Abstract: The present invention concerns the use of compounds of the Formula (I) for treating different types and symptoms of acute and chronic pain, especially non neuropathic inflammatory pain in mammals. The pain to be treated may be e.g. chronic inflammatory pain, rheumatoid arthritis pain and/or secondary inflammatory osteoarthritic pain. The compounds show an antinociceptive profile and differ from classical analgesics like opioids and non-steroidal anti-inflammatory drugs (NSAIDS) and are useful as specific analgesics.

Abstract: The present invention relates to a process for the dissociation of allophanates, in which a thermal dissociation is carried out in a reaction vessel and the gaseous dissociation products obtained are removed from the reaction vessel using an inert carrier gas or the vapor of a liquid as stripping medium and are condensed.

Abstract: A process for preparing N-acyl derivatives of the formula I, in which the substituents independently of one another have the following meanings: X is CH(OR3)2, COOR3; R1 is hydrogen, C1-C12-alkyl, aryl, unsubstituted or substituted; R2 is hydrogen, C1-C12-alkyl, aryl, unsubstituted or substituted; R3 is C1-C12-alkyl, which comprises reacting a carboxamide R1—CONH2 of the formula II with a glyoxal monoacetal derivative of the formula III, in the presence of a carboxylic acid R4—COOH of the formula IV where R4=C1-C12-alkyl, where the substituents R1 to R3 are as defined above, is described.

Abstract: The present invention relates to a process for the selective preparation of 4,4-methylene-bis-(N-phenylalkylcarbamate) which comprises condensing N-phenylalkylcarbamate with a methylating agent in the presence of an acidic ion-exchange resin or an aqueous acid as a catalyst and a non polar aprotic solvent and filtrating a condensation product at a temperature greater than the melting point of N-phenylalkylcarbamate to separate 4,4-methylene-bis-(N-phenylalkylcarbamate).

Abstract: Pure acetyl chloride containing less than 1 ppm of phosphorus is produced. To this end, crude acetyl chloride containing phosphorus compounds is intimately contacted with 1 to 20 liters of gaseous chlorine per liter of liquid crude acetyl chloride and the acetyl chloride so contacted with chlorine is subjected to fractional distillation.

Abstract: Production of propionic acid and propionic anhydride with the repression of polyketone formation by carboxylating ethylene utilizing a catalyst system essentially composed of an iridium compound in the substantial absence of added halide components.
