Abstract: A catalyst having the structural formula ##STR1## wherein R is 0 or an alkyl having from 1 to 10 carbon atoms and wherein P is a polystyrene polymer backbone, where the 6-member ring is part of the polymer. The catalyst is useful for converting olefins to aldehydes in high yield under reaction temperatures of from about 90.degree. to 140.degree. C. and pressures of about 300 to about 5000 psig in the presence of hydrogen and carbon monoxide yielding gases, and preferably polymer swelling solvents such as benzene, THF and toluene. The catalyst is also useful in hydrogenation reactions.
Abstract: A method for adsorbing VCM from vapors through the use of incompletely dried activated carbon under essentially adiabatic conditions allowing most of the VCM to adsorb on carbon having water previously adsorbed, the heat of adsorption of VCM desorbing the water instead of heating the carbon bed. The VCM adsorption is greater than that found on a dry bed when an adiabatic temperature rise is allowed to occur on the dry bed. A portion of the carbon bed can be kept dry if necessary to reach desired VCM levels. The advantage of the invention resides in adsorbing greater amounts of VCM per pound of carbon used, less drying necessary after regeneration, and less likelihood of high temperature deleterious reactions occurring.

Abstract: Preparation of 4-n-hexylresorcinol is achieved by a two-step process involving: first preparing hexyl resorcyl ethers by reacting resorcinol with a hexylating agent having the general formula 1-C.sub.6 H.sub.13 X in the presence of a base, and second, treating the reaction product obtained with a catalyst to yield 4-n-hexylresorcinol by a rearrangement process. X can be selected from the group consisting of Cl- Br-, I-, ArSO.sub.3.sup.-, and similar materials.
