Definitions
- the method should have a process sequence that is as easy to handle as possible and should work relatively quickly.
- the method comprises grinding the reactants while entering a more or less large amount of mechanical energy.
- a fine distribution into very small particles and thereby an intensive mixing of all components of the mixture is brought about, so that intensive contact is established on average over time with the reagents used and these are brought to the desired reaction.
- the reactivity of the solid components is increased by the fine distribution due to surface-physical effects.
- the process basically works at low temperatures, preferably at room temperature under normal pressure. However, it is possible that the intensive introduction of mechanical energy and / or the heat of reaction liberated during dehalogenation causes heating in the course of the process.
- the metallic reducing agent is advantageously used at least in a slight excess.
- the required amount of reducing agent can be determined in preliminary tests on samples of the specific decontamination object.
- aliphatic amines and lower primary or secondary aliphatic amines are preferred.
- suitable amines are: primary, secondary or tertiary aliphatic and alicyclic mono- or polyamines,
- certain amides can also be considered.
- 1,3-dimethyl-3,4,5,6-tetrahydro-2 (1H) -pyrimidone (diethyl propylene urea, DMPU), 1,3-dimethyl-2-imidazolidinone (N, N-dimethylethylene urea) can be used , DMEU), l-methyl-2-pyrrolidone (NMP), l-ethyl-2-pyrrolidone, N, N-diethylacetamide, N, N-diethylpropionamide, N, N-diethylisobutyramide.
- a separate addition of a hydrogen source can be dispensed with if it is known that a substance suitable as a hydrogen source is already present in sufficient quantity in the mixture to be treated.
- the grinding aid (s) and / or reaction accelerator can be added to the substance or mixture of substances in a subsequent step, i.e. separately after the addition of the reactants, and mechanically incorporated.
- the metallic reducing agent can be added directly to the batch in pure form. This is particularly useful for alkaline earth metals, which are less reactive in air than the alkali metals, e.g. with magnesium chips.
- the method can also be used to complement other methods, e.g. of washing processes, can be used or combined with these.
- a previous treatment of contaminated soils with calcium oxide (quicklime or quicklime), which is also known in other treatment processes and among other things. used to dry the mixture may be useful in some cases.
- Chlophene-contaminated sea sand (model) / Mg / n-propylamine In a centrifugal ball mill S 1 (see, example 5), 15 g of sea sand (pA), 1 g of calcium oxide-calcium hydroxide mixture, 0.25 ml of n-propylamine, 0 , 1 g of Chlophen A30, and 0.76 g of magnesium shavings for 1 hour at high speed.
- Detoxified materials such as Building materials or waste oils can be sent to useful recycling measures or recycled.
- PCB-contaminated building materials and building equipment (wall coatings, fine plaster, elastic expansion and window joint compounds in buildings of different types);
