Reference number: AP/38/2
Date: 1855
Description
Hofmann describes how, in the process of attempting to purify cuminic acid by boiling it with chromic acid, he observed that the acid experienced a progressive alteration. He states that after 24 hours, the cuminic acid is completely converted into an acid insoluble in alcohol and ether. For this substance he proposes the provisional name of insolinic acid. He presents an analysis of the acid.
Subject: Analytical chemistry
Received 20 December 1855.
Whilst the Royal Society declined to publish this paper in full, an abstract of the paper was published in volume 8 of the Proceedings of the Royal Society as 'On insolinic acid'.
