Parr Hydrogenators provide compact and easily operated systems for conducting hydrogenation reactions in the presence of a catalyst at pressures up to 5 atmospheres (60 psig). They are used primarily for synthesizing or modifying organic compounds by catalytic hydrogenation, reduction or condensation, but they can also be used for any other laboratory procedure in which a liquid and gas must be mixed vigorously in a glass reactor at pressures up to 5 atm.
Materials to be treated in a Parr Hydrogenator are sealed in a reaction bottle with a catalyst and connected to a hydrogen source. Air is removed either by evacuating the bottle or by flushing with hydrogen. Pressure is then applied from the reservoir and the bottle is shaken vigorously to initiate the reaction. Progress of the reaction can be followed by observing the pressure drop in the system After the reaction reaches the desired point, the shaker is stopped, the bottle vented and the product and catalyst are recovered.
Features of the Model 3911 include:
This Parr hydrogenator is in excellent condition and comes with a 60 day warranty.
