Abstract: The use is described of a mixture containing A) at least two different acrylic acid C1-C6 alkyl esters; B) at least one compound from the group comprising C1-C8 mercaptans, C4-C12 thiophenes, C2-C8 sulfides or C2-C8 disulfides; C) at least one compound from the group comprising norbornenes, C1-C5 carboxylic acids, C1-C8 aldehydes, C6-C14 phenols, C7-C14 anisoles or C4-C14 pyrazines; D) optionally an antioxidant for the odorisation of fuel gas having a methane content of at least 60 wt. %. Corresponding fuel gases and processes for the odorisation of fuel gases are also described.

Abstract: The present invention describes a method for the determination of the concentration of acrylic acid C1-C8 esters in fuel gas, with the following step: bringing the fuel gas containing acrylic acid C1-C8 esters into contact with palladium molybdate, so that a change in colour takes place.

Abstract: A mixture of acrylic acid and nitrogen compounds is particularly adapted to achieve a sulfur-free odorization of a gas.

Abstract: The present invention relates to acrylic acid alkyl ester mixtures containing a low proportion of sulphurous compounds, the use of these to odorize liquid gas, a method for odorizing liquid gas and liquid gas containing these mixtures.

Abstract: Fatty acid lower alkyl esters can be used as effective constituents in compositions comprising fatty acid lower alkyl esters and perfume compositions, fragrances or perfume oils for setting the viscosity of the composition.

Abstract: The invention relates to a denaturant for ethanol, to ethanol comprising this denaturant and to cosmetic products comprising this denatured ethanol.

Abstract: Aliphatic dicarboxylic acid esters of the formula ##STR1## in which R denotes a methyl or isopropyl group andn represents the number 9 or 10,are used as scents. They can be employed as components in perfume compositions and perfumed products.
