, whose protonated form has a pKa, which is a negative common logarithm of an acid dissociation constant, in water at 25° C. of 2 or less, in an amount f from 0.0001 moles to 10 moles relative to 1 mole of the metal iron.
