Shaker Type Hydrogenation Apparatus SPECIFICATIONS Series Number: 3911 - Base Model 3916 - w/Heater & Temperature Controller Bottle Sizes: Standard, Air, or Explosion Proof arr Shaker Type Hydrogenators provide compact and easily operated systems for treating chemicals with hydrogen in the presence of a catalyst at pressures up to 60 psig and temperatures to 80 °C. They are used primarily for synthesizing or modifying organic compounds by catalytic hydrogenation, reduction or condensation, but they are equally suitable for any other laboratory procedure in which a liquid and gas must be...

Materials to be treated in a Parr Hydrogenator are sealed in a reaction bottle with a catalyst and connected to a hydrogen reservoir. 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. The bottle can be heated or cooled during this process, if necessary. After the reaction reaches the desired point, the shaker is stopped, the bottle vented, and the product and catalyst are recovered. Progress of the reaction can be followed by observing the pressure drop in the...

More than five hundred literature references are cited in Augustine’s book on Catalytic Hydrogenation that is listed below. Additional references can be obtained from other books in this list....

with hydrogen. All of these valves have stainless stems, PTFE packing and replaceable PCTFE seats to ensure positive, leak-proof control in quantitative procedures. A smaller, one-liter stainless tank (A16CA2) is available for semimicro operations in which small amounts of gas must be measured. The regular valves are easily transferred to this smaller tank. A six-foot pressure hose is furnished with each apparatus for filling the hydrogen tank from a commercial gas cylinder. This can be attached easily to any gas pressure regulator or tank valve system. Pressure Tested Bottles Reaction...

Shaker Type Hydrogenation Apparatus he standard 500 mL bottle (66CA) for the 3910 Series Apparatus are made with a heavy wall and a rounded bottom, which reduces its actual capacity to about 470 mL. This bottle fits tightly inside a wrap around metal screen that will restrain flying glass in case of accidental breakage. Smaller charges can be treated in an alternate 250 mL bottle (66CA2) which fits into the same bottle holder but requires an additional spacer spool to compensate for the differences in bottle heights. Special bottles with smaller capacities down to 50 mL or less can be...

A450EEB Heating Mantle A451EEB Heating Mantle All catalysts must be handled cautiously because of their highly reactive nature. Although virgin metal catalysts are generally safe themselves, care must be taken when they are brought into contact with organic liquids or combustible vapors in the presence of oxygen because of their ability to promote rapid oxidation. Any catalyst that has been exposed to hydrogen is also potentially hazardous and may ignite spontaneously as it dries. For this reason, used catalysts must always be kept wetted and out of contact with combustible vapors or...

Shaker Type Hydrogenation Apparatus 4833 Automatic Temperature Controller Temperature Measurement and Control emperature measurement and automatic bottle temperature control can be added to any Series 3900 Shaker Type Hydrogenator with a Parr 4833 Temperature Controller. This compact, microprocessor-based controller will measure and control the bottle temperature in the 25 – 80 °C range without a large investment in automatic control equipment, while providing several features usually available only in more expensive temperature control systems. The 4833 Controller operates with a Type J...

Thermocouple Assemblies Assembly No. Fits Bottle Size, mL Water Cooling Jacket Cooling can be provided for the standard 500 mL bottle in the Series 3910 Hydrogenator by adding an A103CA water jacket. This jacket fits into the bottle clamp in place of the bottle guard, using a soft rubber ring to seal the neck of the bottle. Nipples are provided for hose connections to a cold water line and to a drain. This jacket is made only for the 500 mL bottle. It is not offered in other sizes. Certification Models 3911 and 3921 Parr Hydrogenators including those with optional explosion proof motors,...

Shaker Apparatus Ordering Guides When ordering, specify any of the following: Parr Hydrogenation Apparatus, 500 mL 3911EA with Standard Motor, 115V 60Hz 3911EF with Standard Motor, 230V 50Hz 3911EG with Explosion Proof Motor, 115V 60Hz 3911EK with Explosion Proof Motor, 230V 50Hz 3911EY with Air Motor ORDERING GUIDE he 3910 Series Apparatus can be ordered under either of two catalog numbers. Model 3911 identifies the basic apparatus without a heating mantle and without a temperature controller. Model 3916 is the same as Model 3911 except a heating mantle and a 4833 Temperature Controller...
