    摘要： The present invention provides a titanium-containing solution having excellent storage stability and containing the titanium component at a high concentration; a catalyst for polyester preparation exhibiting excellent supply uniformity and high catalyst performance, which does not have adverse effect on the quality of the aliphatic diols to be recovered and recycled; and a catalyst for polyester preparation having high catalyst activity and high molding stability. The invention also provides a process for preparation of a polyester resin using the catalyst, and a blow molded product comprising the polyester resin. A first embodiment of the invention is a titanium-containing solution which contains titanium, an aliphatic diol and a polyhydric alcohol having a valency of 3 or greater. A second embodiment of the invention is a titanium-containing solution which has the titanium particle size in the solution within a specific range.

    摘要： A method for preparing acrolein or methacrolein comprises subjecting propylene, secondary propanol, isobutylene or tertiary butanol to gas phase catalytic oxidation with molecular oxygen in the presence of a catalyst represented by the following general formula (I):Mo.sub.a Bi.sub.b Fe.sub.c X.sub.d Y.sub.O Z.sub.f O.sub.g (I)wherein X represents at least one element selected from the group consisting of Ni and Co; Y represents at least one element selected from the group consisting of K, Rb, Cs and Tl; and Z represents at least one element selected from the group consisting of Be, Mg, Ca, Sr, Ba, Ce, Ti, Zr, Nb, Cr, W, Mn, Cu, Ag, Zn, Cd, B, Al, Si, Ge, Sn, Pb, P, As, Sb, S, Se and Te; a, b, c, d, e, f and g each represents an atomic ratio of the corresponding element and when a is assumed to be 12, b=0.1.about.10, c=0.1.about.20, d=2.about.20, e=0.01.about.2, f=0.about.4 and g represents the number of oxygen atoms required for satisfying the valency requirement of the constituent elements, wherein the catalyst used is prepared by separately preparing solutions each of which contains the starting compound for the foregoing catalyst components, mixing these solutions within a short period of time, spray-drying the resulting mixture immediately after the mixing and then calcining the dried powder. A catalyst which further comprises 5 to 15% by weight of silica in addition to the foregoing composition is also used in the method. End products can be obtained in high conversion and selectivity through the use of the foregoing catalyst. Moreover, the catalyst is excellent in stability and has good reproducibility.
