摘要: An improved process for the production of a high purity terephthalic acid by a liquid phase oxidation reaction of para-xylene by means of molecular oxygen or a molecular oxygen-containing gas in an aliphatic monocarboxylic acid solvent in the presence of a cobalt-manganese-bromine catalyst system, characterized in that as the cobalt-manganese-bromine catalyst system there is used a catalyst system of a specific composition at a specific concentration, and the liquid phase oxidation reaction is effected in the presence of acetaldehyde in addition to the cobalt-manganese-bromine catalyst system under relatively mild temperature (170.degree.-190.degree. C.) and pressure conditions while maintaining the water concentration in the reaction system at a specified low level. The terephthalic acid produced according to the process of the present invention is of so high a quality that it can be used for the direct production of a polyalkylene terephthalate from the acid and an alkylene glycol or ethylene oxide, which direct production does not need the preparation of an intermediate such as a methyl ester of terephthalic acid.

摘要: An oscillation limiting mechanism (4) is integrally provided to an engine mount (3) (a vibration proof mount device) of a power plant (P) mounted on an automobile in a traverse mount fashion. Not only is a stopper metal member (40) in the shape of an inverted U letter disposed so as to cross over a mount body portion (30), but a stopper rubber (42) is formed so that it protrudes from the rear end of a casing of the mount body portion (30) toward the rear side of the vehicle body. Not only is a hollow portion (43) formed in the interior of the stopper rubber (42), but a metal core body (44) is also embedded in the stopper rubber (42) so as to be revolvable around an axis in the vehicle body traverse direction as if it were a link. With such a construction adopted, the stopper rubber (42) is shear-deformed in the vertical direction with comparative ease even in a state where it is brought into contact with the rear side leg portion (40c) of a stopper metal member (40) and thereby receives a compressive force in the vehicle body longitudinal direction, and a dynamic spring constant of the mount (3) in the vertical direction does not rise so much even if the stopper acts in rapid acceleration or the like; therefore, enabling increase in surrounding sound in acceleration to be suppressed with a simple structure less of cost up while oscillation of the power plant (P) is limited in a similar way to that of a torque rod.
