ASTM D – 11 Standard Test Method for Distillation Range of Volatile Organic Liquids
Boiling temperatures observed on a partial immersion thermometer are corrected to standard atmospheric pressure to give true boiling temperatures. IBP 50 75 r 0. The study involved six samples of different boiling point ranges, done in duplicate. The hole must 1d078 perfectly circular, with no irregularities.
Center the thermometer into the neck of the flask through a tight-fitting cork stopper so that the upper end of the contraction chamber or bulb if Thermometer 2C or IP thermometer 62C is used is level with the lower side of the vapor tube at its junction with the neck of the flask. The relative volatility of organic liquids can be used with other tests for identification and measurement of quality.

Preparation of Apparatus 8. D — 01 Designation: NOTE 2—Toluene is shown in reference manuals as boiling at Significance and Use 5. Therefore, this test method provides a test procedure for assessing compliance with a specification.
Summary of Test Method 4. Record the temperature and report as the decomposition point Section 3. Astn should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law. Caution should be taken when handling mercury and mercury-containing products. Any variation would result in heating a larger portion of surrounding air to a higher temperature than that of the flask.
Awtm relative volatility of organic liquids can be used with other tests for identification and measurement of quality. Adjust the position of the heat shield so that the neck of the flask is vertical and the vapor tube extends into the condenser tube a distance of 25 to 50 mm.
We need your help to maintenance this website. It is the responsibility of the user of this standard to establish aatm safety and health practices and determine the applicability of regulatory limitations prior to use.
The flask is then prepared for use by washing with water, rinsing with acetone, and drying. This can be accomplished potentiometrically by the use of standard precision resistance, depending on the type of probe. As the relative volatility, residual matter and recovery capability affect the efficiency of these processes, this test method is useful in manufacturing control.
Please help us to share our service with your friends. Specific hazard statements are given in Section 7. Please fill this form, we will try to respond as soon as possible. Have the bottom of the flask resting firmly in the hole of the heat shield. Record the readings of the distillation thermometer after collecting 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, and 95 mL of distillate.
If no thermometer is specified, select one from Table 1 with the smallest graduations that will cover the entire distillation range of the material. Size px x x x x We are a non-profit group that run this website to share documents.
Compound 6 The sole source of supply of the Lo-Cap heater known to the committee at this time is Precision Scientific Co. As the relative volatility, residual matter and recovery capability affect the efficiency of these processes, this test method is useful in manufacturing control. It was found that the precision is dependent on the boiling point temperature. Confirmation of the calibration of these temperature sensors shall be done at regular intervals.
Mercury, or its vapor, may be hazardous to health and corrosive to materials. In the operation of the distillation apparatus, use a suitable catch pan and shielding to contain spilled liquid in the event of accidental breakage of the distillation flask.
