Abstract: This invention relates to novel compositions comprising a N-halodialkylamine as defined in the specification and an inorganic oxide. The compositions are useful as halogenating agents for phenolic compounds. The compositions have the advantage that they are milder halogenating agents than halogens or hydrogen halides.

Abstract: A composition for use after reductive activation as a catalyst for the conversion of synthesis gas to hydrocarbons having a carbon number greater than one, which composition has the formula:Ru.sub.a A.sub.b CeO.sub.xwhereinA is an alkali metal,x is a number such that the valence requirements of the other elements for oxygen is satisfied,a is greater than zero and less than 1% w/w, based on the total weight of the composition,b is in the range from zero to 10% w/w, based on the total weight of the composition, andCe and O constitute the remainder of the composition,is produced by the process comprising the steps of:(A) bringing together in solution soluble salts of the metals ruthenium and cerium and a precipitant comprising a carbonate and/or bicarbonate and/or a hydroxide of an alkali metal or ammonium under conditions whereby there is formed a precipitate comprising ruthenium and cerium in the form of compounds thermally decomposable to their oxides, and(B) recovering the precipitate obtained in step (A).

Abstract: A catalyst composition of use in the production of hydrocarbons from synthesis gas comprises the essential metals(a) at least one of iron, cobalt, nickel and ruthenium, and(b) at least one of lithium, sodium, potassium, calcium and magnesiumsupported on silicate, as described and claimed in U.S. Pat. No. 4,061,724, the metals [(A)+(b)] being present on the silicalite support in an amount in the range from 0.5 to 15% by weight. The catalyst composition may be modified by addition of the hydrogen form of a crystalline zeolite having the composition expressed as mole ratios of oxides:0.9.+-.0.2M.sub.2 /.sub.n O:W.sub.2 O.sub.3 :20 to 50 YO.sub.2 :zH.sub.2 Owherein M is at least one cation, n is the valence thereof, W is aluminum and/or gallium, Y is silicon and/or germanium and z has a value of 0 to 40, said zeolite being characterized by an XRD pattern which is substantially that of an MFI-type zeolite.
