I was wondering about the role of sodium oleate in synthesis of iron oleate, are there any alternatives?
And if we want to make iron linoleate for example, should we use sodium linolate or direct linoleic acid. Can someone suggest some papers regarding this.
Oleic acid is not soluble well in the water, therefore, by using sodium oleate, it can be dissolved and reacts easily with iron salt to form iron oleate.
Similar case with the linoleic acid, sodium linoleate is better than the linoleic acid.
Sodium salt is soluble and easy to come by (read as cheap). Potassium can work as well. Cesium probably too, but it's no better and more expensive. Calcium, magnesium and aluminium salts won't be soluble. Ammonium salt will hydrolyze. Organic amine salts- not sure, but they can act as ligands and then your product might not form.
From physical property standpoint, I think it's the the solubility, I suspect Sodium Linoleate is more soluble than, say, calcium linoleate, or other alkali earth /2A group
How about other Alkali metals and other elements?
this comes down to availability, I can't get the data, so Lithium and kalium/potassium linoleate may have better solubility, but their availability is so much less than sodium, which means they are harder to get and more expensive.
Dear Nadal,
Examples of oleates to be used in the context of iron oleate prepartion are sodium oleate, potassium oleate, lithium oleate, rubidium oleate, caesium oleate. Furthermore any other salt of oleic acid may be used.
Dear Nadal Ashi
Have a nice day.
