26 Jun 2006TL;DR: In this article, a phenol-formaldehyde-binder is applied onto the still hot fibers after the fiberization of a mineral wool, using a binder that comprises hydroxylamine or an amino alcohol with the following general formula (I) wherein R1 and R2 are the same or different from each other, and independently are hydrogen, a linear or branched, saturated or unsaturated aliphatic hydrocarbon with 1 -12 carbon atoms, a saturated or nonsaturated alicyclic or heterocyclic aromatic hydrocarcarbon with 5-8
Abstract: The present invention relates to a binder for the production of bonded mineral wool, wherein a phenol-formaldehyde-binder is applied onto the still hot fibers after the fiberization of a mineral wool, using a binder that comprises hydroxylamine or an amino alcohol with the following general formula (I) wherein R1 and R2 are the same or different from each other, and independently are hydrogen, a linear or branched, saturated or unsaturated aliphatic hydrocarbon with 1 -12 carbon atoms, a saturated or unsaturated alicyclic or heterocyclic hydrocarbon with 5-8 carbon atoms, a carbocyclic or heterocyclic aromatic hydrocarbon with 5 - 1 2 ring members or a chain-like or branched alyklether with 1 -50 alkoxy units or a chain-like or branched alkylamine with 1 -50 alkylamine units; and R3 is a linear or branched, saturated or unsaturated aliphatic hydrocarbon with 1-12 carbon atoms, a saturated or unsaturated alicyclic or heterocyclic hydrocarbon with 5-8 carbon atoms, a carbocyclic or heterocyclic aromatic hydrocarbon with 5-12 ring members or a chain-like or branched alkylether with 1 -50 alkoxy units or a chain-like or branched alkylamine with 1-50 alkylamine units.

02 Oct 2009TL;DR: In this article, a 1,3,5-triazine derivative is represented by the formula (1): wherein R1, R2 and R3 each independently represent a hydrogen atom or a methyl group; X represents a carbon atom or two nitrogen atoms; Ar1 represents a substituted or unsubstituted aromatic hydrocarbon group; Ar2 represents an C 1-4 alkyl-substitized 6-membered heterocyclic group, which may be a condensed ring compound.
Abstract: A 1,3,5-triazine derivative represented by the formula (1): wherein R1, R2 and R3 each independently represent a hydrogen atom or a methyl group; X represents a carbon atom or a nitrogen atom; Ar1 represents a substituted or unsubstituted aromatic hydrocarbon group; Ar2 represents an C1-4 alkyl-substituted or unsubstituted aromatic 6-membered heterocyclic group having one or two nitrogen atoms, which may be a condensed ring compound. An organic electroluminescent device comprising the 1,3,5-triazine derivative exhibits low power consumption and long lifetime.

TL;DR: In this article, a monocycloalkyl aromatic hydrocarbon is prepared by a hydroalkylation process in which an aromatic hydrocarbinear is contacted with hydrogen in the presence of a catalyst comprising ruthenium and nickel supported on zeolite beta.
Abstract: A monocycloalkyl aromatic hydrocarbon, e.g. cyclohexyl benzene, or a substituted monocycloalkyl aromatic hydrocarbon is prepared by a hydroalkylation process in which respectively an aromatic hydrocarbon, e.g. benzene, or an alkyl substituted aromatic hydrocarbon is contacted with hydrogen in the presence of a catalyst comprising ruthenium and nickel supported on zeolite beta. Optionally the catalyst can also include a rare earth metal, e.g. lanthanum.

TL;DR: An adsorptive separation process for separating tetra-alkyl substituted monocyclic aromatic isomers, the alkyl constituents containing from one to four carbon atoms each, from a feed mixture comprising at least two of the isomers was proposed in this article.
Abstract: An adsorptive separation process for separating tetra-alkyl substituted monocyclic aromatic isomers, the alkyl constituents containing from one to four carbon atoms each, from a feed mixture comprising at least two of the isomers, which process employs a crystalline aluminosilicate adsorbent containing a specific cation or cations at the exchangeable cationic sites to selectively adsorb a component of the feed mixture. A desorption step may then be used to desorb the adsorbed feed component. The process can be either in the liquid or vapor phase.
