Most of these communications concerned the problems experienced by Poelitz when its regular supplier of Sulfigran (sodium sulfide), the I.G. Farbenindustrie plant at Luverkusen, had to shut down for repairs and Poelitz had to get an impure form of Sulfigran mixture (a crude melt of ore) from other suppliers, including the I.G. Farbenindustrie plant at Wolfen (Bitterfeld). Various problems arose in the transition, including the fact that the mixture supplied was not ground finely enough for the coal-paste-preparing machinery at Poelitz to handle without damage. An analysis of one sample of the raw melt mixture gave 68.8% sodium sulfide, 12.0% carbon, 1.5% hydrogen, 1.6% silicon dioxide, 1.8% iron, 1.0% aluminum, 0.6% calcium, traces of magnesium and sulfate, and 15.4% water-insoluble. An analysis for another sample showed about 1.8% less sodium sulfide, 1.5% more silicon dioxide, 0.7% less iron, 0.5% less aluminum, 0.6% more calcium, etc., than the previous analysis. Finally one of the communications was a letter in which Ludwigshafen responded favorably to Poelitz's question about whether it would be advantageous to add Sulfigran directly to the first oven of a hydrogenation chamber instead of grinding it with the coal paste. Ludwigshafen said that in some experiments it had observed deposits at places where Sulfigran and coal paste encountered each other in preheater tubes. The deposits consisted of sodium sulfide and iron compounds. 3 tables.
