Purifying Alcohol M an u factured by D istilling Ferm ented Sulfite Liquor. G . Ekstrom , M a y 5, 1914. U. S. P at. 1,095,830.
Fermented sulfite liquor contains besides alcohol sm all quanti
ties of more or less volatile compounds, such as sulfurous acid, aldehydes and ketones w hich follow the alcohol during the dis
tillation process and m ake the final product im pure and which also partly afTect th e m aterial of th e distilling apparatus.
The process consists in treatin g the alcohol with bases during the distillation of the sulfite liquor itself, while the alcohol and the impurities accom pan ying the sam e are in form of steam or vapor". T h e base, for instance, carbonate of sodium, is introduced directly into the distilling apparatus, or one m ay provide a separate p urifying apparatus charged w ith the basic purifying agent, through w hich the w eak alcohol vap or distilled from the sulfite liquor is led, before it is led through the other parts of the ap paratus to be concentrated and con
densed.
In the use of the apparatus illustrated the liquor to be distilled is adm itted con
tinuously through the pipe 5 and flows successively- dow nw ard through the ap
paratus and escapes through the pipe 6. On its w ay through the apparatus 1, the liquor meets steam supplied through the pipe 9, b y w hich the alcohol together w ith some im purities, such as sulfurous acid, and aldehyde compounds are driven off as vapor. T hese vapors pass upw ard through the column. D uring the passage of these vapors through that portion of th e colum n w hich is charged w ith a basic agent and w hich is situated betw een the su p p ly pipe 7 and the liquor su p p ly pipe 5, the sulfurous acid accom panying the alcohol vapors is bound b y th e basic agent, w hile other vapors, such as aldehyde-sulfurous-acid or acetaldehyde-sulfurous-acid, are decomposed so th a t the free aldehyde and sulfurous acid are formed. T h e aldehyde accom panies the alcohol vapors and may be separated from th e gases rem aining after the condensation of the concentrated alcohol, while the sulfurous acid will be bound to the sodium.
When the alcohol vapors in this manner have been freed from injurious im purities the concentration and condensation are accomplished in the usual m anner in the other parts of the plant.
Electric Furnace. A. Scott H ansen, M a y i2 , 1914. U. S. P at. 1,096,321.
T h is is a furnace w ith m agnetically spread disk shaped flames having passages for blow ing currents of air or gas from the sides of the furnace tow ard the flame disk into th e furnace chamber, the passages being so directed th at the currents, con
sidered as a whole, will assume the form of truncated cones having a common base in the plane of the flame disk.
Antim ony O xid. A. L. Stark, M ay 12, 1914. U . S. P at. 1,096,468. Powdered antim ony sulfid is ignited while in a state
°f suspension, thereby producing a m ixture of antim ony oxid
6
and sulfur dioxid. Such oxids are cooled im m ediately after they are formed, so as to prevent the form ation of antim onic oxid and the antim ony oxid is then separated from the other products of combustion.
Acetaldehyde. Erich B aum and M artin M ugdan, M a y 12, 1914. U. S. P at. 1,096,667. A cetald eh yd e is produced b y causing acetylene to react w ith a solution of sulfuric acid con
taining mercury sulfate as c ata ly st a t a tem perature a t w hich the acetaldehyde distils from the solution and a t a concentration of acid of not higher than 6 per cent.
G as P rocess and Product. W . O.
Snelling, M a y 12, 1914. U. S. P at.
1,096,797. A cetylene is dissolved under pressure in a liquefied natural gas com prising one or more paraffin hydrocarbons held under pressure in liquid form, whereby the solvent escapes w ith the acetylene and is combustible therewith.
W hite Lead. A. S. R am age, M a y 26, 1914. XI. S. P at. 1,097,672. B asic car
bonate of lead is prepared from lead sul
fate b y reacting upon it with an alkali
carbonate in less proportion than is required for the conversion of all of the sulfate into carbonate. T h e product is then treated w ith an alkali hydroxid.
Lead Salts of A cetic A cid. F. J. K alk ow , M a y 19, 1914.
XI. S. Pat. 1,097,099. In this process lead salts of acetic acid are m anufactured from lead using air as an oxid ant and either acetic acid or an aqueous solution of
normal lead acetate as solvent.
In th e practice of the process a mass of lead, 2, is supported on a grate, 3.
T h e solvent 4 is on the bottom of the vessel and the surface of the liquid is ju st below the grating 3, although the level of the liquid m ay v a ry w ithin certain limits. Through pipe 5 air under pressure is adm itted into the liquid and in rising carries liquid w ith it into the mass of lead which it sprinkles as it flows back to the bottom of the vessel. T h e compressed air leaves the vessel through a pipe provided w ith a safety valve, 6. T h e liquid m ay be
w ithdraw n through th e pipe 7. I t is preferable to em p ty the vessel of liquid b y adm itting compressed air through a pipe, 8.
H ydrogenated Oil. C. E llis, M a y 19, 1914. XI. S. P at.
x ,097,308. This com position consists of catalytically-hard ened edible cottonseed oil of lard-like consistency, free from dissolved m etal catalyst.
Sugar. A. L . M athew s, M a y 26, 1914. XI. S. P at. 1,097,724.
Sugar juices containing rela tiv ely large am ounts of glucose are purified b y m aking them alkaline w ith lim e while m aintaining them a t a tem perature not above 50° C . T h e solution is then brought to a neutral condition and heated to a higher tem pera
ture to rem ove im purities precipitated b y heat.
Cleaning M etal S urfaces. C. H . Thom pson, M a y 26, 1914.
U. S. P at. 1,098,338. T his process involves the em ploym ent of a b a th of an y suitable chlorid, sulfate or n itrate solution, passing an alternating current through this bath, separating th e elec
trodes from the articles to be treated b y perforated or porous partitions, and placing the articles in the b a th w ithout any m etallic connection w ith the electrodes.
