The present invention relates to aroma chemical compositions containing 3,5-diethyl-2-propyl-tetrahydropyran, a 3,5-diethyl-2-propyl-dihydropyran or a 3,5-diethyl-2-propyl-pyran, a mixture of such compounds, a stereoisomer of one of these compounds, or a mixture of stereoisomers of one or more of these compounds. The invention further relates to a method for preparing such compounds, stereoisomers or mixtures thereof, to the composition obtainable by this method, to the use of such compounds as an aroma chemical or for modifying the scent character of a fragranced composition; and to a method for preparing a fragranced composition or for modifying the scent character of a fragranced composition using said compounds. Moreover, the invention relates to 3,5-diethyl-2-propyl-tetrahydropyran, to its stereoisomers and to mixtures of these stereoisomers.

Additive formulation suitable for antistatic modification and improving the electrical conductivity of inanimate organic material

An additive formulation suitable for antistatic modification and improving the electrical conductivity of inanimate organic material, consisting essentially of (A) from 1 to 50% by weight of an olefin-sulfur dioxide copolymer, (B) from 1 to 50% by weight of a compound which comprises one or more basic nitrogen atoms and has at least one relatively long-chain linear or branched hydrocarbon radical having at least four carbon atoms or an equivalent structural element which ensures the solubility of component (B) in the inanimate organic material,(C) from 0.1 to 30% by weight of an oil-soluble acid and(D) from 1 to 80% by weight of a high-boiling organic solvent which consists of one or more molecule types, where at least 80% by weight of these molecule types have a boiling point of more than 150&#xb0; C. at standard pressure,where the sum of all components adds up to 100% by weight.

The present invention relates to a process for preparing 2-alkylpolyisobutenylphenols and their Mannich adducts, to compositions obtainable by this process and to their use.
