Why is tert butyl chloride finally washed with water
Tert-butyl chloride is a common organic compound used in various chemical reactions. Washing it with water is a common step in the purification process to remove impurities and residual reagents. Water is a polar solvent that can effectively dissolve many water-soluble impurities. The process of washing tert-butyl chloride with water involves the following steps:
1. Pour the tert-butyl chloride into a separation funnel or a container suitable for handling organic solvents.
2. Add an equal volume of water to the container. The water should be added slowly to avoid generating excessive heat or a sudden reaction.
3. Gently shake or swirl the mixture so that the water and tert-butyl chloride can mix and come in contact with the impurities present in the organic layer.
4. Allow the mixture to settle and separate into two layers. The water layer, containing the dissolved impurities, will be at the bottom, while the tert-butyl chloride layer will be on top.
5. Carefully drain the water layer from the bottom of the separation funnel or container.
6. Repeat the washing process multiple times, if needed, to ensure maximum purification. Each time, add fresh water, shake, and separate the layers.
7. After the final wash, drain off any excess water from the organic layer. The purified tert-butyl chloride can now be used in further reactions or stored appropriately.
Overall, washing tert-butyl chloride with water helps remove water-soluble impurities that may be present as by-products of its synthesis or as contaminants during handling or storage.
