Abstract: The hydrogenation of esters of benzene-dicarboxylic acids is carried out on supported catalysts containing a Sub-Group VIIII metal on a macroporous support. A process for the hydrogenation of benzene-dicarboxylic acid ester(s) with hydrogen in presence of a supported catalyst containing Sub-Group VIII metal(s) on a macroporous support. If the ester is dimethyl terephthalate, this excludes hydrogenation on a catalyst containing ruthenium, with or without Sub-Group I, VII or VIII metal(s), on a support with an average pore diameter (APD) of at least 50 nm and a BET surface of not more than 30 m /g, with an active metal content of 0.01-30 wt.% and a ratio of (active metal surface):(support surface) of less than 0.05, and/or on a catalyst containing 0.01-30 wt.% active metal(s) as above on a support in which 10-50 vol.% of the pores consist of macropores with a diameter of 50-10,000 nm and 50-90 vol.% consist of mesopores with a diameter of 2-50 nm.

Abstract: The novel compound 2-neo-pentylanthraquinone, which is prepared by Friedel-Crafts acylation of neopentylbenzene with phthalic anhydride followed by cyclization of the resulting 2-(4-neopentyl-benzoyl)-benzoic acid in the presence of a strong, anhydrous acid, is a catalyst for the preparation of hydrogen peroxide.

Abstract: The invention relates to a method for producing vinyl phosphonic acid compounds of general formula (I) wherein R1 and R2 are independently H, C1-16-aryl, C7-12-alkaryl or C7-12-aralkyl radicals, wherein the organic radicals can be substituted by one or several halogen atoms, hydroxyl, acyl or acetoxy groups. Production occurs by reacting phosphoric acid compounds of general formula (II) with acetylene in the presence of a Pd(II) complex and/or a Pd(0) complex or corresponding Pt complexes as a catalyst.

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.

Abstract: Disclosed is a method for the preparation of formyltetrahydropyrans (I) by dehydrogenating hydroxymethyltetrahydropyrans (II) in the presence of a copper, silver and/or gold catalyst. The formyltetrahydropyrans (I) thus obtained are useful intermediates in the preparation of pharmaceuticals and phytopathalogical products.
