Abstract: An improved process for the production of Alpha chlorocarboxylic acid chlorides by reaction of a carboxylic acid chloride with chlorine at elevated temperature, wherein the improvement consists in carrying out the reaction in the presence of sulfuric acid. Alpha -chlorocarboxylic acid chlorides are suitable for the production of plant protection agents.

Abstract: Alkanols of formula R1-CH(OH)-CH(R3)-R2 (I) are prepd. by reacting a sec. alcohol of formula R1-CH(OH)-CH2(R3) (II) with a prim. alcohol of formula R2OH, in presence of an alkali hydroxide at 150-300 deg.C; R1 = aromatic or heterocyclic gp.; R2 = 1-20C alkyl; R3 = H, Me or Et. Pref. reaction is at 200-300 deg.C, using KOH; R1 is pref. phenyl, opt. carrying 1-4C alkyl gp(s). The sec. alcohol may contain a pyridyl gp. as heterocyclic gp.

Abstract: Process for the preparation of 3-aryl-isobutanols of the general formula I … … in which… R and R are hydrogen or an alkyl or cycloalkyl radical with up to 8 C atoms, preferably an alkyl radical with 1 to 4 C atoms,… which is characterised in that arylcarbinols of the general formula II … … are reacted with n-propanol in the presence of catalytic amounts of an alkali metal hydroxide or alkali metal oxide at 250 to 350 DEG C in a closed reaction vessel. … The process is particularly important for preparing 3-aryl-isobutanols of the formula I in which R is an alkyl radical with 1 to 4 C atoms and R is hydrogen. The p-methyl-, p-isopropyl- and p-tert.-butylphenylisobutanols obtained in this way in very high selectivity are valuable precursors for the fragrances jasmorange, cyclamenaldehyde and Lysmeral (Lilial ) which are in high demand.

Abstract: In a process for preparing phthalic anhydride by catalytic gas-phase oxidation of o-xylene or naphthalene or o-xylene/naphthalene mixtures with a gas comprising molecular oxygen over a coated catalyst comprising an inert, nonporous support material on which a catalytically active composition comprising titanium dioxide and vanadium pentoxide is applied in layer form, a catalyst whose catalytically active composition comprises from 3 to 6% by weight of vanadium pentoxide, calculated as V2O5, from 0.3 to 0.5% by weight of a cesium compound, calculated as Cs, and the remainder to 100% by weight of titanium dioxide in the anatase modification is used in the presence or absence of a coated catalyst, differing therefrom, for the catalytic gas-phase oxidation of o-xylene or naphthalene or o-xylene/naphthalene mixtures and, in the presence of such a second catalyst, the latter is used in a combined bed with the catalyst of the above composition in the reactor.
