Abstract: Diisocyanates production includes supplying gas flow containing diamine and phosgene to reaction zone, separating surplus phosgene and hydrogen chloride gas from gaseous reaction mixture, feeding back the separated phosgene into the reaction, and separating hydrogen chloride (15 wt.%) from the feedback phosgene stream. The mass fraction of hydrogen chloride in the phosgene-containing stream before mixing with the amine-containing stream is less than 15 wt.%. A chlorobenzene inert medium with gas volume of more than 0.0001-30 is added to the diamine- and/or phosgene-containing gas stream. Diisocyanates production includes supplying gas flow containing diamine and phosgene to reaction zone, separating surplus phosgene and hydrogen chloride gas from gaseous reaction mixture, feeding back the separated phosgene into the reaction, and separating hydrogen chloride (15 wt.%) from the feedback phosgene stream. The mass fraction of hydrogen chloride in the phosgene-containing stream before mixing with the amine-containing stream is less than 15 wt.%. A chlorobenzene inert medium with gas volume of more than 0.0001-30 is added to the diamine- and/or phosgene-containing gas stream. The reaction of the diamine with phosgene takes place in a reaction chamber (IV) at 0.1-20 bar and at 200-600[deg]C. The flow in the reaction chamber exhibits Bodenstein number of more than 10. The average contact time of the reaction mixture is 0.001-5 seconds, and the molecular ratio of phosgene to amino groups is 1.1: 1-20: 1. The isocyanate is 1,6-diisocyanatohexane, 1-isocyanato-3,3,5 tri methyl-5-(isocyanatomethyl) cyclohexane, 4,4 '-di(isocyanatocyclohexyl)methane and toluylene diisocyanate isomeric mixtures.

Abstract: A method is provided for the intrinsically safe handling of 3-chloropropyne in the presence of a diluent with a boiling point ranging from -50° C. (223 K) to 200° C. (473 K) under atmospheric pressure, wherein the concentration of 3-chloropropyne in the liquid phase and in the gas phase is kept below the concentrations capable of deflagration by means of the type and amount of the diluent, the temperature and the total system pressure, together with the use of a 3-chloropropyne prepared, stored or transported in this way in the synthesis of dyestuffs, pharmaceutical and agricultural active ingredients, electroplating auxiliaries, disinfectants, steroids and growth hormones.
