But to get to your main questions, let me say that, so far as tetraethyl- and tetrarnethyl-lead are concerned, we have little information, and there is little likelihood that we shall obtain much more.

Now that tetraethyl lead is being restricted, there is an increased use of benzene to obtain the necessary antik nock ratings.

A wide range of these materials are manufactured, but the most significant are the tetra alkyl lead compounds; Tetra methyl lead (TML) and tetra ethyl lead (TEL).

Lead Industry - 1970.

It is probable that domestic shortages would result which would -8- severely affect lead consuming industries such as the battery industry or the tetraethyl lead industry.

Both have been committed heav ily to the use of tetraethyl lead since it was first developed in 1921 to elimi nate engine knock.
