    摘要： Pure tert.-olefins are prepared from mixtures of hydrocarbons, which contain at least one such tert.-olefin, by reaction with an alkanol to give the corresponding alkyl tert.-alkyl ethers, and subsequent cleavage of these ethers back to the corresponding pure tert.-olefins and the alkanol, and the separation of the pure tert.-olefin from the alkanol. For this, the alkanol present after the cleavage of the ether is separated from the tert.-olefin to the extent of 60 to 99% by weight by distillation, and the residual amount of alcohol in the olefin fraction is removed by adsorption from this fraction onto a synthetic ion exchanger as an absorber resin. The admixture of the alkanol to the mixture of hydrocarbons with at least one tert.-olefin is carried out partly by using the alkanol fraction arising from the separating off of the pure tert.-olefin, and partly by desorption of the alkanol from the absorber resin with the aid of the mixture of hydrocarbons containing at least 1 tert.-olefin.

    摘要： A device for emission-free sampling of volatile liquids comprises a 4-way tap from which lead two lines, which can be connected together, from and to the container holding the liquid to be tested and two other lines, which can also be connected together, lead to a sample bottle which can be sealed and which can be connected to the device. The device further comprises a supply line for an inert flushing medium, which joins the line leading into the sample bottle in the region of the sample bottle, and a discharge line for the inert flushing medium, which leads from the line coming out of the sample bottle in the region of the sample bottle and proceeds to a disposal system.

    摘要： Cyclopentane and/or cyclopentene and, if desired, isopentane can be obtained by distillative separation from a pre-benzene fraction or a C5 fraction which has in each case being partially hydrogenated to remove acetylene compounds and diolefins, wherein a) in a first fractional distillation, low boilers are removed as first top product and, either b1) the first bottom product is fed to a second fractional distillation and there cyclopentene is taken off as second top product and cyclopentane and higher-boiling hydrocarbons are taken off as second bottom product and this second bottom product is separated into cyclopentene and higher boilers in a third fractional distillation, or b2) the first bottom product is subjected to a catalytic hydrogenation and subsequently, in a fractional distillation, separated into cyclopentane as top product and higher boilers as bottom product, or b3) the first bottom product is subjected to a fractional distillation to separate off the relatively high boilers as bottom product and the top product is subjected to a catalytic hydrogenation to form cyclopentene.

    摘要： The ammonium sulphate contained in tar-rich waste streams from the production of (meth)acrylonitrile can be precipitated out by adding 1 to 30 times the amount by weight of methanol, relative to the water content of the waste stream, and additionally 0.05 to 10% the amount by weight of ammonia, relative to methanol, to such a waste stream at 10.degree.-60.degree. C. and separating off the ammonium sulphate which precipitates out. The waste stream remaining after separating off the ammonium sulphate can, for example, be disposed of as low-sulphur waste-fuel in a combustion chamber.
