Two methods have been developed to purify large batches of technical-grade carbon tetrachloride. The relatively impure carbon tetrachloride that had been purchased for use in infrared analysis of dissolved hydrocarbons proved that it could be purified. One method is spinning-band distillation, which is a special type of fractional distillation. The other method involves the use of a molecular sieve, which is a material that is formulated to have special porosity and adsorbent properties and can physically lock substances (e.g., the impurities that one seeks to remove from CCl4) into its pores.
