Abstract: Morpholine and other cyclic imines are obtained by reacting diethylene glycol and other appropriate diols with ammonia under hydrogenating conditions in the gas phase in the presence of a catalyst which contains copper, a smaller amount of nickel and alumina.

Abstract: Pigment printing pastes contain thickeners binders, water and opt. emulsifiers, with the addn. of 0.1-1 wt. % methylolated aminoplast constituents, whose methylol gps. are >=50 mol. % etherified, >=20 mol. % being etherified with 10-30C alcohols and/or phenols. The pastes are used for natural and/or synthetic textiles, esp. cellulose fibres. Use of high viscosity petrol-in-water emulsions as thickeners is completely eliminated, while retaining the soft feed, brilliance of print and resistance of the print to mechanical stresses.

Abstract: Prepn. of 2-methyl-2-penten-1-al (I) is carried out by converting propionaldehyde (II) to 2-methyl-3-hydroxypentan-1-al and then to (I) in the presence of an aq. non-volatile alkali. The improvement comprises continuing the reaction until substantially all the (II) has disappeared, and then immediately dehydrating the resulting 2-phase reaction mixt. (I) is useful as an intermediate for pharmaceuticals, plasticisers, fibre raw materials and auxiliaries. The process gives 97-99% yields without intermediate sepn. of the organic phase (c.f. US 3432557). It is esp. suitable for continuous operation.
