Abstract: 1-Amino-2-(4-nitro- or amino-phenyl)-propane of formula (I) (where R is nitro or amino) are new cpds. which are prepd. by reacting 1-amino-2-phenylpropane (II) with HNO3 and opt. reacting the resulting (I; R = NO2) with a reducing agent. (I) are intermediates for dyes, pesticides, raw materials for paints, and pharmaceuticals; thus, reaction with phosgene at 150 degrees C gives corresponding mono- and diisocyanates which are useful as raw materials for paints (I; R = NO2) is useful as a solvent for nitrated aromatic hydrocarbons, while (I; R = NH2) is a specific solvent for aromatic amines.

Abstract: 2,4,6-Triaminotoluene is obtained by hydrogenation of trinitrotoluene in the presence of Raney nickel and dioxane as a solvent, the reaction temperature and pressure being chosen to be so high that the reaction proceeds at the rate of the addition of solution.

Abstract: Process for the manufacture of alpha -naphthol by hydrolyzing alpha -naphthyl esters of aliphatic carboxylic acids in a distillation column by means of steam in counter-current at a particular temperature, and in a certain ratio, in the presence of organic sulfonic acids. The alpha -naphthol obtainable by the process of the invention is a valuable starting material for the manufacture of dyes, drugs and insecticides, e.g. alpha -naphthyl N-methylcarbamate.

Abstract: Synthesis gas is prepd. by gasifying still moist clarifying sludge, (A), with additional fuel (B), e.g. C dust, heavy heating oil and combustible waste. The generated gas can be used as heating- or synthesis gas. All substances in (A) are oxidised odourlessly. (B) quantity should be sufficient to use the water in (A) to gasify the organic components of (A) and (B). The 2nd gasifying agent is O2, e.g. as air or O2-enriched air. A self-feeding combustion process is advantageous, e.g. at 900-1000 degrees C. Standard reactors can be used, esp. turbulent layer- or rotary furnaces, but not countercurrent generators.

Abstract: Citric acid is prepd. by (a) treating 3-methylene-pentanediol-1.5 (I), with a soln. of 0.5-1 mol. N2O3 in 10-20 mol. 50-70wt. % HNO3, both mol. quantities referring to 1 mol. (I) at -10 to +10 degrees C, for a short time; then (b) heating the mixt. to 35-60 degrees C, until oxidn. to citric acid is completed and recovering the citric acid after HNO3 sepn. Citric aicd yield and purity are increased. Quantity of waste gas, consisting mainly of N2, is reduced.
