Abstract: A catalyst tablet (I) comprises an inorganic titania (TiO2)-containing support and copper as the active component, optionally with zinc, aluminum, cerium and a Group 8 metal. The copper surface area is up to 10 m /g. The tablet has a diameter d and/or height h of less than 3 mm. An Independent claim is also included for catalytic hydrogenation of carbonyl compound(s) in the presence of the catalyst tablets (I).

Abstract: A process for improving the color number of polyhydric alcohols (I), especially trimethylolpropane (TMP), involves catalytic hydrogenation of (I), which is purified by distillation after production. Hydrogenation is carried out in the presence of a macroporous, supported heterogeneous catalyst containing sub-group VII-X metal(s) as the active metal.

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: The invention relates to a method for the removal of trihydroxymethylpropyl formate from trihydroxymethylpropane, as produced by the hydrogenation of a 2,2-dimethylalkanal. An effective removal of said formate may be achieved by drying the raw solution of trihydroxymethylpropane, obtained from the hydrogenation and addition of ammonia, or primary and secondary amines in anhydrous form.

Abstract: The invention relates to a method, whereby the colour number of polyhydric alcohols, in particular, trihydroxymethylpropane, can be significantly improved by hydrogenation. The method is characterized in that an alcohol is used in the hydrogenation, which has been previously purified by distillatio n. The conventional catalysts for hydrogenation are used as catalysts, preferab ly copper, nickel, palladium or ruthenium.
