MANUFACTURE OF LEAD SALTS ACEI'IC Specification of Letters Patent.
Patented May 19, 1914.
Application filed January 18, 1913. Serial No.i'742,794.
I Be it known that I, FRIEDRICH JOHANN KALKOW, doctor of philosophy, a citizen of the German Empire, and resident of Ofienbach-on-the-Main, in the Grand Duchy of Hesse, Germany, (with the post-office address Frankfurterstrassefih) have invented new and useful Improvements in the Manufacture of Lead Salts of Acetic Acid, of whichthe following is a specification.
This invention relates to a process for the manufacture of lead salts of acetic acid from lead, using air as an oxidant and either acetic acid or an aqueous solution of normal lead acetate as solvent.
.There is afiprocess known which produces lead acetate from lead, acetic acid and air, wherein the mass of lead is kept immersed in acetic acid during the treatment with air under pressure. The complete covering of the mass with liquid, however, is an unfavorable condition for the following reason: Since lead can only be oxidized and therefore-dissolved where it is in contact with air, andsince by .covering the whole heap of lead with liquid one cuts 01f the air from the lead, only the bubbles of air rising through the liquid can 'efi'ect oxidation and dissolution. The air quickly eats for itself a passage through the lead and during the rest of theoperati on it travels through these pas- I sages without doingany further-appreciable work. in dissolving lead. Ra'p1idity of dissolution is onlyto benoted ina eshly charged apparatus where lead is present in excess; in continued operation the action sinksto practically nothing.
- According to the present inventiona rapid dissolution-T continuously obtained if the heap of lead is not covered with liquid but is provided. with only suflicient liquid to insure that the current of air blown through it. will carry up particles of liquid and thus continuously sprinkle the lead' lying. above the surface of the liquid. Under these conditions the liquid becomes saturated with basic lead acetate in a short time and so much hydrated oxid is formed on the lead that fresh solvent added after a shprt time becomes saturated in a short time.
By the present invention the liquid is conthe vessel.
verted into foam by the air under pressure In the'vessel 1 the mass of lead 2 is sup ported on a grating 3. The solvent 4 is on the bottom of the vessel and'in the construction shown the surface of the liquid is just below the grating 3, although thqlevel v ofthe liquid may vary within certain limits. Through pipe 5 air under pressure is admitted into the liquid and in rising therethrough carries liquid with it, as indicated in the drawing, into the mass of lead which it sprinkles as 1t flows backto the bottom of The compressed air leaves the vessel through a pipe provided with a safety valve 6. The liquid may be withdrawn through the pipe 7 It is preferable to empty the vessel of liquid by admitting compressed air through a pipe 8. A m'anometer 9 indicates thepressure.
What I claim is 1. The process of forming lead acetate, which consists in subjecting sub-divided metallic lead tothe action of air currents and a suitable liquid reagent carried'by said air currents in the form of spray.
2. The processof forming lead acetate, which consists in subjecting sub-divided metallic lead to the action of air currents moving upwardlythrough the mass of lead and entraining a suitable liquid reagent in said 'air currents in the form of spray.
3. The process of forming lead. acetate, which consists in confining sub-divided lead in a reaction vessel, maintaining a body -of liquid. reagent in the bottomof said vessel,
- and injecting jets of air; through said liquid reagent and the lead, whereby the lead is sprayed. with. the reagent..
In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this seventh day of January, 1913.
