Description

7 UNITED STATES a Patented September 22, 19 03.
PAT NT OFF- on. A
PROCESS OF PRODUCING SODIUM PEROXID.
SPECIFICATION formingpart of Letters Patent N 0. 739,375, dated September 22, 1903. Application filed December 12, 1902. Serial No. 134,988. (No specimens.)
United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improve-v ments in Processes of Producing Sodium Peroxid, of which the following is a specification.
This process is intended for the rapid and complete conversion of sodium into its per-v oxid.
The process is distinguished from those heretofore proposed or in commercial use by the fact that the metallic sodium is maintainedinafiuid-that is,a liquidor gaseouscondition and by the thorough admixture of the fluid sodium and oxidizing agent, which is usually air.
The generic process may be carried out in two specifically different ways, as follows:
First. The sodium is melted and a stream or streams of air are blown through it from a pipe or finely-perforated nozzle. Instead of air, oxygen,steam, or other gaseous or solid oxidizing agent may be injected or distributed through the body of molten sodium.
Second. The sodium is heated to a temperature sufficient to vaporize it, and the sodium vapor is thoroughly intermingled with air or other oxidizing agent. The sodium is thus oxidized with great .rapidity and its peroxid precipitates to the bottom of the chamber in which the reaction is efiected.
It will be seen that this process is a much quicker and more economical one than that in common use, in which lumps of solid so-' dium are heated and a current of air is passed in contact with their surface only.
In practicing our process an excess of oxidizing agent is necessaril em loyed, since otherwise the whdlefwd ibm'ill'not be converted to peroxidomThe a fbT-bther oxidizing agent is preferably carefuIIy'd'r-i'ed before beijifgbrought into the-presence ot the sodium.
We claim- 1. The process of producing sodium peroxid, which consists in bringing sodium into a fluid condition and intermingling an oxiw dizin'g agent therewith in excess, as set forth.
2. The process of' producing sodium peroxid, which consistsin bringing sodium into a fluid condition and intermingling a gaseous oxidizing agent therewith in excess, as set forth.
3. The process of producing sodium peroxid, which consists in bringing sodium into a fluid condition and intermingling air therewith in excess, as set forth.
In testimony whereof we affix our signatures in presence of two witnesses.
