Abstract: In the present invention there is disclosed a reaction product of polyisobutenes with nitrogen oxides or a mixture of nitrogen oxides and oxygen of a derivative thereof, whereby the polyisobutene average degree of polymerization P ranged within 10 to 100 and a content E is in the range of from 60 to 90 percent of double bonds which can react with maleic anhydride, whereby the value E = 100 percent corresponds to the theoretical value for the case where each molecule of the polyisobutene has such a reactive double bond. The obtained reaction product is suitable as additive for fuels, in particular for compression ignition engines, and for lubricants. There is further described a process for preparing such reaction product as well as its use as an additive or a lubricant.

Abstract: Process for the preparation of cis-2-(1H-1,2,4-triazol-1-ylmethyl)-2-(halophenyl)-3-(halophenyl)oxira ne I by epoxidation of Z-3-(1H-1,2,4-triazol-1-yl)-2-(halophenyl)-1-(halophenyl)propene II, in which halogen is in each case fluorine, chlorine or bromine, by reaction of the crude epoxidation product with one or more reducing agents, in which the reducing agent is added to the reaction mixture in a substantially higher amount than is necessary for destroying any peroxide compounds present.

Abstract: Prepn. of 4,41-diaminobenzhydrols of formula (I) is effected by reaching 4,41-diaminobenzophenones of formula (II) with H2 at -20 to 100 deg.C/0.5-100 bar in presence of a hydrogenation catalyst and 0-20 mol. equivs. (based on (II)) of an acid and/or salt (e.g. H2SO4, HCl, H3PO4 or NaH sulphate) A = 1,4-phenylene opt. substd. by 1-12C alkyl and/or 1-12C alkoxy' R1 and R2 = H, 1-20C alkyl, 3-8C cycloalkyl, 7-12C aralkyl, aryl (opt. substd. by 1-12C alkyl and/or 1-12C alkoxy), 2-8C omego-hydroxyalkyl, (CH2.CH(R3).O)n CH2.CH(R3)OR4 or 2-7C alkylene (opt. substd. by 1-12C alkyl and opt. interrupted by -O-, -S- or -N(R4)-); R3 = H or Me; R4 = H or 1-20C alkyl; and n = 0-40. Pref. the catalyst is a Pd-contg. catalyst and is used together with 0.001-20 (esp. 0.5-10) mol. equivs. (based on (II)) of an acid. USE/ADVANTAGE - (I) are intermediates for di- and tri-aminotriphenylmethane dyes as well as for inks such as crystal violet lactares, levio-auramines or sulphinates. They are obtd. without the flammability, waste disposal and toxicity problems.

Abstract: O,N-Disubstituted hydroxylamines are prepared by reacting O-substituted ketoximes with hydrogen in the presence of a platinum catalyst at from 35 to 50 bar, in a medium containing a mineral acid. The O,N-disubstituted hydroxylamines I obtained by the process of the invention are valuable starting materials for the preparation of dyes, crop protection agents and drugs.
