Abstract

See full text

A process for the hydrogenation of hop resin acids in their naturally acidic state comprising contacting said hop resin acids with hydrogen gas in the presence of a noble metal catalyst, wherein, in order to eliminate the necessity of a subsequent removal of conventional solvents, said hop resin acids are hydrogenated by direct contact with said noble metal catalyst under an atmosphere consisting of hydrogen gas and in the absence of conventional solvents, including water and organic liquids, under conditions such that the hop resin acid/catalyst mixture is in a sufficiently fluid state for being easily and continuously mixed by agitation in an autoclave.
