  • Patent number: 11390794
    Abstract: The invention relates to a process for mineral oil production, in which an aqueous saline surfactant formulation comprising a surfactant mixture of at least one anionic surfactant of the general formula R1—O—(CH2C(CH3)HO)x—(CH2CH2O)y—SO3M and at least one anionic surfactant of the general formula R2—O—(CH2CH2O)z—SO3M and a base is injected through injection boreholes into a mineral oil deposit, and crude oil is withdrawn from the deposit through production boreholes. The invention further relates to the surfactant mixture, a concentrate comprising the surfactant mixture and a manufacturing process as well as the use of the surfactant mixture and the con- centrate in the production of mineral oil from underground mineral oil deposits.
    Type: Grant

  • Patent number: 9109200
    Abstract: The invention relates to the use of an enzyme preparation which catalyzes the degradation of formaldehyde for reducing the formaldehyde content in a formaldehyde-containing formulation. In a preferred embodiment, the enzyme preparation contains a formaldehyde dismutase from a Pseudomonas putida strain. Further, the invention refers to a process for reducing the formaldehyde content in cross-linking agents for textile finishing or in polymer dispersions used, e.g. in construction chemistry. Further the invention relates to the use of an enzyme preparation which catalyzes the degradation of aldehydes for reducing the formaldehyde content in an aldehyde-containing formulation. Furthermore, the invention relates to a novel variant of the formaldehyde dismutase from Pseudomonas putida.

  • Patent number: 8187373
    Abstract: Printing inks for offset and/or letterpress printing which comprise NIR absorbers, and solubility of the NIR absorber in the printing ink is at least 0.1% by weight. NIR absorbers consisting of cyanine cation with an anion which has long-chain alkyl or aralkyl groups. Use of such printing inks for printing processes in which the curing of the printing ink is promoted by using IR lasers. NIR absorbers comprising a cyanine cation with an anion which has long-chain alkyl or aralkyl groups.
