Talk:Allophanic acid

Synthesis reaction and the properties table

I believe that the synthesis reaction of the allophanic acid, which is provided by the source [1], is incorrect.

Based on my understanding, the product likely would be sodium allophanate rather than the free acid as NaOH formed during the reaction would react with the acid to form a salt. Additionally, the decomposition of urea in the presence of carbonates or bicarbonates often to the formation of isocyanates.

Moreover, as far as I know allophanic acid was never isolated, so how are the "Appearance" and "Melting point" fields filled? They have no source attributed to them. Based on this source: https://pubs.acs.org/doi/abs/10.1021/ja00153a022 allophanic acid and its inorganic salts easly hydrolize.

I appologize for the chaos in this comment, however I am writing in a hurry. 185.21.84.9 (talk) 15:37, 28 January 2025 (UTC)

often leads to the formation of isocyanates*

Good points. We need to see if this stuff has ever been isolated. --Smokefoot (talk) 19:58, 28 January 2025 (UTC)
