Abstract: Process for destroying organic halogen compounds, which are contained in dust-containing gases which have a carbon content of less than 0.6% by weight, by oxidative degradation with the aid of fixed catalysts suitable for this purpose, characterised in that a) the dust is separated off at 250 to 500 DEG C from the gases and the dust-free gas together with oxygen or an oxygen-containing gas is passed over the catalyst, or b) the dust is separated off below 250 DEG C, the organic halogen compounds are desorbed from the dust in an oxygen-containing gas stream at 250 to 500 DEG C and the gas stream is passed over the catalyst, or c) the dust-containing gas is passed over the catalyst in the presence of oxygen at 250 to 500 DEG C and the dust is then separated off.

Abstract: Very pure 1,6-hexanediol is obtd. from a mixt. with other diols by opt. distilling out the light and heavy fractions and partially crystallising out crude alcohol mixt. by cooling to 42-15 degrees C, followed by sepn. of the crystals, washing with 1,6-hexanediol and recycling of the mother liquor obtd. after sepn. of the crystals to the crude alcohol mixt. prior to its distn. Purity is >99% as reqd. in the prepn. of plastics and esp. fibres.
