Title: Production of carbonyl compounds
IPC: C07C45/28
Filed: 1965-05-19
Abstract: A process for producing carbonyl compounds comprises oxidizing an olefinic material with 2-20 C atoms, and at least one H atom attached to an unsaturated C atom, with an organic hydroperoxide, in the presence of a platinum group (i.e. Pd, Pt, Ru, Rh, Os or Ir) catalyst. The olefinic material may be straight chained or cyclic or aromatic, and may contain more than one double bond.  It may also bear additional substituents, e.g. Cl.  The products are generally ketones, exceptions being CH3CHO from CH2 = CH2, and aldehydes in general from dienes, e.g. butadiene yields crotonaldehyde. As organic hydroperoxides there may be used cumene hydroperoxide, t-butyl hydroperoxide, cyclohexyl hydroperoxide or a -phenethyl hydroperoxide. Preferred types are derived from an aralkyl hydrocarbon having at least one H atom on the C atom adjacent to the ring, e.g. cumene and ethylbenzene.  Ketone and hydroxy hydroperoxides may also be used.  The catalyst is preferably derived from Pd, and is most suitably a soluble salt thereof, e.g. chloride, nitrate or sulphate, used in an amount between 10-4-10-1 parts by weight per part of hydroperoxide. Reaction temperature is usually - 20 DEG - + 200 DEG  C. at atmospheric pressure, but pressures up to 50 At. may be used.  The reaction is preferably conducted in an acidic aqueous solution, but non-aqueous solvents may be present.

Title: Alkylating aromatic compounds
IPC: C07C2/86
Filed: 1944-11-01
Abstract: Aromatic compounds are alkylated by contacting with an alkylating agent in the presence of successive stationary portions of an alkylation catalyst in each of a series of alkylating units, the reactants being gradually introduced to exhaust successively each portion of catalyst.  A series of reactors, preferably three or more, are provided, each having a header and receiver, vented at the top and connected to a settling tower for separation and return of catalyst.  The reactors may be charged with aluminium chloride and benzene, and benzene and chlorinated kerosene in a molar ratio of 3-5 : 1 fed to the first reactor at room temperature.  The reaction mixture passes up the header, through the settler to the next reactor, the product from the last reactor being treated for recovery of the pure alkyl benzene.  When catalyst in the first reactor is exhausted, it is discarded and replaced by that in the second, and so on, the last being charged with fresh catalyst.  Alternatively, the first reactor may be isolated from the system, the fresh liquor fed to the second, and an additional reactor containing fresh catalyst inserted at the end.  After recharging, the first reactor can be added when catalyst in the second is exhausted.  As a further alternative, the exhausted catalyst can be retained to purify the feed.  In addition to metal halide complexes, catalysts specified are sulphuric acid and activated bleaching earths.  Alkylating agents include various chlorinated kerosene fractions, corresponding for example to monochlor-decanes or dodecanes, amyl chlorides, tertiary butyl, isopropyl, isononyl and tetradecyl chlorides, and lower olefines such as ethylene, which may be mixed with inert diluents. Aromatic compounds include toluene, xylene, naphthalene, diphenyl, chlordiphenyl, monochlor- and o - dichlorbenzene, and phenol, with a suitable solvent if necessary.
