Abstract: The invention provides a process for preparing polyester polyols of polyhydric alcohols by mono- or polyesterification of at least one carboxylic acid having at least two acid groups and/or at least one derivative of a dicarboxylic acid with polyhydric alcohols, optionally with the addition of a catalyst, while removing the water of reaction, wherein the polyhydric alcohol used has a formaldehyde acetal content of less than 500 ppm.

Abstract: The invention provides novel mepiquat plant growth regulator compositions which have improved hygroscopicity and corrosion characteristics. The novel mepiquat plant growth regulator compositions of the invention can be readily prepared from technical mepiquat chlorid inter alia by electrochemical ion exchange processes or by quaternization of N-methylpiperidine with dimethylcarbonate as starting material.

Abstract: Trimethylol propane is isolated from a reaction mixture, obtained by reaction of n-butyraldehyde with formaldehyde in the presence of a base and optional hydrogenation of the mixture obtained. The mixture is distilled using a partition column or a distillation column with a pre-column or a distillation column with a post-column. The method is characterised by a low investment and energy cost and the reduced formation of high-boiling by-products.

Abstract: The invention relates to a method for removing acetals containing formaldehy de from polyvalent alcohols, especially trimethylolpropane. The inventive metho d is characterised in that the polyvalent alcohol is liberated of low-boiling constituents after it has been produced by distillation, is then subjected t o tempering and is repurified, preferably by means of distillation.
