The invention relates to a novel, highly efficient tobacco smoke filter provided with mechanically (fibrous) and/or adsorptively filtering materials as well as chemosorptively filtering components, which comprises a synergistic composition containing at least one of a compound having a high nucleophilic additivity, capable of chemically reacting and stable adduct forming with excited and ground-level aldehydes not filtered out by the mechanically and/or adsorptively filtering materials; and at least one of a compound containing ##STR1## enediol structural moieties, wherein the enediol type compound or its combination suitably amount to at least 50% by weight of the other chemosorptive components and 40 to 300% by weight of the adsorptively filtering materials.

Highly efficient tobacco smoke filter

A process for producing cigarette filters comprising a compound containing L-ascorbic acid and having the compound added to an adsorptional filter material in a quantity of 5-200% of the amount of said adsorptional filter.

The invention relates to a new method for increasing the biological value of manures, dung-waters, organic wastes and/or soils rich in lysine. According to the invention manure, dung-water, an organic waste and/or soil rich in lysine, either of natural composition or supplemented with lysine, a lysine source and/or one or more agricultural chemical(s), is treated with at least 0.01 mole of formaldehyde or an equivalent amount of a formaldehyde source, calculated for one mole of free or bound lysine present. The treatment according to the invention results in a significant increase of plant growth and crop yield.

Method for increasing the biological value of manures, dung-waters,

The invention relates to a process for nucleophilic substitution reactions. According to the invention the reaction is carried out in a hetergeneous system, consisting of a solid and a dissolved reactant, one or several organic solvents, one or several linear polyether derivatives, and/or amino compounds and water. The volume of the water is preferably at the most 100% of the volume of the organic solvent and more preferably 5%.

Process for heterogeneous nucleophilic substitution reactions

The invention relates to a process for nucleophilic substitution reactions. According to the invention the reaction is carried out in a heterogeneous system, consisting of a solid and a dissolved reactant, one or several organic solvents, one or several linear polyether derivatives, and/or amino compounds and water. The volume of the water is preferably at the most 100% of the volume of the organic solvent and more preferably 5%. According to the invention the anhydrous reaction medium which is difficult to ensure, is not necessary and the use of the expensive and in industrial scales unavailable crown ethers is eliminated.
