Abstract: Polyester is produced by reaction of an aliphatic dicarboxylic acid, neopentyl glycol, at least one other diol, and a nonanol mixture comprising mainly 1-nonanol, monomethyloctanols, dimethylheptanols and monoethylheptanols. An Independent claim is also included for the nonanol mixture.

Abstract: Pure monoesters of adipic acid are prepared by a process in which (a) a pentenoate is reacted with carbon monoxide and hydrogen at from 90 DEG to 140 DEG C. and under from 5 to 300 bar in the presence of a carbonyl complex of cobalt or of rhodium, and a 5-formylvalerate is separated off, and (b) the 5-formylvalerate thus obtained is oxidized with molecular oxygen, or with a gas containing this, at from 20 DEG to 100 DEG C. under from 1 to 10 bar.

Abstract: The invention relates to a process for the preparation of compounds of the formula I in which X and Y independently of one another are fluorine, chlorine or bromine and one of the radicals can also be hydrogen, characterised in that compounds of the formula II are oxidised with nitric acid at elevated temperature and elevated pressure to give compounds of the formula III and these are isolated and freed from nitric acid and then hydrogenated under mild conditions to give the compounds of the formula I. The compounds of the formula I are highly suitable, for example, as diazo components.
