N. .L, assignors to E. 1.
Company, Wilmington,
Del., a corporation of Delaware No Drawing. Original application August 17,
1928, Serial No. 300,370. Divided andthis application October 3 Claims.
This invention relates to compositions of matter for use in the manufacture of tetraethyl lead and more particularly to a new composition of matter of lead and sodium containing an activating metal chloride.
This application is a division of our copending application Serial No. 300,370, filed August 17, 1928.
Thesuccessful production of tetraethyl lead 10 by the'interaction of lead mono-sodium alloy with ethyl-chloride depends upon the speed with which the reaction can be started and maintained at relatively low temperatures. It has been the practice to treat lead mono-sodium alloy with ethyl chloride under pressure, at temperatures varying between and 100 C. By this procedure it has been possible to obtain yields of 80% of the theoretical. V
Wehave now discovered that if very small amounts of certain inorganic salts, such as chlorides of aluminum or iron, are added to the lead sodium alloy, either during its formation or by remelting the already formed alloy and incorporating therewith the desired compound, the al- 5 loy is activated and higher yields of tetraethyl lead may be obtained when this new composition of matter issubjected to the reaction conditions ordinarily employed in the manufacture of tetraethyl lead from lead sodium alloy and ethyl chloride.
- The following example indicates by way of illustration one embodiment of our invention:
10 grams of sodium, 90 grams of lead and 0.01 gram of aluminum chloride are placed together in a suitable vessel and heated until the whole mass becomes liquid. The liquid mass is then agitated in any manner desired to secure thorough mixing and is subsequently cooled. The cold composition of matter is then reduced to a powder and is placed in areaction vessel capable of withstanding pressure. of fineness oi the powder is not an essentialiea- (Althoughthe degree 22, 1929. Serial No. 401,621
ture, we prefer to employ a coarse'powder for this purpose.) The composition of matter is then treated with ethyl chloride under pressure at temperatures varying between 35 and 90 C.
It will be understood that the conditions of pressure and temperature may vary as is usual in the known processes of manufacturing tetraethyl lead and for this reason the details of the usual reaction conditions, and of the recovery of tetraethyl lead from the reaction mass, are not given because they are unessential' here. Our'improvement lies in the presence of a metal chloride in the alloy, irrespective of the particular conditions employed for the production or tetraethyl lead using ethyl chloride. 'It will be apparent that other embodiments of this invention exist and may be practiced with out departing from the-spirit thereof, and it is understoodthat we do not limit ourselves to the foregoing example or description except as indicated in the following patent claims.
We claim:
1. A new composition of matter for use in the production of alkyl lead compounds which comprises the product obtained by melting together substantially 10 parts sodium, 90 parts lead and 001 part of one of the members of the group consisting of aluminum chlorideand ferric chloride.
2. A new composition of matter for use in the production of alkyl lead compound which comprises the product obtained by melting together substantially 10 parts sodium, 90 parts lead, and
.01 part aluminum chloride.
3. A composition of matter for use in the production of alkyl lead compounds which comprises the product obtained by melting together substantially 10 parts sodium, 90 parts lead, and 0.01 part ferric chloride.
