Abstract: A process for removing capsule oils from carbonless copy paper involving: (a) providing carbonless copy paper containing capsule oils; and (b) disintegrating the carbonless copy paper in the presence of an alkoxylated C12-14 alcohol to form a stock suspension.

Abstract: A method of controlling or preventing foam in an aqueous system is provided, wherein an effective amount of an alkoxylated, epoxidized fatty compound that has been ring-opened with a nucleophile is determined and added to the system. After ring opening with the nucleophile, the epoxidized fatty compound is alkoxylated with an alkylene oxide selected from the group consisting of ethylene oxide, propylene oxide, and butylene oxide.

Abstract: A process for controlling the deposition of stickies from paper stock suspensions during papermaking by adding to the paper stock suspensions from 0.001% to 5.0% by weight based on the weight of fibrous paper stock, of alkoxylation products obtained by reaction of alkylene oxides with C.sub.10-22 carboxylic acid derivatives or C.sub.10-22 carboxylic acids containing functional groups with at least one OH group in the 9, 10, 13 or 14 position.

Abstract: The invention relates to aqueous dispersions containing A. C.sub.6-22 carboxylic acids and/or resinic acids and B. C.sub.6-22 oxoalcohols alkoxylated with 2 to less than 6 mol C.sub.2-4 alkylene oxides for deinking printed wastepaper.

Abstract: A process for controlling the deposition of stickies from paper stock suspensions in papermaking involving the steps of: (a) providing a paper stock suspension containing stickies; and (b) contacting the stickies in the paper stock suspension with a native starch.

Abstract: A process for removing printing inks from printed wastepaper in the presence of a deinking chemical is provided. In this process printed wastepaper is disintegrated to form a paper stock suspension and the detached printing ink particles are removed in known manner by flotation or washing in another stage. In this process, alkoxylates of blown oils are used as the deinking chemical. The deinking chemical is added during disintegration and/or before the flotation or washing step. Preferably, the printed wastepaper is disintegrated in the presence of 0.02 to 2% by weight and preferably 0.1 to 0.8% by weight, based on air-dry paper stock, of alkoxylates of blown oils. This deinking chemical also removed printing inks from paper circuit waters.

Abstract: The invention relates to a process for controlling the deposition of stickies from paper stock suspensions in papermaking. According to the invention, the deposition of stickies is controlled by addition of an effective quantity of a degradation product of native starch to the paper stock suspension.

Abstract: The invention relates to the use of compounds containing polyether chains prepared by reaction of epoxidized C.sub.10-22 carboxylic acid derivatives with polyalkylene glycols having average molecular weights of 100 to 2,000 and/or certain alkoxylated aliphatic compounds for the removal of printing inks from printed wastepaper and/or paper circuit waters.

Abstract: The invention relates to aqueous dispersions of alkaline earth metal soaps and/or alkaline earth metal resin soaps for deinking printed wastepaper in which the dispersions containA. alkaline earth metal salts of C.sub.6-22 carboxylic acids and/or resinic acids andB. C.sub.6.22 oxoalcohols alkoxylated with 2 to less than 6 mol C.sub.2-4 alkylene oxides and alkali metal and/or alkaline earth metal alumimo silicates corresponding to general formula I0.7-1.5 cat.sub.2/n O.Al.sub.2 O.sub.3.0.8-6 SiO.sub.2in which cat represents alkali metal and/or alkaline earth metal cations and n is the valency of the alkali metal and/or alkaline earth metal cations.

Abstract: The invention relates to a process for the flotation of fillers from deinked waste paper in the presence of surfactants containing sulfonate groups.

Abstract: The invention relates to a process for deinking wastepaper in the presence of at least partly water-soluble polymers and/or copolymers containing amino and/or ammonium groups. Two examples of appropriate polymers/copolymers are neutralized polyethyleneimine and quaternized hydroxyethyl cellulose.

Abstract: The invention relates to a process for the removal of fillers from waste paper, after floatation of the printing ink, in the presence of at least partly water-soluble polymers and/or copolymers having number average molecular weights of 1,000 to 500,000 by flotation.

Abstract: The invention relates to a process for the flotation of fillers from deinked wastepaper in the presence of organic phosphoric acid esters. The flotation of the fillers occurs after deinking the wastepaper by flotation.

Abstract: In a process for processing waste paper, aqueous suspensions of pulp are treated with cationic layer compounds precipitated in situ. The separated printing inks, fillers and/or unwanted substances are then removed from the fibrous suspensions in a known manner by flotation or washing out.

Abstract: According to the invention, wastepaper is refined in the presence of alkoxylation products obtainable by reaction of alkylene oxides with C.sub.10-22 carboxylic acid derivatives and/or C.sub.10-22 carboxylic acids containing carboxylic acid residues with at least one OH group in the 9, 10, 13 and/or 14 position and the detached printing ink particles are subsequently removed from the paper stock suspensions by flotation or washing.
