摘要:A tin catalyst for polyurethane synthesis has a structure according to the following formula (I): SnX1 n1X2 n2(L1)n3(L2)n4 whereby: each X1 and each X2 independently of each other stands for an anionic ligand, in particular a monovalent anionic ligand, especially selected from halides, hydroxides, oxygen, sulfur, alcoholates, thiolates and/or carboxylates, optionally with a saturated or unsaturated, cyclic or acyclic, branched or unbranched, substituted or unsubstituted hydrocarbon residue, whereby the hydrocarbon residues may be interrupted by heteroatoms; n1 and n2 independently of each other is 0, 1 or 2; especially the sum of n1 and n2 is 0, 1 or 2; each L1 and each L2 independently of each other stand for a polydentate chelating ligand having form 6 – 50 carbon atoms, and at least one phenoxy group forming a covalent Sn-O bond, especially 2, 3 or 4 phenoxy groups each forming a covalent Sn-O bond; at least one amine and/or imine group, in particular forming a coordination bond with Sn, especially 2 amine and/or imine group each forming a coordination bond with Sn; n3 is 1 or 2 and n4 is 0, 1 or 2; and whereby X1, X2, L1 and L2 are chemically different from each other.

摘要:Disclosed herein are a method for synthesizing one-dimensional helical mesoporous structure, in which a self-assembled structure of a glycine-derived surfactant is used as a template at room temperature to synthesize the one-dimensional helical mesoporous silica structures having a uniform pore size and a method for synthesizing a glycine-derived surfactant for synthesizing the helical nanoporous structures, in which relatively expensive surfactant can be easily recovered using an organic solvent and reused, which provides economical and environment friendly effects and the glycine-derived surfactant is synthesized by homogeneously heating a reaction product of glycine and phthalic anhydride by dielectric heating with irradiation of microwave, whereby it is possible to realize high yield of the glycine-derived surfactant, shortened synthesis time and increase in energy efficiency, leading to improvement in productivity and reduction in production cost.
