Abstract
Cresols are mixed with an acid and a mercury salt catalyst-in an example sulphuric acid with mercury sulphate and ferric chloride-and acetylene is passed in; the reaction product is dissolved in benzene, freed from acid and salts by washing, and distilled in vacuo; cresols and benzene distil off up to 100 DEG C., followed by a liquid product up to 200 DEG C., the residue being a resinous solid soluble in alcohol or benzene. The liquid distilling up to 200 DEG C. is converted into a tanning-agent by sulphonation.
