Process for making vinylphosphonic acid or vinylpyrophosphonic acid |
摘要 |
The disclosure relates to process for making derivatives of vinylphosphonic acid or vinylpyrophosphonic acid. To this end, a ketone is reacted with tetraphosphorus hexoxide in the presence of catalytic proportions of a proton-yielding substance. In the event of the products desired to be produced being vinylphosphonic acid derivatives, the vinylpyrophosphonic acid derivatives first obtained are hydrolyzed with an equivalent quantity of water.
