Abstract: A process is described for preparing ammonium salts of aromatic carboxylic acids by reacting an aromatic carboxylic acid with ammonia in an aprotic solvent, which comprises carrying out the reaction in a closed vessel by continuously introducing a solution of the aromatic carboxylic acid in the aprotic solvent and passing in gaseous ammonia so that an ammonia partial pressure in the range from 0.1 to 3 bar is maintained in the gas space of the vessel, and discharging a suspension of the ammonium salt in the aprotic solvent. The process allows the preparation of ammonium salts of defined crystal size having a narrow size distribution.

Abstract: A mount assembly for use in an automotive suspension system, body mount, cradle mount, or other like device. The mount assembly includes a polyurethane elastomer carrier mounted to a frame and having a peripheral outer rim. A microcellular polyurethane insulator is coupled to the frame and extends beyond the peripheral outer rim. The polyurethane elastomer of the carrier has a first modulus of elasticity. The microcellular polyurethane of the insulator has a second modulus of elasticity that is less than the first modulus of elasticity of the carrier such that the mount assembly can provide two distinct rates of elasticity, or stiffness, for adequately isolating both low amplitude, high frequency vibrations and high amplitude, low frequency impacts.
