AI Thread Summary
The discussion centers on the synthesis of mono-esterified mono-phosphate salt groups from carboxylic acids, specifically focusing on the reaction between acetic acid and sodium dihydrogen phosphate. The reaction is noted to yield acetyl phosphate, with the process typically involving transesterification of an organic acetate with phosphoric acid rather than a direct reaction. While the synthesis of the compound itself is not considered particularly challenging, the complexities lie in the separation, isolation, and workup of the product, which require optimization. Participants express a desire for an optimal synthesis route but acknowledge that existing resources, such as Google, may provide sufficient information.

TL;DR Summary
Organic Chemistry
I am interested to see if anyone knows the easiest way to mono-esterify a mono-phosphate salt group to a carboxylic acid.

How to facilitate the resultant -> product ?

CH3COOH + NaH2PO4 ‐> C2H4NaO5P + H20

You can google “acetyl phosphate preparation” to get several results on how the compound is prepared commercially. Generally, it goes through a transesterification of an organic acetate with phosphoric acid, rather than a direct reaction of acetic acid with a phosphate, though the latter will probably work at least a little bit under the right conditions. The compound itself isn’t likely to be particularly difficult to make, but the separation/isolation/general workup is probably where most of the optimization of the reaction happens.
 
Thanks for the response,
Would you happen to have an optimal route to synthesis?

I’m not going to be able to do better than a google search can.
 
Thanks
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
