Abstract

The invention relates to a preparation method of a beta-diketone tine (IV) compound, in particular to a method for preparing the beta-diketone tine (IV) compound by using a tin (II) compound. The method is used for preparing the beta-diketone tine (IV) compound by adopting the reaction of the tin (II) compound and beta-diketone. The beta-diketone tine (IV) compound prepared in the method has the advantages of easy obtainment of raw materials, low cost, simple operation of the preparation method, reclamation of mother liquid, no environmental pollution, high yield and purity of the production and suitability for industrial production.

Description

Technical field: [0001] The invention relates to a method for producing a β-diketone tin (IV) compound, in particular to a method for producing a β-diketone tin (IV) compound from a tin (II) compound. Background technique: [0002] Metal β-diketone compounds have special properties and uses due to their structural peculiarities. Compounds of rare earths and β-diketones are widely used in new luminescent materials, NMR shift reagents, extraction chemistry, and catalytic chemistry. Chromium acetone and cobalt acetone can be used as catalysts for selective oxidation. Copper acetylacetonate and iron acetylacetonate are catalytically active for the reaction of isocyanates with alcohols to prepare carbamates. Nickel acetylacetonate is an excellent catalyst for the polymerization of styrene. Various compounds of zirconium and β-diketones can be used as catalysts for the polymerization of 1-hexene. [0003] Metal β-diketone compounds can be prepared by metal halides, hydroxides,...
