Abstract: A process for manufacturing synthesis gas (16) from hydrocarbons, water, free oxygen, and a transfer gas containing steam and carbon oxides. The transfer gas is passed through a succession of essentially adiabatic catalyst beds (2, 3, 4, 5, 6, 7) and the hydrocarbons (9, 10,11) and oxygen (13, 14, 15) are alternately introduced at the input of each catalyst bed. The transfer gas may be prepared by vivid combustion of hydrocarbon or by hydrocarbon steam-reforming.

Abstract: A plant growth regulator comprising, as the active substance, one or more of N-substituted alanine derivatives of the general formula: ##STR1## wherein X represents halogen atom or trifluoromethyl, R represents hydrogen, straight chain or branched chain alkyl having 1-4 carbon atoms, alkenyl having 2-4 carbon atoms, an alkali metal atom or amine-forming residue, and n is zero or an integer of 1 or 2, with the proviso that when n is 2, X may be same or different, together with an inert carrier or diluent, in particular, an agent effective for controlling suckers of tobacco, and a process for regulating plant growth by using said plant growth regulator.
Abstract: Synthesis gas is produced by reacting a hydrocarbon feedstock with oxygen to give a hot gas containing H.sub.2 and CO, injecting into the resulting hot gas a hydrocarbon and possibly steam and/or CO.sub.2 and reacting the resulting mixture adiabatically over a steam reforming catalyst. These steps are carried out preferably in a reactor of substantially uniform cross section such as a gas turbine combustor.
Abstract: A process for the production of (1) an ether or (2) a second amine comprises reacting an activated olefin with respectively an alcohol or first amine in the presence of a catalyst which is either (a) an amidine or (b) a Lewis base and epoxide. The same catalyst may also be used to carry out the reverse reaction in which an activated olefin and an alcohol or first amine are produced from the appropriate ether or second amine.
Abstract: A process for producing peracids from lactic acid-containing solutions derived from biomass processing systems comprising: adjusting the pH of the solution to about 8-9 and removing alkaline residue fractions therefrom to form a solution comprised substantially of lower aliphatic hydroxy acids; oxidizing the solution to produce volatile lower aliphatic aldehydes; removing said aldehydes as they are generated; and converting said aldehydes to peracids.

Abstract: A commercially economical process for preparing a carboxylic acid ester from a carboxylic acid amide is disclosed. The process is very meritorious, since it produces neither ammonia nor ammonium sulfates. Rather, the process by-produces formamides which are very useful compounds as solvents. Further, formamide can easily be converted to hydrogen cyanide by dehydration. The process comprises reacting a carboxylic acid amide with a formic acid ester and/or methanol and carbon monoxide in the presence of a bicyclic amidine or tertiary amine catalyst and optionally in the co-existence of a metal carbonyl. An industrial process for preparing methyl methacrylate which is a materialization of the process shown above is described in detail referring to a figure.
Abstract: A process for preparing an alkaline metal salt of a polyethoxycarboxylic acid defined by the formulaR'(OR).sub.m (OCH.sub.2 CH.sub.2).sub.n-1 (OCH.sub.2)COOMby oxidation in the presence of a platinum or palladium catalyst, of a polyethoxy alcohol of the formulaR'(OR).sub.m (OCH.sub.2 CH.sub.2).sub.n OH,followed by reactivating the catalyst in the reaction mixture and recovering in active form the insoluble and soluble catalyst fractions. The alkaline metal salts of polyethoxycarboxylic acids thus produced are useful as surfactants, which can be employed in the recovery of oil from wells of medium and high salinity.

Abstract: It has been surprisingly discovered in accordance with the present invention that when dimethoxymethane is reacted with formaldehyde in the presence of an organic peroxide, the reaction preferentially involves an addition of the formaldehyde to the dimethoxymethane to provide a reaction product containing alkyl glycolates such as methyl glycolate and ethyl glycolate as principle products of the reaction. The alkyl glycolates are useful as raw materials for the manufacture of ethylene glycol.
