Commercialization of tetraethyl lead a.

At the time the use of tetraethyl lead in gasoline to prevent detonation during the combustion process in automotive engines was still in the developmental stage, Webb expanded the research department, initiated by Thomas Midgley, Jr. in 1924, to engage in broad research into the performance of automotive and aeronautical engines, and into many other related mechanical and chemical problems.

As to your general remarks on our actions, it is a fact, as you point out, that I have personally made a definite attempt to direct to your attention matters relating to the manufacture of tetraethyl lead in connection with all activities of the Manufacturing Department for which I am responsible.

When leading or discharging acrylonitrile, methyl acrylate, methyl methacrylate, ethylepe oxide, propylene oxide, i vinyl chloridie, vinylidene chloride, and vinyl acetate the steam heating lines shall be blanked off leading into the tank containing these products.
