Abstract: Microcapsules comprise a polymeric wall material and a polymeric core material which is suitable as a leveling agent for film formation by film-forming oligomers and polymers.

Abstract: 5-Formylvaleric esters are prepared by a process which comprises the following steps:(a) Hydroformylation of a pentenoic ester by reaction with carbon monoxide and hydrogen at elevated temperatures and under superatmospheric pressure in the presence of a carbonyl complex of a metal of group 8 of the Periodic Table with formation of a mixture of 5-, 4- and 3-formylvaleric esters,(b) Isolation of the 5-formylvaleric ester from the resulting mixture of 5-, 4- and 3-formylvaleric esters, a mixture essentially consisting of 4- and 3-formylvaleric esters remaining,(c) Cleavage of the mixture essentially consisting of 4- and 3-formylvaleric esters at from 50.degree. to 400.degree. C. in the presence of a catalyst to give pentenoic esters and(d) Recycling of the pentenoic esters to stage (a).

Abstract: The invention is directed to 1-(2,6-Dimethyl-Phenyl-amino)-2-Dimethyl-amino-Propane and the pharmaceutical composition thereof useful for the treatment of cardiac rhythm disorders.

Abstract: The invention relates to fuels for Otto engines containing small proportions of the alkali-metal or alkaline-earth-metal salts of amic acids of the general formulaR.sup.1 R.sup.2 N--CO--A--COOHor of analogous partial amides of tricarboxylic or tetracarboxylic acids whose carbamoyl groups have the general formulaR.sup.1 R.sup.2 N--CO--,where A is the bivalent radical vinylene, ethylene, trimethylene, or tetramethylene and either R.sup.1 and R.sup.2 are identical or different, substituted or unsubstituted alkyls or alkenyls of from 5 to 75 carbon atoms or R.sup.1 is hydrogen and R.sup.2 is the group of the general formulaR.sup.3 R.sup.4 N--[C.sub.n H.sub.2n O].sub.x --C.sub.n H.sub.2n --,where R.sup.3 and R.sup.4 are identical or different hydrocarbon radicals of from 1 to 18--preferably from 4 to 13--carbon atoms, n is 3 or 4 (or 3 and 4), and x is from 4 to 99.
