Picric acid converted it to acetylsalicylic acid, i.e., aspirin, to keep it from the Allies. See Great Phenol Plot. At the time, phenol was obtained from coal as a co-product of coke ovens and the manufacture of gas for gas lighting. Laclede Gas reports being asked to expand production of phenol (and toluene) to support the war effort. Both Monsanto and Dow Chemical undertook manufacture of synthetic phenol in 1915. Dow was the leading producer. Dow describes picric acid as “the main battlefield explosive used by the French. Large amounts [of phenol] also went to Japan, where it was made into picric
Vinylphosphonic acid known for promoting adhesion between organic and inorganic phases. Such interfaces exist between coatings and the substrates to which they are applied. Both vinylphosphonic acid homopolymer and its copolymers are the basis of many products which have found applications in scale and corrosion treatment. Polyvinylphosphonic acid is an essential component for the polymer electrolyte membranes used in fuel cell development, in the medical field as dental cements, hydrogels for drug delivery, and components in biomimetic mineralization. Vinylphosphonic acid Vinylphosphonic acid is an organophosphorus compound with the formula CHPOH. It is a colorless, low-melting solid although commercial samples are often yellowish
