Title
Synthesis of 3-buten-1-ol from 1,4-butanediol over indium oxide
Abstract

Dehydration of 1,4-butanediol (14BDO) was investigated over indium oxide. Over the indium oxide prepared by precipitation, both conversion of 14BDO and selectivity to unsaturated alcohol, 3-buten-1-ol (3B1ol), increase with the increase in calcination temperature of indium oxide irrespective of the decrease in the specific surface area. The maximum values of 79.6% conversion and 79.0% selectivity to 3B1ol are obtained over indium oxide calcined at 900 °C. The values are much higher than the activities of commercial indium oxide. The activities of indium oxide depend on the shape of particles. Indium oxides prepared by the precipitation are composed of particles with diameter of 10–70 nm. The size and shape of particles change by calcination: spherical shape at low temperature of <800 °C varies to angular one at >800 °C with a slight growth of particle size. The change in the shape of the particles means that indium oxide crystallites calcined at >800 °C mainly expose 2 2 2 facets. The dehydration reaction of 14BDO to 3B1ol is preferentially promoted over 2 2 2 surface of bixbyite structure.

Graphical abstractIndium oxide prepared by precipitation and calcined over 800 °C is composed of octahedral crystallites surrounded by 2 2 2 facets. It shows excellent activity in partial dehydration of 1,4-butanediol to 3-buten-1-ol.Figure optionsDownload full-size imageDownload high-quality image (126 K)Download as PowerPoint slide
