Abstract: 3- and 4-Methyl-4-dodecenal, a method of their production and fragrance and flavor compositions comprising at least one of them.

Abstract: The invention relates to a mist eliminator system for gas scrubbers and the like. Said mist eliminator system comprises front and rear mist elimination layers in relation to the direction of the flow of gas, which layers are composed of respective rows of parallel mist elimination profiles, one layer of which being configured in the shape of a V or of an upturned V and the lateral sections of this layer extending away from the corresponding lateral sections of the other layer or extending in parallel thereto. Both mist elimination layers can be or are received on a single common carrier structure by a common lateral wall or a common supporting structure on which the lateral walls of the mist elimination layers are stationarily or detachably arranged.

Abstract: The present invention is related to 4-hepten-2-yl salicylate and its use as fragrance ingredient.
