Abstract: The invention relates to a process and a separation system for removing particles, in particular soot particles, from particle-containing process gas streams occurring in chemical or petrochemical plants. According to the invention, the particle removal is carried out in a partly thermally regenerable separation system. The particles are advantageously removed from the gas stream in a two-stage separation system, the first stage being composed of centrifugal separators, preferably multicyclones, and the second stage being composed of fine filters made of sintered metals, preferably of ferritic sintered metals. For the regeneration, the temperature is increased to a value above the ignition temperature of soot and, if required, an oxygen-containing auxiliary gas is added. The regeneration is preferably carried out periodically.

Abstract: The finishing agent contains a phosphazene of formula (I): (where R1 is a 1-10C (un)satd., branched/straight chain (cyclo)aliphatic, (opt. nitrated) aromatic, alkylaromatic or arylaliphatic gp., L is F, Cl or Br, -NR2R3, OH or -OR2 in which R2 and R3 may be H or a 1-18C (un)satd., straight chain/branched (cyclo)alkyl gp. and in which R3 may also be phenyl, or in which R2 and R3 can form a heterocycle with the N atom and Z is L or -N=PR3'). (I) are esp. used for heavy cotton fabrics (over 200g/m2). (2) are odourless and water -resistant.

Abstract: The invention relates to a method of recording magnetic signals on magnetic recording media containing an exchange-anisoptropic material at a temperature lower than, equal to or higher than the Neel temperature of this magnetic material. After the recording has been made, the magnetic recording medium is heated to a temperature equal to, or higher than, the Neel temperature, then cooled down to a temperature below the Neel temperature and the recording temperature, following which it is provided with an indicator which betrays re-heating.

Abstract: Title cpds. of formula (I): (where n is 0 or 1), starting materials for plant-protection agents, flameproofing agents, and adjuvants in the textiles and plastics sectors, are produced by reacting PCl3 with Cl2, NH3 and sulphur at not 40 degrees C. The process is simpler, safer in operation, and more economical than known processes, and gives (I) in better yields and purity.

Abstract: Method for purifying lactams by passing their vapours at temps. higher than their condensation point over or through activated carbon. Residence time is pref. 1-5 (esp. 2-3) sec. For epsilon-caprolactam, temp. used is 180-300 degrees C. Inert gas is opt. present. The carbon can be regenerated by solvent-extraction or superheated steam.
