Definitions

  • the invention relates to a deodorizing formulation, in particular for a mixture of bitumen and sulfur, which contains active, odor-reducing agents and a diluent, and to processes for the preparation of a composition based on sulfur, which can be used for odor reduction.
  • bitumen processing can be carried out at lower temperatures in the range of 130 to 150 ° C.
  • US-A-3,960,585 and WO 2005/059016 disclose that the formation of hydrogen sulfide upon heating a mixture of asphalt and sulfur can be suppressed by the addition of free radical-forming inhibitors and / or redox catalysts. However, these additives are not sufficiently effective.
  • the invention therefore an object of the invention to suppress or at least reduce this odor nuisance in mixtures of bitumen and sulfur.
  • a deodorizing formulation according to claim 1 comprising active agents and at least one diluent, the active agents comprising the following components:
  • the active agents consist of the following components:
  • EP-A 1 235 768 and WO 2009/019 041 describe processes for reducing the odor of bitumen in which odor-reducing formulations are mixed into liquid bitumen, which in particular contain certain carboxylic acid esters or certain aldehydes.
  • the foul-smelling volatiles of bitumen consist essentially of organic sulfur and nitrogen compounds, while in the present case especially hydrogen sulphide and sulfur dioxide must be eliminated.
  • the bitumen / sulfur mixture preferably contains minor amounts of sulfur, in particular 20 to 40 wt.%.
  • the deodorizing formulation of active agents and diluents is preferably incorporated into the bitumen / sulfur mixture in amounts of from 50 to 1000 ppm, in particular from 100 to 500 ppm, the formulation preferably being from 5 to 50% by weight and in particular from 10 to 40% by weight of active agents and from 95 to 50% by weight, in particular from 90 to 60% by weight, of diluent.
  • Component A is preferably benzyl salicylate, but other alkyl salicylates having 1 to 8 carbon atoms in the alkyl radical are also suitable, for example methyl salicylate.
  • Benzylsalicylate has the great advantage that it is extremely high due to its very high boiling point low vapor pressure, so that the deodorizing formulation remains effective in the mixture of bitumen and sulfur for a long time, eg several months.
  • Component B is preferably heptanal or dodecanal.
  • the further aldehydes of component C are preferably selected from:
  • the alcohols of component D are preferably naturally occurring alcohols selected from:
  • Limonene (1-methyl-4-prop-1-en-2-ylcyclohexene C] 0 Hi 6 ).
  • the optional ketones of component F are preferably selected from:
  • Benzophenone butyl methyl ketone and 1,8-cineole.
  • the active agents are used together with a diluent.
  • the deodorizing formulation causes the deodorizing formulation to be in liquid form. At the same time it acts as a mixing agent when mixing the individual components. In addition, it prevents that evaporate at relatively high temperature individual relatively low-boiling components of the active agents.
  • Preferred diluents are mineral oils, ie hydrocarbon middle distillates, such as CATENEX from SHELL, and vegetable oils, such as sunflower oil or mixtures thereof.
  • the present invention further relates to a method according to
  • a deodorant composition based on sulfur and 0.02 to 0.3% by weight of the deodorizing formulation, if appropriate together with 0 to 8% by weight of other additives, is initially used , each based on sulfur produced.
  • Suitable additives are processing aids, for example ethylenebisstearylamide or amyl acetate, and colorants, for example carbon powders. This mixture can then be incorporated at 140 to 170 ° C in liquid bitumen.
  • sulfur based means that sulfur is the essential ingredient of the composition.
  • the first deodorizing agent Preferably, the first deodorizing agent
  • Mixture of sulfur and optionally the processing aid and the colorant to produce and apply the deodorizing formulation on the particles on the surface for example, according to customary in plastics technology by spraying, by tumbling or by compounding.
  • a mixture of active agents was prepared from:
  • a mixture of active agents was prepared from:

Abstract

L'invention concerne une formule désodorisante, notamment pour un mélange de bitume et de soufre, laquelle formule contient des agents actifs atténuant les odeurs, à base d'esters d'acide salicylique, d'aldéhydes et éventuellement d'alcools, ainsi qu'un diluant. L'invention concerne en outre des procédés de préparation d'une composition désodorisante à base de soufre, laquelle peut être incorporée au bitume en vue d'atténuer les odeurs.
