The first step, that of the manufacture of phenyl arsinic acid, was carried out at Ludwigshafen in one of the existing azo dye sheds without any alteration of plant, just as a new azo dye might have been produced in the same shed. It is believed that another dye factory also produced this substance. At Ludwigshafen the conversion to diphenyl arsinic acid occurred.
The attached table shows us how the production of any particular war chemical involved a number of stages, each of which occurred in a different factory. The directors of the I.G. simply chose a particular plant in a particular factory which was most suited for the operation concerned. They Phenyl Carbylamine 1. Aniline Condensation of aniline Kalle Chloride 2. Chlorine with carbon bisul 3.
But the technique of the German dye industry solved this as satisfactorily and as steadily as other chemical warfare problems, bringing its technical experience to bear on the different difficulties involved. Diphenychlorarsine. This was the earliest and main constituent of the familiar Blue Cross shell. It was prepared in four stages: The preparation of phenyl arsinic acid.
Then he partially awakens, and repeats the dream to himself, because he wants to tell it to me. He is distinctly afraid of the analysis of the dream. He is much excited during this semi-sleeping state, and repeats continually, "Phenyl, phenyl." II. He is in ... ing with his whole family; at half-past eleven.
The conversion of the above to phenyl arsenious oxide. The conversion of the latter into diphenyl arsinic acid. The conversion of the latter into diphenyl-chlor-arsine. This is another example of a highly complicated product which might have presented great difficulties of production, but the problem of whose manufacture was solved, almost automatically, by the German organisation.
