    Abstract: A process for the production of solid or paste-form products by fast reactions is carried out stoichiometrically wherein a gaseous medium is introduced into each of the reactants to be reacted with one another, the reactant streams formed are combined and are subsequently forced through a spray unit in a weight ratio of gaseous medium to product stream of from 0.04 to 0.3 (kg/kg) and at a rate of 0.1 to 15 m/second, as calculated from the gas-free reactant streams and based on the free cross-section of the spray unit. The products obtained are free from readily volatile constituents.

  • Patent number: 5132432
    Abstract: The invention relates to novel fluorescent dyes based on the following pyrenyloxy sulfonic acid structure: ##STR1## wherein at least one of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 is --OCH.sub.2 C(O)OCH.sub.3, --OCH.sub.2 CON(O)H, --OCH.sub.2 CON.sub.3, --OCH.sub.2 CONHNH.sub.2, ##STR2## or --CH.sub.2 CONH(CH.sub.2).sub.n NH.sub.2 where n is an integer from 1 to 10; at least one of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 is sulfonic acid or alkali salts of sulfonic acid; and all other of R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are hydrogen or a hydroxyl group. The new reagents contain functional groups typically found in biomolecules or polymers. The spectral properties of the fluorescent dyes are sufficiently different in wavelengths and intensity from fluorescein as to permit simultaneous use of both dyes with minimum interference.
