摘要:The present application discloses a method of forming an inorganic macroporous material. In some embodiments, the method includes: providing a sample of organic polymer particles having a particle size distribution of no greater than about 10%; forming a colloidal crystal template of the sample of organic polymer particles, the colloidal crystal template including a plurality of organic polymer particles and interstitial spaces therebetween; adding an inorganic precursor composition including a noncolloidal inorganic precursor to the colloidal crystal template such that the precursor composition permeates the interstitial spaces between the organic polymer particles; converting the noncolloidal inorganic precursor to a hardened inorganic framework; and removing the colloidal crystal template from the hardened inorganic framework to form a macroporous material. Inorganic macroporous materials are also disclosed.

摘要:The present invention is to provide a method for preparing an ester condensate and a catalyst therefore; wherein the method enables synthesis of enormous amounts of ester condensates comprising a specific structure in good yield, by a reaction of carboxylic acid and alcohol in equimolar amounts, while generation of by-products is prevented; wherein the catalyst exhibits good catalytic efficiency as a catalyst for use, the use of the catalyst in small amount is sufficient, and the catalyst is reusable and can be used repeatedly; therefore, the method for preparing an ester condensate of the present invention and the catalyst therefore can be applied to industrial methods which are preferable in view of green chemistry. Esterification reaction is performed by using a catalyst comprising a zirconium(IV) compound and/or a hafnium(IV) compound and an iron compound and a gallium compound. It is preferable that the zirconium(IV) compound is a compound represented by Zr(OH) a (OR 1 ) b , wherein, R 1 represents an acyl group or an alkyl group, and each of a and b is 0 or any one of integers of 1 to 4 and the relationship of a+b=4 is satisfied, and a zirconium(IV) halide.
