ABSTRACT:
A method of preparing tetramethyllead utilizing a novel catalyst consisting of methanol and diglyme with or without anthracene is described. The catalyst is used in quantities of at least 0.02 moles of methanol and diglyme per mole of sodium-lead alloy employed. Catalyst compositions, one comprising 2.55 to 68.28 weight per cent methanol, 5.22 to 92.72 per cent diglyme and 3.56 to 77.08 per cent anthracene and a second one comprising 30 to 10 per cent methanol and 70 to 90 per cent diglyme basis the mixture, are claimed.
