Abstract: A process for preparing alkanols (I) selected from the group consisting o f isopropanol and 2-butanol from the corresponding alkanes (II) selected fro m the group consisting of propane and n-butane, comprising the steps of: A) a use gas stream a comprising the alkane (II) is provided; B) use gas stream a comprising the alkane (II) is fed into a dehydrogenation zone and the alk ane (II) is subjected to a dehydrogenation to the alkene (III), to obtain a product gas stream b comprising the alkene (III), unconverted alkane (II), w ith or without high boilers, steam, hydrogen and low boilers; C) product gas stream b is at least compressed, and product gas stream b is optionally sep arated into an aqueous phase c1, a phase c2 which comprises the alkene (III) and the alkane (II), with or without high boilers, and a gas phase c3 compr ising hydrogen and low boilers; D) product gas stream b or the phase c2 comp rising alkene (III) and alkane (II) is reacted in an esterification zone wit h an organic acid (IV) to obtain a product mixture d comprising the correspo nding alkyl ester (V) of the organic acid and the unconverted alkane (II); E ) a gas stream e1 comprising alkane (II) is removed from the product mixture d and is optionally recycled into the dehydrogenation zone, and a product m ixture e2 comprising the alkyl ester is obtained; F) product mixture e2 comp rising the alkyl ester is reacted in a deesterification zone with water to g ive a product mixture f comprising the alkanol (I) and the organic acid (IV) ; G) the alkanol (I) and the organic acid (IV) are removed from the product mixture f, and the organic acid is optionally recycled into the esterificati on zone.

Abstract: Synthesis of olefin from synthesis gas in the presence of at least a Fischer-Tropsch catalyst in a reaction column comprises introducing the synthesis gas into the beneath of the zone (A) of the reaction column and removing the obtained olefin from the beneath of the inlet for the synthesis gas. An independent claim is included for a mixture of olefin obtained by the above process.

Abstract: Precipitation method involves utilizing a non-polar solvent or solvent mixtures. The solution is removed with a polar solvent selectrd from hydroxyl group containing compound, has a general formula (I) and carbonyl group containing compound has general formula (II). The precipitated polymer is isolated. A replacement with the polar solvents and the separation of volatile solution components from the polymers are carried out by degassing in a stirred tank, kneading machine, thin film vaporizer, falling film evaporator or coil tube evaporator. The hydroxyl group containing compound having general formula (I), is R1>(O-A)n-OH. R1>H, 2-20C alkyl or alkenyl residue, 5-20C cycloalkyl residue or 6-20C aryl, alkyl aryl or aryl alkyl residue; A : 2-4C alkylene; and n : 0-10. The carbonyl group containing compound having general formula (II) is R2>-CO-X-R3>. R2>H, 2-20C alkyl or alkenyl residue, 5-20C cycloalkyl residue or 6-20C aryl, alkylaryl or arylalkyl residue; X : S or O and R3>2-20C alkyl or alkenyl residue, 5-20C cycloalkyl residue or 6-20C aryl, alkylaryl or arylalkyl residue.
