    Abstract: The present invention relates to a method for producing mineral oil from underground mineral oil deposits, in which an aqueous formulation comprising at least a mixture of alkyl ether carboxylate and corresponding alkyl ether alcohol, where the alkyl ether carboxylate has been prepared from the alkyl ether alcohol and the molar ratio in the mixture of alkyl ether carboxylate:alkyl ether alcohol is from 51:49 to 92:8, is injected through at least one injection well into a mineral oil deposit, where the deposit has a deposit temperature of 55° C. to 150° C., a crude oil having more than 20° API and a deposit water having more than 100 ppm of divalent cations, and crude oil is withdrawn through at least one production well from the deposit. The invention further relates to the preparation of the mixture and to a concentrate comprising the mixture.

    IPC: C07F9/22

    Abstract: Provided herein is a process for isolating at least one (thio)phosphoric acid derivative, which has a boiling point of at least 70° C., from a product mixture including the at least one (thio)phosphoric acid derivative, at least one salt selected from ammonium salts and alkali metal chlorides, at least one polar solvent selected from the group consisting of ester solvents and ether solvents, and optionally at least one HCl scavenger; wherein the process is based on first dissolving the (thio)phosphoric acid derivative to be able to remove the at least one salt, and then causing solids formation of the (thio)phosphoric acid derivative.

    IPC: C07D307/79

    Abstract: The present invention relates to a process for preparing benzylic amides of formula I wherein the variables have the meaning as defined in the description, by reductive amidation of a nitrile of formula II wherein the variables have the meanings given for formula I, with an activated carbonyl compound of formula III, and which nitrile is obtained by reaction of a compound of formula IV with a halogen compound of formula V, wherein X is a halogen atom, preferably bromo, which halogen compound V in turn is obtained by Sandmeyer reaction of an aniline derivative of formula VI novel compounds of formula I, and processes for preparing compounds of formula XII wherein the variables have the meaning as defined in the description by condensing compounds of formula I with compounds of formula X and subjecting the resulting α,β-unsaturated ketone of formula XI to a reaction with hydroxylamine to yield compounds of formula XII.

    IPC: C07C51/235 ,  C09K5/20 ,  C23F11/12

    Abstract: A process for preparing an anticorrosion component for an antifreeze by oxidizing an oxydiol of the formula (I) with molecular oxygen at a temperature of 20 to 100° C. and a partial oxygen pressure of 0.01 to 2 MPa in the presence of water and of a heterogeneous catalyst. The catalyst contains platinum to form an oxydicarboxylic acid of the formula (II) The process has the steps of conducting the oxidation (a) at a molar ratio of 0.002≤n(Pt)/[n(oxydiol (I))+n(oxydicarboxylic acid (II))]≤0.019; (b) at a concentration of water of 50% to 95% by weight in the liquid phase; and (c) at a pH of 1 to 7.
