Product Line Preface Scope These instructions describe the installation, operation and maintenance of Parr 3911 or 3921 Hydrogenators offered with bottle sizes of 250, 500, 1000, 1700, 2000 or 2250 mL. They cover the basic steps to be followed when installing these reactors and describe the function of all standard components. They are intended to be used in conjunction with several related instruction sheets listed below.
Hydrogenation Apparatus Explanation of Symbols I On Position O Off Position This CAUTION symbol may be present on the Product Instrumentation and literature. If present on the product, the user must consult the appropriate part of the accompanying product literature for more information. This CAUTION symbol indicates that the surface may be hot. Protective Earth (PE) terminal. Provided for connection of the protective earth (green or green/yellow) supply system conductor.
Hydrogenation Apparatus Intended Usage This apparatus has been designed, built, and tested to strict physical and electrical standards. However, it is the user’s responsibility to install and operate it in conformance with local pressure and electrical codes. If this equipment is used in a manner beyond its intended usage, the protection provided by the equipment may be impaired.
Hydrogenation Apparatus Assembly Instructions Rinse or blow air through the hydrogen tank to remove any dust or foreign material. Likewise, blow out the gas hose and valves to be sure that they are dust-free and clean. Set the apparatus on a sturdy bench or table where there is convenient access to an electrical outlet with the appropriate supply voltage and current ratings in accordance with national and local electrical code requirements.
Hydrogenation Apparatus Operating Procedure Samples to be treated in a Parr hydrogenator are placed in a reaction bottle with a catalyst and clamped in a shaking mechanism. A gas connection is made to the bottle from a multiple valve and all air is removed either by evacuation or by flushing with hydrogen. Hydrogen is then introduced from a 4-liter reservoir while the bottle is shaken vigorously to initiate the reaction. Heating or cooling can be applied, if necessary.
Hydrogenation Apparatus Gas Tank and Valve System Pressure Limits The use of glass bottles in these reactors introduces certain pressure limitations and a potential hazard which the user must understand. Although each bottle is pressure tested before it is sold, the physical characteristics of glass are such that it is impossible to guarantee these bottles against breakage or to predict their service life.
Hydrogenation Apparatus air. If breakage or spills occur, flush the contaminated area immediately with large volumes of water and keep the area wet until all traces of catalyst have been removed. Vacuum filtration through a paper filter can be dangerous if air is drawn through the filter in the presence of a catalyst. To reduce this hazard, keep the paper covered with solution while it is under suction, or use a filter made of a non-flammable material.
Hydrogenation Apparatus Temperature Measurement and Control 4833 Temperature Controller Reaction temperatures can be measured and controlled with a Parr 4833 Temperature Controller which operates with an A295E, Type J (iron-constantan) thermocouple installed in the reaction bottle. The thermocouple is sealed in an 1/8” diameter stainless steel sheath and held in an A159CA bottle connector assembly which carries both the probe and the gas passage through a single opening in the bottle stopper.
Hydrogenation Apparatus Semi-micro Operations Small samples can be treated in a 3911 Hydrogenator by replacing the standard 500 mL bottle with a smaller 250 mL bottle (66CA2). This requires a 101CA2 spacer to compensate for the difference in bottle heights. To install the 250 mL bottle, remove the stopper and the 61CA4 washer from the gas inlet tube and slide the 101CA2 spacer onto the tube, then clamp the bottle and spacer in the holder in the usual manner.
Hydrogenation Apparatus Special Instructions for the 3921 Hydrogenator Customer installed location of Blue Plastic Vent Plug All instructions given in the preceding sections of this Manual apply equally to both the 3911 and 3921 Hydrogenators. Both models use the same hydrogen tank and valves, but the 3921 apparatus has a larger and heavier bottle clamp and shaker mechanism to accommodate larger reaction bottles.
Hydrogenation Apparatus Alternate 1000 and 2000 mL reaction bottles with a fiberglass covering (71CA2 and 72CA3) can be furnished for the 3921 Hydrogenator. These coated bottles are no stronger than the plain bottles, but the fiberglass envelope will usually retain any broken glass and prevent the loss of valuable reactants in case of accidental breakage. The maximum working pressures mentioned above applies to both plain and coated bottles alike. Both styles use the same connecting tube and fittings.
Hydrogenation Apparatus Bottle Heater References The 71CA one liter bottle, 72CA two liter bottle and the A129CA3 stainless bottle assembly may be heated in the 3921 Hydrogenator by wrapping a glass fabric heating mantle (A451E) around the bottle. No special fittings are needed for attaching this heater. Simply wrap the mantle tightly around the bottle and run the connecting cord through the slot in the top housing.
