Surfactants of the general formula (I) in which Ris a linear or branched akyl radical having 6 to 20, especially 10 to 16 C atoms, Rand Rindependently of one another are H or HCO, and M is hydrogen, an alkali metal or a moiety NRRR, in which R, Rand Rindependently of one another are hydrogen, an alkyl group having 1 to 6 C atoms or a hydroxyalkyl group having 2 to 6 C atoms, are readily incorporated into laundry detergents or cleaning products, possess outstanding performance qualities and can be prepared on the basis of renewable raw materials. 

Anionic surfactants and detergents comprising them

Surfactants of general formula (I), in which Rdenotes a linear or branched alkyl residue having 6 to 20, and in particular 8 to 14 carbon atoms, Rdenotes H or CH, and M denotes hydrogen, an alkali metal or an NRRRgrouping, in which R, Rand R, independently of one another, denote hydrogen, an alkyl group having 1 to 6 carbon atoms or a hydroxyalkyl group having 2 to 6 carbon atom, can be easily incorporated into washing or cleaning agents, have outstanding application-related properties, and can be produced based on renewable resources.

The present invention discloses a process for the conversion of phenolics into aromatic hydrocarbons. In more detail, the present invention refers to a process for the selective hydrodeoxygenation of phenolic feeds into aromatic hydrocarbons, such as benzene, toluene, alkylbenzenes and others. The selective catalytic hydrodeoxygenation is performed in absence of external supply of molecular hydrogen.

The present invention relates to a method for obtaining a high yield of sugar alcohols containing five to six carbon atoms from cellulose-containing materials. In a first step the starting materials (for example microcrystalline cellulose, alpha-cellulose, wood and cellulose-containing residues, such as sugar cane bagasse or wood shavings) and an acid are brought into close contact with the substrates by a impregnation carried out in the liquid or gaseous phase. In addition, in a second step the starting materials impregnated with acid and preferably dried are brought into contact by the action of mechanical energy, such that the cellulose-containing materials are degraded into water-soluble products. Subsequently, in a third step, sugar alcohols having five to six carbon atoms are obtained in a high yield and in high selectivity from the water-soluble products in aqueous solution by hydrolytic hydrogenation by means of a metal-containing catalyst under hydrogen pressure.
