ASTM D2001 Test Method for Depentanization of Gasoline and Naphthas
5. Apparatus
5.1 Depentanization Apparatus, as shown in Fig. 1, consisting of the following parts:
5.1.1 Distillation Column,
5.1.2 Reflux Condenser Head,
5.1.3 Light-Ends Trap,
5.1.4 Receiver, graduated, 12.5 mL, and
5.1.5 Thermometer, 10 to 79°C (50 to 175°F).
5.2 Column Packing - Two types are required:
5.2.1 Heli-Pak Column Packing, 1.27 by 2.54 by 2.54 mm (Size B, 0.050 by 0.100 by 0.100 in.).
5.2.2 Heli-Pak Column Packing, Size C, 4.4 by 4.4 m (0.090 by 0.175 by 0.175 in.), or Cannon Protruded Metal Packing, 4.0 by 4.0 mm (0.16 by 0.16 in.).
5.3 Distillation Flask, round-bottom, 100 mL, with 24/40 standard-taper female joint.
5.4 Distillation Flask Heating Mantle, Glas-Col, spherical, for 100-mL flask.
5.5 Variable Transformer, for regulating power to heating mantle.
5.6 Water Cooling Bath - If a supply of chilled water for the reflux condenser is not available, a satisfactory means for supplying chilled water can be provided by circulating tap water through coiled copper tubing immersed in an ice-water bath.
