In which lead tetraethyl occurs In the vapor state, and at times under pressure.

I do not regard the warning on your yellow label as entirely adequate since in general chemists will have the point of view that the vapor pressure of tetraethyl lead at ordinary temperatures is so low as to be essentially negligible.

What i3 the best solution to U3 for decomposing tetraethyl lead in the small quantities in which it might be found on laboratory glassware, and on the floor of the chemi cal hood in which one works with tetraethyl lead on a laboratory scale.

Dear Cal: A few days ago I was asked a direct question in connection with the use of tetraethyl lead as an ethylating agent for an arsenic compound, a3 to the temperature at which appre ciable decomposition of tetraethyl lead begins to occur.

Tetraethyl-lead production.

(For your information I should point out that the lead concentration in the blood, following serious exposure to tetraethyl lead is usually quite low.

The handling of a solution of tetraethyl lend in oil, or other solvents* involves two definite risks which vary in msgnitud# with the concentration of the solution* namely * lead absorption though the akin m the result of contact, ami lead absorption by inhalation of vapors rising from the solution*.

In audition to these ingredients kerosene is used as a diluent just to the point which makes the proportion of tetraethyl lead constant in all of these fluids, so as to facilitate blending in gasoline to the correct level of concentration of tetraethyl lead per gallon of gasoline.

The pattern of response in the work done so far would aopesr in the case of tetramethyl lead to follow that of tetraethyl lead where it has been shown, in a paper published by Miss J.

Moreover experimental work reported to us in which BAL has been used In connection with the administration of tetraethyl lead, have given no evidence of beneficial effect.
