THE CHEMICAL WORLD THIS WEEK of the metaborate of an alkali or alkaline earth metal bonded to a heat-conductive base is bombarded b y a stream of high velocity, subatomic particles. Methods of Forming Uranium Carbide. Pat. 2,580,349. Uranium monocarbide is produced by heating uranium metal in contact with methane, or an aliphatic hydrocarbon, at a temperature of 400° to 1125° C. The hydrocarbon is in such amount that the carbon content corre sponds to about 4 . 8 % by weight of the uranium metal content. Preparation of Metal Halides. Pat. 2,580,357/ This patent describes appara tus for facilitating chemical reactions be tween a vaporizable solid and a non volatile solid comprising four intercon nected chambers with associated con trolled heating means. Storing Perhaloacetyl Peroxide m and Stabilized Perhaloacetyl Peroxide. Pat. 2,580,358. This patent covers means for storage of a perhaloacetyl peroxide which comprises dissolving the peroxide immedi ately after preparation in a perhalomethane solvent, such as trichlorofluoromethane, and maintaining the resultant solution at a subzero temperature until it is put to use. Processes for Preparing Perhaloacetyl Peroxide. Pat. 2,580,373. This patent covers a method for the preparation of a perhaloacetyl peroxide, comprising dis solving either an alkali or alkaline earth metal peroxide in an aqueous brine solu tion, cooling the solution to a tempera ture between its freezing point and 0° C. and adding to the cooled solution a perhalo derivative of acetic acid while main taining the temperature of the solution in the aforementioned range. Process for Electrodepositing Uranium Dioxide. Pat. 2,581,863. Thin films of metal compounds, such as uranium oxides and hydroxides are prepared for deter mination of the radioactivity thereof by counting techniques. The thin uniform . film of metal compound is produced by electrodeposition from an alkaline solu tion. Processes of Producing Uranium Chlo rides. Pat. 2,582,941. Uranium pentachloride and hexachloride are prepared by treating uranium oxides and lower ura nium chlorides at an elevated tempera ture with a chlorinating agent comprised of a fast flowing stream of air mixed with carbon tetrachloride vapor. The gas stream carries the moderately volatile, higher valence uranium chlorides away from the heated reaction zone to a col lection zone maintained at a lower tem perature. Process for Producing Fluorocarbons. Pat. 2,585,644. This patent covers a proc ess for producing fluorocarbons contain ing a minimum of unsubstituted hydrogen' atoms from hydrocarbons of from 17 to 2 3 carbon atoms such as petroleum lubri cating oil. The petroleum oil is treated

with bismutli pentafluoride at an elevated temperature, in the range of 90° t o 450° C , either by heating a mixture of the oil and the bismuth pentafluoride, or by passing a vapor stream of the oil over a bed of the fluorinating agent. The reac tion product is subjected to suitable sepa rative procedures to obtain the highly fluorinated product. Method of Isotope Analysis. Pat. 2,585,901. This patent describes a method o f determining the isotopic composition o f an element comprising incorporating t h e element in a compound capable of e n hancing the corresponding spectral lines characteristic of the isotopes of the e l e ment, producing a spectrum of said com pound, and ascertaining therefrom t h e relative abundance of t h e isotopes of t h e element.
Electrolytic Process Available For Licensing or Sale Information has been received through the U. S. Department of Commerce that an Austrian patent application pertaining to a method for the electrolytic oxidation of chlorides to chlorates or hypochlorites is available for licensing or sale by t h e owner, I. V. Gaertner. The process employs a series of coppercoated magnetite electrodes. These e l e c trodes are covered b y lacquer to prevent corrosion and are further protected by a cushioning material such as asbestos, kieselguhr, or slagwool. Inquiries concern ing complete details of the process a n d licensing or selling arrangements should be addressed to Dr. Gaertner at A m Graben 28, Vienna I, Austria.
ments division, consists primarily of finer temperature control and more exactness in maintaining fuel and air ratio and dis tribution in a taconite pelletizing furnace. Assuring the proper ratio of fuel and air in the processing of the ore causes it to be delivered with chemical and physical characteristics that equal those of higher grade ore. The mediod also makes possible maximum fuel economy, Green said. I n the improved process iron fines and dust of taconite are fused into pieces large enough to be easily transported and b i g enough to remain in t h e blast furnaces and not be blown away b y the blast itself.
Several Factors Affect Life of a Tin Can How long will a tin can last? Scientists of the Armour Research Foundation, Illi nois Institute of Technology, have been studying the problem recently and have a few clues to ways of prolonging can life. In explaining their results, they point o u t that a tin can really isn't tin—it is a steel can coated on the inside with a thin layer of tin. This layer is eventually corroded by the food contained and the food juices are then in direct contact with t h e steel, which corrodes more rapidly than tin. Sometimes can companies use extra-heavy coats of tiru to prevent such corrosion to the base metal. One of the current foundation projects is concerned with developing a base metal which will corrode at a low rate after food juices get through the tin.
Chemical Girdling of Trees The Armstrong Forest Co., of Johnsonburg, Pa., has purchased patent rights f o r chemical girdling of trees from Alexander R. White of Port Arthur, Ont. Mr. W h i t e held these rights under U. S. Patent N o . 2,324,968. According to the purchase agreement, the company has dedicated the chemical girdling process to public use.
Improved Technique Useful For Taconite Processing An improved technique said to make it economically feasible t o process taconite, a hard stone containing 24 to 30% iron, and to increase the value of low-grade iron ore was described recently at the annual meeting of the American Institute of M i n ing and Metallurgical Engineers in N e w York. The technique, described by John R. Green, manager of t h e steel division of Minneapolis-Honeywell's Brown instru
CHEMICAL
Special apparatus for vacuum sealing cans at the National Canners Association lab Another factor in tin can use is what i s termed "pickle lag" of the steel base Λνηβη immersed in hydrochloric acid. Pickle lag is defined as the tendency of t h e metal to corrode at a very slow rate, then speed up, and finally level off at a con stant rate. Research has shown that tin cans made from steels without pickle lag have a longer shelf life.
