    Abstract: THE PRODUCTION OF 2,2-DIMETHYL1,3-PROPANEDIOLHYDROXYPIVALIC MONOESTER BY HEATING 2,2-DIMETHYL-3-HYDROXYPROPANAL (PRAPARED BY THE REACTION OF FORMALDEHYDE WITH ISOBUTYRALDEHYDE IN THE PRESENCE OF TERTIARY AMINES) IN THE PRESENCE OF AN ORGANIC SALT OF A TERTIARY AMINE. AS COMPARED WITH THE PRIOR ART METHODS, THE PROCESS ACCORDING TO THE INVENTION GIVES 2,2-DIMETHYL-1,3-PROPANEDIOLHYDROXYPIVALIC MONOESTER BY A SIMPLER AND MORE ECONIMICAL METHOD, IN HIGHER PURITY AND WITH A HIGHER YIELD WITH REFERENCE TO THE STARTING MATERIAL AND WITH A HIGHER SPACE-TIME YIELD OF PURE END PRODUCT. THE COMPOUND WHICH CAN BE PREPARED BY THE PROCESS ACCORDING TO THE INVENTION IS A MORE VALUABLE STARTING MATERIAL FOR THE PRODUCTION OF SYNTHETIC RESINS AND PLASTICIZERS.

    Abstract: A process for the preparation of an aryl mono-, di-, and/or polyurethane comprising the steps of A. reacting a primary aromatic mono-, di-, and/or polyamine with an O-alkyl carbamate in the presence of an alcohol at temperatures greater than 160 DEG C., and B. separating the ammonia and other by-products from the aryl mono-, di-, and/or polyurethane. The reaction is preferably carried out in the presence of urea. The aryl mono-, di-, and/or polyurethanes produced are valuable end and intermediate products. They can be transferred into the corresponding isocyanates which can then be used for the preparation of polyurethanes.
