Abstract: A process for the manufacture of salts of alkanedicarboxylic acids of 4 to 12 carbon atoms and alkanediamines of 3 to 14 carbon atoms, comprising reacting esters of alkanols of 1 to 4 carbon atoms and alkanedicarboxylic acids of 4 to 12 carbon atoms with alkanediamines of 3 to 14 carbon atoms in stoichiometric amounts in the presence of water at an elevated temperature, with continuous removal of the alkanols formed, in which process the reaction is carried out, from the start, in the presence of the particular salt of alkanedicarboxylic acid and alkanediamine which is to be manufactured.

Abstract: Methacrylic acid and butyrolactone are manufactured by hydroformylation of allyl esters of lower carboxylic acids in the presence of rhodium catalysts and inert organic solvents, followed by oxidation of the resulting formyl compounds with molecular oxygen (e.g. with air) in the presence of lower fatty acids, without prior removal of the rhodium catalysts, and elimination of the carboxylic acid from the acyloxybutyric acids formed, at from 150 DEG to 500 DEG C, using catalysts such as aluminum oxide, silicates or active charcoal.

Abstract: System for the underground gasification of coal in situ is based on producing the energy requiref for the gasifying reaction in the form of microwaves by a high-frequency generator on the surface. This energy is transmitted to the coal seam through at least one waveguide for a conversion of the electromagnetic energy of the microwaves into heat energy. System requires no air or oxygen for the reaction so that water can be used as the gasification medium and no carbon dioxide is developed by the reaction.

Abstract: In the removal and opt. recovery of O2 from gas by treatment with phosphine complexes with Mn (II) halides, the gas, if moist, is predried. Drying prevents an irreversible change, so that the complex retains a large fraction of its activity and can be used for continuous exchange. The complexes are useful for sepg. O2 from air in confined spaces, e.g. ships and aircraft, for removing traces of O2 from gases and esp. as detectors for the O2 content of gases, since they are intensely coloured when combined with O2 and colourless to pale yellow when free from O2. In an example, air was passed into 10 g 9 wt.% soln. of the dimethylphenylphosphine-Mn (II) bromide complex in THF at 20 deg.C and normal pressure. The soln. was yellowish initially and became intensely coloured very rapidly. If 2 ml water were added, the colour disappeared immediately and the O2 binding complex was destroyed. If O2 was introduced again, it was no longer bound. If 60 ml BuOH were added, the complex was destroyed within 15 min.

Abstract: The process for collecting and long-term storage of solar energy in water, uses two separate zones, positioned above each other. Solar energy is gathered in the base or in the lower water layer by absorption, the water being heated. The lower water layer is separated from the upper one by a light-permeable foil or plate. The upper water layer is thickened by natural or synthetic polymers, for thermal light-permeable insulation of the lower layer upwards. Absorption in the lower layer is improved by using a black foil at its base, or by dying the water.
