Abstract: Racemic pantolactone is resolved by sepn. of the salts of pentanoic acid with (-) or (+)-3-aminomethylpinane followed by reformation of the lactone. D(-) Pantolactone is converted into D(+) pantothenic acid D(+) panthenol and D(+) panthetine.

Abstract: Radiation-hardenable coating and impregnating compsns. contain, as binder-forming components, unsatd. polyesters (I) contg. the grouping -OCH2-CH(-CH=CH2)-O- (I) are opt. mixed with olefinically unsatd. copolymerisable cpd(s) and opt. further standard additives for lacquer industry. (I) have a high hardening activity and can be hardened with a low radiation dosage to give scratch-proof hard to elastic light-coloured coatings adhering well to substrates.

Abstract: Cyclohexane-1,3-dione derivatives of the formula I I where R1 is cycloalkyl of 3 to 12 carbon atoms which may or may not be olefinically monounsaturated to tetraunsaturated, can be substituted by not more than 3 methyl or ethyl groups, one vinyl, methylvinyl or allyl group, 1 or 2 chlorine atoms or one alkoxy group of 1 to 4 carbon atoms and can be bridged by an alkylene chain of not more than 4 carbon atoms, X is alkylene of 1 to 5 carbon atoms, which can be monounsaturated or diunsaturated, interrupted by not more than 2 sulfur or oxygen atoms and substituted by not more than 3 alkyl groups of 1 to 3 carbon atoms, R2 is hydrogen of alkoxycarbonyl where alkoxy is of 1 to 2 carbon atoms, R3 is alkyl of 1 to 4 carbon atoms, R4 is alkyl of 1 to 3 carbon atoms, alkenyl of 3 or 4 carbon atoms, propargyl or haloalkenyl of 3 or 4 carbon atoms and 1 to 3 halogen atoms, and the salts of these compounds, processes for their preparation, herbicides containing these compounds, and their use.

Abstract: New tetrahydropyran derivs. have formula (I) (where one A gp. is aminomethyl and the other A gps. are H). (I) are intermediates for prepn. of new anthraquinoid dispersion dyes having formula (II) (where X is H, Cl or Br and Y is the organic gp. of (I). (II) are fast on synthetic, esp. polyester, fabrics. Examples describe prepn. of 3-formyl-4-Me-, 4-formly-4-Me- and 4-(2-formylmethyl)-tetrahydropyran isomer mixt. by hydroformylation of 4-Me-2,3-dihydro-6H-pyran, and aminating hydrogenation of aldehydes obtd.

Abstract: In prepn. of 1,3-dihydroxyacetone esters of formula R1O-ch2-CO-CH2-OR2 (I), 2-methlene-1,3-propanediol esters R1O-CH2-C(=CH2)-CH2-O-COR2 (II) are reacted with ozone and the reaction mixt. formed is reacted with a reducing agent. In formulae (I) and (II), R1 is H or the residue -CO-R3; and R2 and R3 are each H or a (cyclo)aliphatic, araliphatic or aromatic residue. (I) and the dihydroxyacetone into which they can be converted by their basic hydrolysis are useful as intermediates for dyes, pharmaceuticals, plant-protection agents and cosmetics. Dihydroxyacetone is useful as a mild reducing agent for vat dyeing and as an artificial skin-browning agent in cosmetics. The process is simpler and more economical than known chemical methods for the prodn. of dihydroxyacetone (esters).
