摘要： PROBLEM TO BE SOLVED: To provide a method for producing a fluorescent substance precursor particle at a low cost which, because of the narrow particle size distribution and the sphericity, can be used for a cathode tube, a fluorescent lamp, a plasma display panel and a field emission display to form a uniform and minute fluorescent film having a high luminance, and moreover, because of the high purity and the homogeneity in chemical composition, can display an excellent fluorescence property; and a method for producing a fluorescent substance. SOLUTION: The method for producing a fluorescent substance precursor particle comprises reacting the raw material component for a fluorescent substance precursor, wherein the raw material component is passed through a mono-or multi-phase tubular reactor to react under a temperature and pressure condition below a certain critical point resulting in depositing the solid fluorescent raw material followed by obtaining continuously. The method for producing the fluorescent substance comprises further baking the fluorescent substance precursor particle thus obtained.

摘要： PROBLEM TO BE SOLVED: To obtain an aldehyde in a high yield, while inhibiting the deactivation of a catalyst, by reacting an olefinic compound with hydrogen and carbon monoxide in the presence of the rhodium complex catalyst containing an organic phosphite and then separating the produced aldehyde from a catalyst liquid containing the catalyst in a separation zone wherein a liquid contact portion is made from a metal material containing nickel. SOLUTION: This method for producing an aldehyde comprises reacting an olefinic compound (for example, propylene or 1-butene) with hydrogen and carbon monoxide in a solution containing a rhodium complex catalyst having an organic phosphite [for example, diphenyl(2,4-ditertiary butylphenyl)phosphite] as a ligand, separating the produced aldehyde from the reaction solution in a separation zone having a liquid contact portion, for example, by a distillation method, and then circulating the obtained catalyst liquid containing the rhodium complex catalyst to the reaction zone. Therein, the liquid contact portion is formed from a metal material containing nickel (for example, an austenite-based stainless steel containing >=>=8 wt.% of nickel).

摘要： PROBLEM TO BE SOLVED: To obtain an aldehyde in high yield while reducing the poisoning of catalyst and suppressing the lowering of the catalytic activity by separating the aldehyde in a separation process in a manner to leave a specific amount of the aldehyde in the catalyst liquid. SOLUTION: An olefinic compound (preferably propylene, 1-butene, 2-butene, etc.), is made to react with carbon monoxide and hydrogen in the presence of a rhodium complex catalyst containing an organic phosphite [preferably an organic phosphite of the formula (R1 to R3 are each a 1-30C hydrocarbon group or the like)] as a ligand to produce an aldehyde. The produced reaction liquid is taken out of the reaction zone and the aldehyde is separated from the liquid in such a manner as to keep the aldehyde concentration of >=0.5 wt.% (preferably 3.0-25 wt.%) in the catalyst liquid to obtain the catalyst liquid containing the rhodium complex catalyst. The separated catalyst liquid is circulated to the reaction zone. The process is effective for inhibiting the lowering of the catalytic activity and expected to enable the lowering of the catalyst poisoning.

摘要： PURPOSE:To provide a method for producing PTMG industrially and extremely advantageously, capable of obtaining especially middle molecular weight PTMG having a narrow molecular weight distribution of PTMG in high yield, readily recovering a catalyst in a batch reaction form and easily regenerating the catalyst in a circulation reaction method. CONSTITUTION:In a method for producing a polyoxyalkyelne glycol by ringopening polymerization of a cyclic ether, the characteristic of the method is to use a zeolite (except ZSM-5, ZSM-11 and Nu-5) as a catalyst. Tetrahydrofuran is especially used as the cyclic ether and is subjected to ring opening polymerization to provide the objective method for producing a polytetramethylene ether glycol. A new metalloaluminosilicate has a zeolite beta skeleton and comprises aluminum and/or silicon in the skeleton which is substituted in the same shape with at least one kind of metal selected from chromium, boron, lead, tin, copper, indium, cobalt, nickel, zinc, vanadium, molybdenum, arsenic, antimony, manganese, germanium, silver, lanthanide, cadmium, magnesium, cerium and phosphorus.
