Abstract: PROBLEM TO BE SOLVED: To provide a new method for industrially advantageously producing a glyoxal monoacetal, enabling to profitably obtain the glyoxal monoacetal by reacting glyoxal and a glyoxal bisacetal with an alcohol under a specific reaction condition. SOLUTION: This method for producing a glyoxal monoacetal of formula I (R , R are each a 1-4C alkyl, a 2-4C alkenyl) comprises reacting the mixture of glyoxal with a glyoxal bisacetal of formula II with an excessive amount of an alcohol of the formula: R OH or R OH or their mixture in the presence of an acidic catalyst until the equilibrium of the reaction is achieved. The acidic catalyst is preferably an acidic ion exchange material, especially preferably the fixed bed of the acidic ion exchange material. The alcohol is preferably methanol. The glyoxal bisacetal, the acidic catalyst and the alcohol are preferably reutilized for the reaction.

Abstract: The invention relates to a method for the continuous production of glutaraldehyde by reacting an alkoxydihydropyrane of general formula (I), wherein R represents C1-C20 alkyl, with water at a temperature in the range of from 0 DEG C to 2000 DEG C and a pressure in the range of from 0.01 bar to 16 bar, and obtaining glutaraldehyde and the alcohol that corresponds to the alkoxy group. Water and alkoxyhydropyrane are continuously fed to a reaction column and at the top of the column a distillate enriched with the alcohol that corresponds to the alkoxy group and at the foot thereof a product enriched with glutaraldehyde is removed. The inventive method provides a simple means for producing glutaraldehyde or C-substituted glutaraldehydes continuously and with an improved purity which requires a minimum of equipment.

Abstract: Continuous production of dimethyl vinyl carbinol (DMVC) comprises reaction of prenol with an aqueous solution of a protonic acid in the bottom or upper part of a rectification column while distilling off the DMVC as an azeotropic mixture with water under specified conditions. Continuous production of dimethyl vinyl carbinol (DMVC) by reaction of prenol with an aqueous solution of a protonic acid in the bottom or upper part of a rectification column while distilling off the DMVC as an azeotropic mixture with water is performed in such a way that (a) the amount of liquid two-phase mixture formed during the reaction is minimized, (b) the DMVC is distilled off with a reflux ratio of at least 2, and (c) the reaction volume (V in ml) and/or the amount of prenol added per hour (P in ml/hour) and/or the proton concentration in the reaction mixture (C in moles/liter) is such that VC/P = 0.001-1 h.mol/l.
