PACKAGING or BENZENE HEXACHLORIDE Loyd 'W. Piester, New Martinsville, W. Va, assignor to 'Columbia-Southern Chemical (Iorporation, Allegheny County, 2a., a corporation of Delaware 'No Drawing. Application February 24, 1956,

7 Claims. (Cl. zen-s4 he present invention relates to the handling of benzene hexachloride and more particularly is concerned with the packaging ofbenzene hexachloride in paper bags.
The gamma isomer of benzene hexachloride IS a well it is .preparedgin admixture with four other benzene hexachloride isomers by additive chlorination of benzene. These 150- mers and mixtures thereof are solid at normal temperatures. In a good many applications, the insecticidal properties of the gamma isomer of benzene hexachloride are utilized by compounding formulations of the gamma isomer and carriers. The carriers may take the form of inert solids, or may be organic solvents. To prepare formulations of this character, the benzene hexachloride is Conveniently supplied as small solid particles.
One such form of solid, particulate benzene hexachloride, is known as flaked benzene hexachloride. This is a product prepared by soldifying molten benzene hexachloride on the periphery of a rotating, cooled drum and shaving off the thin film of solidified benzene hexachloride formed on the drums periphery. The shaved benzene hexachloride is in the form of rather small thin particles, e. g. flakes.
Storage, shipment and handling of particulate, solid benzene hexachloride such as flaked benzene hexachloride has heretofore been complicated with difficulties. One economically suitable possibility packages say 50 to 100 pounds of benzene hexachloride in individual bags. However attempts made heretofore to bag benzene hexachloride in this manner and store it for extended periods have met with certain shortcomings. The bags have ruptured all too rapidly, usually within two months of Since the bagging of benzene hexachloride otherwiseoifers many advantages including ease of handling, convenience of storage, etc., bagging of solid, particulate benzene hexachloride without encountering bag failure offers considerable incentive.
According to the present invention, the discovery has been made'that benzene hexachloride may be packaged in bags, especially pap er bags, and stored therein for extended time periods ranging upwards of nine months. This extended bag life is accomplished by including in the benzene hexachloride composition a minor quantity of a solid, finely divided, inorganic alkaline material such The presence of from 0.3 to 5 percent by weight of the solidino-rganic alkaline material inhibits or substantially minimizes the tendency of benzene hexachloridecompositions to attack paper bags and cause their failure.
In this connection, it is important that the concentration of solid, inorganic alkaline material be restricted to between 0.2 and 5 percent by weight of the benzene hexachloride, and more preferably be limited to from 0.5 to 1.5 percent by weight of the benzene hexachloride. It is within these concentrations that excellent protection against bag failure is most efficiently achieved. Benzene hexachloride containing the aforementioned minor contached benzene. hexachloride is flaked.

