Abstract:
1. A process for preparing an alkanol (I) from its corresponding alkane (II), comprising: A) providing a starting gas stream (a) comprising said alkane (II); B) feeding said starting gas stream (a) into a dehydrogenation zone and dehydrogenating said alkane (II) to its correspending alkene (III) to obtain a product gas stream (b) comprising said alkene (III), unconverted alkane (II), steam, hydrogen, and low boilers, and optionally high boilers; C) compressing said product gas stream (b) and optionally separating said product gas stream (b) into an aqueous phase (c D) reacting said product gas stream (b) or said phase (c E) removing from said product mixture (d) a gas stream (e F) reacting said product mixture (e G) removing said alkanol (I) and said organic acid (IV) from said product mixture (f) and optionally recycling said organic acid (IV) into said esterification zone; wherein said alkanol (I) is selected from the group consisting of isopropanol and 2-butanol; wherein when said alkanol (I) is isopropanol, its corresponding alkane (II) is propane and when said alkanol (I) is 2-butanol, its corresponding alkane (II) is n-butane; and wherein when said alkane (II) is propane, its corresponding alkene (III) is propene and when said alkane is n-butane, its corresponding alkene (III) are butenes.
