Chemical Impregnating Company

Porter did not mention in his letter to Director Hobby was the employment of Waacs in chemical impregnating companies in the zone of the interior. As mentioned above, this possibility had been considered in the fall of 1942. In April 1943 the CWS conducted an experiment with sixty Waacs at Edgewood Arsenal to determine whether they could be used on the work of impregnating protective clothes with chemicals. The experiment proved successful beyond all expectations, and henceforth Waacs were assigned to those units, which for semantic reasons were redesignated "processing companies. ... 

By the end of 1943, ten more chemical processing companies had arrived in the United Kingdom, had been equipped with two theater of operations impregnating plants each, and had been installed, usually within or adjacent to quartermaster clothing depots. A number of... 

The needs of gas warfare readiness, therefore, set the pattern for prewar CWS planning for service units. The prescribed standard for a wartime situation, in which the existence or at least the imminence of gas warfare was taken for granted, called for the assignment of a chemical depot company, decontamination company, laboratory company, impregnating company (as the processing company was then called), and maintenance company to each field army, with additional... 

An impregnating company was not provided at this time because mobile impregnating apparatus was not yet standardized. With this exception, the 1940 activations provided opportunities to test out the organizational and training requirements of the several types of chemical service units, inasmuch as one depot company had previously been activated.

Catalysts A, prepared from aluminum isopropoxide and calcined at 700° for 4 hours A—Na, contained 1 % by weight of sodium by impregnation with sodium carbonate A—H, purchased from Harshaw Chemical Company it contained 0.35% of sodium. HLSV = hourly liquid space velocity, grams of alcohol per gram of catalyst per hour. 

Packed columns contain an inert and stable porous support on which the stationary phase can be impregnated or bound (varying between 3 to 25%). The solid support is made of spheres of approximately 0.2 mm in diameter, obtained from diatomites, silicate fossils (such as kieselguhr, tripoli) whose skeleton is chemically comparable to amorphous silica. These materials, which have a specific surface area ranging from 2 to 8 m2/g, have been commercialised by several companies such as Johns Manville, under the name of Chromosorb , and are used universally. Other synthetic materials have been developed such as Spherosil , made of small silica beads. All of these supports have a chemical reactivity comparable to silica gel because of the presence of silanol groups. 

Already in 1943 Imperial Chemical Industries (26) applied for a patent on treatments of paper and textile fabrics with vapor of monomeric, readily polymerizable compounds after impregnation with a mixture of persulphuric acid or water-soluble persulphate and of water-soluble oxyacids of sulphur or their salts with reducing properties. In 1951 and in 1952 the same company (27) filed applications on the syn-... 

Catalysts. The properties of the two catalysts used in this study are given in Table II. The Monolith catalyst was prepared in the laboratory at OSU by impregnating Co and Mo on the Monolith alumina support received from the Coming Glass Company. The Nalcomo 474 catalyst was received from the Nalco Chemical Company and is a commercial preparation used as a reference catalyst in this study.