centrations of solid, inorganic alkaline material maybe packaged andstored in paper bags for ,six months, or even longer. Rupture or other disintegration of the paper bags is obviated. Additionally, the benzene hexachloride is not unduly contaminated or diluted with components which might be undesirable.
The exact manner in which the solid, inorganic alkaline material is incorporated with the benzene hexachloride in the specified concentration can be varied to suit other considerations encountered in the manufacture of the benzene hexachloride. Especially suitable results are obtained by blending the inorganic alkaline material into molten benzene hexachloride. In conjunction with normal manufacturing procedures, this conveniently includes adding the inorganic alkaline solid to benzene hexachloride while it is in molten state during its manufacture. One typical circumstance of this character arises during the purification and recovery of benzene hexachloride from the reaction mixture provided by adding chlorine to benzene and forming benzene hexachloride As a rule, a considerable excess of benzene is present .and
must be removed. This is frequently accomplished by vaporizing the benzene from the benzene hexachloride. Temperatures for such vaporization are such that the benzene hexachloride is molten.
As already outlined, benzene hexachloride is con veniently offered for sale as a finely dividedsolid composition, usually asflaked benzene hexachloride. Flaking results, for example, from solidifying molten benzene hexachloride as a thin layer on the periphery of a rotating, cooled drum, andthereafter scraping the solidified benzene hexachloride on the drums periphery. The de- The inorganic alkaline solid may be added to the molten benzene hexachloride prior to distribution on the drums periphery. Molten benzene hexachloride formed during benzene removal may be directly fed to the flaking operation in which case the inorganic alkaline solid is incorporated in the benzene hexachloride after it is melted and before it is flaked.
Improved bag life is also realized by adding the inorganic alkaline solid to benzene hexachloride after it has been solidified as, for example, by dusting flaked recommended, e. g. solids of particle sizes up to 3 microns.
Subsequent to the incorporation of the minor concentration of inorganic alkaline solid in the benzene hexachloride ,with the consequent formation of a solid, particulate benzene hexachloride composition, the composition is packaged in paper bags (bags primarily ofcellulosic. materials) for storage, shipment and other con- .veniences. In many instances, the paper bags are large enough to contain from 50 to pounds of -benz ene hexachloride. In such sizes, .the packaged benzenehexachloride. can be shipped, stored and Totherwise handled with facility.
The following example demonstrates the manner in which the present invention may be practiced and the beneficial results stemming therefrom:
3 EXAMPLE In these tests flaked benzene hexachloride compositions comprising a normal chlorination isomeric mixture containing the specified concentration of inorganic alkaline solids were packaged in sealed paper bags and stored un- Table Description of Bagged Composition Test Comments Concen- Alkaline Solid tration, Weight Percent A {None Control Bag failure in 63 days.

The calcium carbonate employed in the above tests was finely divided product sold under the trade name Calcene; the calcium silicate was a finely divided product sold under the trade name Silene; the magnesium silicate used was that sold under the trade name Magnesol.
In tests A, B, C, D and E, the respective alkaline solids were added to molten benzene hexachloride prior to flaking. In test P, the alkaline solids were mixed with already flaked benzene hexachloride.
The foregoing data demonstrate the improvement in bag'life realized by incorporation of a minor quantity of inorganic alkaline solid in the benzene hexachloride packaged in paper bags. Thus, without inorganic alkaline solid present, bag failures occurred and almost always by the end of two months. In comparison, benzene hexachloride packaged in paper bags as herein specified did not encounter bag failure even after nine months.
The present invention is applicable to the packaging in paper bags of benzene hexachloride including the individual isomers as well as various isomeric mixtures. Of course, its use is usually in conjunction with isomeric mixtures of benzene hexachloride encountered in the addition chlorination of benzene. Thus, isomeric mixtures provided by the additive chlorination of benzene at temperatures from minus 80 C. to 70 C. are most frequently packaged. The isomeric mixture realized by additive chlorination of liquid benzene from which has been separated the solid benzene hexachloride that precipitates after substantial benzene conversion may also be packaged in this process. Removed isomers are mainly the alpha and beta isomers under such circumstances. Such benzene hexachloride compositions are comprised substantially of isomers of benzene hexachloride except for impurities present as an incident to their manufacture.
Inadequate paper bag life is most pronounced when benzene hexachloride containing from about to 200 parts per million by weight of hydrogen chloride is packaged. This minor quantity of hydrogen chloride is present in many benzene hexachloride compositions and can not easily be altogether removed. Thus, the present invention has particular relevance to packaging of particulate benzene hexachloride containing hydrogen chloride in the enumerated concentrations.
Quite a number of inorganic alkaline solids are useful for the purpose of extending bag life. Most useful have been the alkaline earth metal salts such as calcium salts, and more particularly the alkaline earth metal salts of Weak inorganic acids such as carbonic acid, silicic acid, etc. Most notable alkaline earth metal salts are calcium carbonate and calcium silicate. Other useful inorganic alkaline solids include magnesium salts such as magnesium silicate, calcium oxide, calcium bicarbonate, sodium phosphate, and the like. When the inorganic alkaline solids are finely divided, they function with high efliciency. Inorganic alkaline solids having particle sizes in the range of from 0.3 to 3 microns are of suitable subdivision in this regard.
Although the present invention has been described with reference to specific details of certain embodiments, it is not intended that it be construed as limited thereto except insofar as such limitations appear in the appended claims.
