What is the product of C5H8NO4Na + KC4H5O8 ?
« on: 19/09/2014 07:35:07 »
Hello there,
Would greatly appreciate if anyone could suggest the possible reactions for the following combinations:

C5H8NO4Na + KC4H5O8  >>>>> ?

C5H8NO4Na + HCL  >>>>> ?
   
Thank you for your help.

KC4H5O8 ?  That does not appear to be conceivable chemical compound. Potassium methacrylate maybe?  Is this a polymer reaction?


C5H8NO4Na I'm assuming is monosodium glutamate?

Do you have any more information than this?

Thanks for your reply.

C5H8NO4Na is mono-sodium glutamate or MSG, as you have stated correctly.
KC4H5O8 is potassium hydrogen tartrate.

Hope you can suggest the products of MSG combined with 1) potassium hydrogen tartrate and 2) HCL,
if there are any reactions at all.

Thank you.

potassium hydrogen tartrate has the formula KC4H5O6

Under reasonable conditions in solution, HCl will react with monosodium glutamate to produce glutamic acid and sodium chloride

According to wikipedia, the natural isomer of tartaric acid has pka1= 2.89 and pka2 = 4.40; and glutamic acid has pka1 = 2.10, pka2 = 4.07. monosodium glutamate and monopotassium tartrate are each deprotonated once, so if we want to see whether there is a reaction or not we must compare pka1 of each with pka2 of the other. 2.89 < 4.07 and 2.10 < 4.40, so I would not expect an acid base reaction between the two species. Depending on what solvent and temperature were used one might be able to get monopotassium glutamate or monosodium tartrate out of the reaction mixture, but I would be surprised if there were a large driving force to these products.

Of course, whether there is a reaction, and what type of reaction there is has almost as much to do with the conditions as the reactants themselves. Boiling monosodium glutamate in concentrated HCl for a long time is likely to result in many different reaction pathways...
