| 20100105957 | PROCESS FOR PRODUCING ACROLEIN AND GLYCERIN-CONTAINING COMPOSITION - The present invention provides a process for producing acrolein, which exhibits a prolonged catalyst life, low energy consumption, and excellent efficiency, and which is earth-conscious, and a glycerin-containing composition which can preferably be used even in this process. The process for producing acrolein is one which includes bringing a raw material gas containing glycerin gas into contact with a solid acid catalyst in a reactor, and the partial pressure of the glycerin gas in the raw material gas is set to be from 0.01 to 30 kPa. The glycerin-containing composition is for use in a process for producing acrolein using a solid catalyst and includes a fatty acid and/or a fatty acid ester, and a total mass of the fatty acid and the fatty acid ester is from 0.001% to 5% by mass, relative to the glycerin. | 04-29-2010 |

| 20090118549 | Process for Production of Acrolein - There is provided a process for producing acrolein from glycerin, exhibiting a suppressed decrease in the yield of acrolein with time. In the process for producing acrolein by dehydrating glycerin in the presence of a catalyst containing a metal phosphate, one, or two or more, metal phosphates are used, which are selected from aluminum salts, zirconium salts, manganese salts, alkali metal salts (provided that the alkali metal is sodium, potassium, or cesium, and the ratio between the mole number (M) of the alkali metal and the mole number (P) of phosphoric acid (i.e., M/P ratio) in the metal phosphate is 2.0 or lower), alkali earth metal salts (provided that the ratio between the mole number (M) of the alkali earth metal and the mole number (P) of phosphoric acid (i.e., M/P ratio) in the metal phosphate is 1.0 or lower), and the like. | 05-07-2009 |

| 20110257355 | Process for producing acrylic acid - A process for producing acrylic acid of the present invention comprises the step of conducting gas-phase oxidative dehydrogenation of a composition containing propionaldehyde using a solid catalyst containing molybdenum and vanadium as essential components, thereby obtaining acrylic acid. The obtained acrylic acid is preferably purified by crystallization, and a monomeric component containing the purified acrylic acid is polymerized to thereby give a hydrophilic resin such as an absorbent resin and a water-soluble resin. | 10-20-2011 |

| 20100113838 | PROCESS FOR PRODUCING ACROLEIN - There is provided a process for producing acrolein, which makes it possible to obtain acrolein in high yield by dehydration of glycerin. Glycerin is allowed to coexist with a catalyst containing a rare earth metal salt crystal of phosphoric acid, thereby dehydrating the glycerin, wherein the crystal is obtained by calcining a solid which is formed by allowing a liquid containing water and a hydroxide of the rare earth metal and/or a dehydration condensate of the hydroxide to contain phosphate ions. | 05-06-2010 |

| 20100129948 | METHOD FOR MANUFACTURING SEMICONDUCTOR SUBSTRATE AND METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE - An object is to manufacture a semiconductor substrate having a single crystal semiconductor layer with favorable characteristics, without requiring CMP treatment and/or heat treatment at high temperature. In addition, another object is to improve productivity of semiconductor substrates. Vapor-phase epitaxial growth is performed by using a first single crystal semiconductor layer provided over a first substrate as a seed layer, whereby a second single crystal semiconductor layer is formed over the first single crystal semiconductor layer, and separation is performed at an interface of the both layers. Thus, the second single crystal semiconductor layer is transferred to the second substrate to provide a semiconductor substrate, and the semiconductor substrate is reused by performing laser light treatment on the seed layer. | 05-27-2010 |
