Abstract: The invention relates to novel phenothiazine derivatives, to a process for their preparation, and in particular to the use of phenothiazine derivatives, preferably liquid at 20 DEG C, of the formula in which R and R are identical or different and are hydrogen, halogen, an alkyl, alkoxy or alkylmercapto group having 1 to 18 carbon atoms, or an optionally substituted phenyl radical, R is hydrogen or a methyl, ethyl and/or methylol radical, n is an integer from 1 to 20, and m is an integer from 3 to 12, as stabilisers, preferably against UV radiation and thermal degradation, for plastics prepared by the polyisocyanate polyaddition process, preferably compact or cellular polyurethane polyurea elastomers.

Abstract: The invention concerns the use, as anti-foaming agents in the paper industry, of alkoxylated amines or alkoxylated polyamines which each contain random ethylene oxide and propylene oxide blocks or ethylene oxide and propylene oxide units, the molar ratio of the ethylene oxide to the propylene oxide units being 1:4 to 1:20. The invention also concerns anti-foaming agents containing such alkoxylated amines and/or alkoxylated polyamines, at least one emulsifier with an HLB value of at least 8 and, optionally, up to 90 % by wt. of water.

Abstract: Hydroxy mixed ethers are claimed which are obtd. by ring-opening reaction of unsatd. fatty acid ester epoxides (I) with polyglycol ethers of formula R1-O-(CH2.CHR2.O)n-H (II) in presence of Lewis acids with exclusion of protons (where, R1 = H, 1-30C alkyl or 8-30C alkenyl; R2 = H, Me or Et; and n = 1-50 (R1 not = H) or 2-50 (R1 = H)).

Abstract: Process includes catalytically converting substrates with ethylene oxide in a reactor. After a predetermined amt. of ethylene oxide has been supplied to the reactor, the supply line is emptied by blowing it through with N2. The supply line is then closed off and a connection line, between the ethylene oxide line and an exhaust gas torch, is opened. ADVANTAGE - The process ensures that ethylene oxide cannot flow back into the reactor after the reaction is complete

Abstract: A mixture is disclosed of at least two alkoxylated alcohols and having the formula (I), in which x is a number between 1 and 12 and y is a number between 1 and 15. One alkoxylated alcohol has as residue R a straight-chain or branched-chain C8-C18-alkyl group and the other alkoxylated alcohol has as residue R a straight-chain or branched-chain C10-C20-alkyl group, but the average number of C atoms in the residues R must differ by at least 0.5, whereas the ratio between both alkoxylated alcohols is comprised between 10 : 90 and 90 : 10. This mixture is suitable as an antifoam tenside additive in cleaning products for machine washing processes.

Abstract: The parent patent describes a method of carrying out exothermic reactions between a gas and liq in the presence of solid catalysts; the gas and liq pass in parallel flow through a long reaction vessel contg packing, the quantity of liq passed through the vessel being such that, with const gas flow the increase in press difference between the vessel ends is >=2- fold, but the fluctuations in press difference normally caused by pulsation are eliminated. In the Patent of Addition, the method is applied to reactions which do not take place in the presence of solid catalysts, but which occur spontaneously or in the presence of dissolved or finely suspended catalysts, opt without special heat conditioning; instead of the catalyst, any kind of packing is used for the reaction vessel.
