Abstract: Stable, liquid, homogeneous solutions of isocyanurate-polyisocyanates containing amide and/or acylurea groups in monomeric diisocyanates and/or polyisocyanates which are free from amide, acylurea and/or isocyanurate groups, are obtained by reacting polybasic carboxylic acids with diisocyanates and/or polyisocyanates to give diisocyanates and/or polyisocyanates containing amide groups and/or acylurea groups, converting the diisocyanates and/or polyisocyanates containing amide and/or acylurea groups by trimerization and, optionally, polymerization, into isocyanurate-polyisocyanates containing amide and/or acylurea groups, and mixing the products with monomeric diisocyanates and/or polyisocyanates.

Abstract: Aromatic amines are prepared by catalytic hydrogenation of nitroaromatics on hydrogenation catalysts at 160 to 450 DEG C and pressures of 1 to 50 bar, the hydrogenation catalyst containing 0.02 to 1% by weight of halogen and/or the reaction mixture containing 0.1 to 50 ppm of a halogen-containing organic compound, relative to the nitroaromatics employed.

Abstract: Methyl formate is prepared by reaction of carbon monoxide and methanol at elevated pressure and elevated temperature in the presence of an alkali metal methoxide by A) mixing the starting substances in a mixing zone, partially allowing them to react, saturating the reaction solution with CO and B) carrying the reaction to completion in one or more subsequent reaction zones without addition of further starting compounds.

Abstract: for flame-proofing plastics Title cpds. of formula: (where R1, R2, R3, R4 = H or 1-4C alkyl and A1, A2 = 1,2-dobromoalkyl (2-8C), may be prepared pref. by bromination of the corresponding cpd. where A1, A2 = 2-8C vinyl group. Advantages are high thermal stability, does not discolour the plastic or smell, low concentration 1-4.
