Abstract: The invention relates to a method for catalytically hydrogenating carboxylic acids or the anhydrides or esters thereof into alcohol on heterogeneous catalysts containing hydrogenating elements of groups 6, 7, 8, 9, 10 and 11 and optionally groups 2, 14 and 15 of the periodic table of elements or consisting thereof, in a liquid phase at temperatures of 100-300 DEG C and at pressures of 10-300 bars, whereby 1-3,000 ppm of a basic alkali or earth-alkaline compound in relation to the liquid hydrogenating feed and selected from a group consisting of hydroxides, carbonates, carboxylates and alcoholates is added to the hydrogenating reaction mixture.

Abstract: Gas phase dehydration of butan-1,4-diol (I) to gamma -butyrolactone (II) is carried out in the presence of a catalyst (III) containing copper (Cu), which contains 4-40 wt.% Cu and 0-5 wt.% sodium oxide (Na2O) on a support of 80-100 wt.% silica (SiO2) and 0-20 wt.% calcium oxide (CaO). Also claimed is catalyst (III) per se.

Abstract: Prodn. of a thiazole ylid cpd. (A) comprises reacting a thiazoline cpd. (I) of formula (Ia)-(If) with at least one oxidising agent. Q = a gp. of formula (i); R1 = alkyl, cycloalkyl, aryl or alkylaryl (all with up to 30C, all opt. unsatd., all opt. substd. with one or more halo, OH, 1-8C alkoxy, 1-8C alkylthio, NO2, acylamino, and SO3H); R2-R9 = H or as R1; one of R2+R3, R3+R4, R4+R5, R5+R6, R6+R7 = A; A = 1-30C hydrocarbyl structure, opt. forming more than 1 ring (opt. substd. by 1 or more halo, OH and alkoxy); R = (CH2)n, 1,2-phenylene or a gp. of formula (a); provided R3+R4 is not A in (Ib) or (Ie). Also claimed is a process for the prodn. of dihydroxyacetone (DHA) by the thiazole ylid catalysed condensation of formaldehyde, by carrying out the prodn. of (A), and adding formaldehyde before, during or after the prodn. of (A).
