What is meant by Absolute alcohol?

Solution

Absolute alcohol: This is ethyl alcohol of about 100 percent purity. It is made from rectified spirit by keeping it for a few days with quick lime.
Later on, it is distilled to get absolute alcohol (about 99% pure).
Alternatively, the rectified spirit is mixed with benzene and distilled when a ternary mixture of water, benzene and alcohol distils over. When all the water distils out then a binary mixture of benzene and alcohol distils at a slightly higher temperature. After all the excess of benzene distils over, then absolute alcohol distils over.
