Abstract: PROBLEM TO BE SOLVED: To prevent spontaneous decomposition of acetylene gas or gas mixture containing the same in a chemical reactor, by treating an area of the reactor where the decomposition begins, with an inert oil having a medium viscosity. SOLUTION: The spontaneous decomposition is prevented by formulating/ introducing an inert oil (e.g. liquid paraffin, synthetic oil such as polyolefin oil) having a viscosity of 1-100 mm /sec at 100 deg.C, continuously or in a batch method, forming oil mist, together with acetylene gas having a partial pressure of 2 bar or higher and a temperature of 50 deg.C or higher, at least to the part of the reactor where the decomposition begins, especially where chemically igniting matter deposits, at a rate of 1-100 ml kg -acetylene hr .

Abstract: The invention relates to a method for obtaining pure N-vinyl pyrrolidone from raw materials containing N-vinyl pyrrolidone, said method comprising a single or multiple-stage crystallisation method. The method is characterised in that the mother liquor of the first crystallisation stage is either purified by distillation and/or extraction or is returned to a product stream of the production process, said stream containing an N-vinyl pyrrolidone.

Abstract: Alcohols are prepared by the catalytic hydrogenation of the corresponding carbonyl compounds at elevated temperatures and at superatmospheric pressure in the liquid phase by a process in which the catalyst used contains copper on an SiO2-containing carrier in the presence or absence of one or more of the elements magnesium, barium, zinc and chromium.

Abstract: The prepn. of monovinyl ethers of formula (I), comprises reacting a diol of formula (II) with C2H2 in the presence of a base. The reaction is carried out at 150-250 degrees C and an C2H2 partial pressure of 5-25 bar until the diol conversion is 40-80%, then the reaction is stopped and (I) is isolated. In (I) and (II): A = a chemical bond, -CH2- or -CH2CH2-; R , R = H, (cyclo)alkyl or aryl; or R R = a 3-5C alkylene bridge.
