    摘要： A method for easily and inexpensively producing and purifying a fluoroaryl metal compound such as bis(pentafluorophenyl)dialkyltin which is less colored and has no impurities is provided. Hydrocarbon magnesium halide is reacted with fluoroaryl halide in a solvent including an ether solvent so as to obtain fluoroaryl magnesium halide, which is then reacted with an organic metal compound so as to produce a fluoroaryl metal compound. Tin is more preferable as a metal atom included in the organic metal compound. As for the ether solvent, chain ether solvents are preferable, more specifically, diisopropyl ether, dibutyl ether, and t-butylmethyl ether are more preferable. Besides, it is preferable that magnesium halide, which is a by-product of the fluoroaryl metal compound, is precipitated and removed, or treated with an acid.

    摘要： 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.

    摘要： After a fluoroaryl borane derivative is precipitated from a solution containing the fluoroaryl borane derivative, a bis (fluoroaryl) borane derivative, and a hydrocarbon solvent and is subjected to first filtration so that the fluoroaryl borane derivative is isolated, a filtrate that has been obtained by the first filtration is cooled and the bis (fluoroaryl) borane derivative is separated and is subjected to second filtration so that the bis (fluoroaryl) borane derivative is isolated. In a case where the solution contains fluorobenzene, the solution is concentrated, so that the fluorobenzene is removed. Thus, it is possible to provide the high-purity fluoroaryl borane derivative and bis (fluoroaryl) borane derivative having no impurity with ease and at a low cost.
