Abstract: The present invention relates to a process for the preparation of 1-[4-nitro-2-(trifluoromethyl)-phenyl]-alkanones and substituted phenoxyphenyl ketones.

Abstract: The present invention relates to a process for the preparation of ?-methyl-[4-(nitro)-2-(trifluoromethyl)]-benzyl nitrate and to the ?-methyl-[4-(nitro)-2-(trifluoromethyl)]-benzyl nitrate.

Abstract: A container having integrated liquid product dispensers for enabling transport of a plurality of liquid product dispensing receptacles defines a base pouch defining a five solid sided pouch housing with an open top, a fastenable flap attached to the base pouch, and a receptacle fastening system enabled from the interior of the base pouch. The fastenable flap includes an elastic section that extends from the base pouch and which stretches over the open top of the base pouch when the flap is closed and a non-elastic section attachable to front side of the base pouch. A suitable liquid product dispensing receptacle includes a receptacle fastening surface near the bottom of its exterior surface. The receptacle fastening surface and an interior fastening strip inside the base pouch form the receptacle fastening system and enable such a receptacle to be fixed in place in the base pouch in an upright position.

Abstract: A process for removing carbon dioxide (CO2) by means of an absorption medium from a cycle gas system, wherein the CO2 occurs within a process in which, in the gas phase, ethylene is oxidized by oxygen (O2) to ethylene oxide (EO) in the presence of a catalyst, in which, as by product, CO2 is generated, by using as absorption medium an aqueous solution of one or more amines, wherein, for further purification of the cycle gas stream obtained downstream of the CO2 absorption step, this cycle gas stream is brought into intimate contact with water to which no mineral acid and no higher glycol was added.

Abstract: Absorption medium for acid gases comprising an oligoamine (A) of the general formula (I) and a piperazine derivative (B) of the general formula (II) in which the weight ratio of oligoamine (A) to the piperazine derivative (B) is 0.2 to 25, and also process for removing acid gases from a gas stream by contacting the gas stream at a pressure of 0.05 to 10 MPa abs with an aqueous solution of said absorption medium which is brought to and maintained at a temperature of 20 to 80° C.

Abstract: Absorption medium for acid gases comprising an oligoamine (A) of the general formula (I) and a primary or secondary alkanolamine (B) of the general formula (II) in which the weight ratio of oligoamine (A) to the primary or secondary alkanolamine (B) is 0.2 to 4, and also the process for removing acid gases from a gas stream by contacting the gas stream at a pressure of 0.05 to 10 MPa abs with an aqueous solution brought to and maintained at a temperature of 20 to 80° C. of said absorption medium.
