Determination of Distillation Range of Volatile Organic Liquids (CAT#: STEM-PPA-0153-YJL)

Introduction

Organic liquids are used in a wide variety of industrial applications. They can be characterized as liquids that consist of one or more carbon atoms joined to other atoms via covalent bonds. Common atoms included in organic molecules are hydrogen, oxygen, nitrogen, sulfur, and halogens. Both the rate and yield of certain reactions have been found to greatly increase when performed in organic liquids. Thus, they are widely used in the chemical process industry for synthesis. Organic liquids include hydrocarbons, oxygenates, chemical intermediates and blends thereof.

Principle

The boiling or distilling range of a liquid is the temperature interval,corrected for a pressure of 101.3 kPa within which the liquid,or a specified fraction of the liquid,distills under the conditions specified in the test. The lowerlimit of the range is the temperature indicated by the thermometer when the first drop of condensate leaves the tip of the condenser, and the upper limit is the temperature at which the last drop evaporates from the lowest point in the distillation flask; it may also be the temperature observed when the proportion specified in the individual monograph has been collected.

Applications

Pharmaceutical industry; Petroleum industry

Procedure

1. Install the device and add the sample
