Embodiment 1

[0031] A kind of diisooctanoic acid tin oxide complex is prepared according to the following method:

[0032] Add solvent and tin source compound into the reaction kettle, react with excess isooctanoic acid at 180°C, react for 2 hours, remove excess isooctanoic acid under reduced pressure, lower the temperature below 100°C, add 15% sodium hydroxide solution, and stir React for 0.5h, let it stand for 15min to separate layers, separate the lower layer of alkaline water and solid product; then collect the alkaline water and solid product in a stirred tank and let it settle for 2 hours, after the solid settles at the bottom of the tank, take out the alkaline solution, and add ethanol to the solid Stir evenly, filter, add butyl acetate to the filter cake, stir evenly, filter with a tin-containing adsorption fiber membrane, and dry the filter cake to obtain a tin oxide complex of diisooctanoate.

[0033] The described tin-containing adsorption fiber membrane is prepared according to...

Embodiment 2

[0040] A kind of diisooctanoic acid tin oxide complex is prepared according to the following method:

[0041]Add solvent and tin source compound into the reaction kettle, react with excess isooctanoic acid at 250°C, react for 10 hours, remove excess isooctanoic acid under reduced pressure, lower the temperature below 100°C, add 40% sodium hydroxide solution, and stir React for 2 hours, let it stand for 45 minutes to separate layers, and separate the lower layer of alkaline water and solid product; then collect the alkaline water and solid product in a stirred tank and let it settle for 5 hours. Uniformly, filter, add butyl acetate to the filter cake and stir evenly, use a tin-containing adsorption fiber membrane to filter, and dry the filter cake to obtain diisooctanoic acid tin oxide complex.

[0042] The described tin-containing adsorption fiber membrane is prepared according to the following method: 400Kg of ethyl acetate, 100Kg of polymethyl methacrylate, 0.5Kg of dimethyl...

Embodiment 3

[0049] A kind of diisooctanoic acid tin oxide complex is prepared according to the following method:

[0050] Add solvent and tin source compound into the reaction kettle, react with excess isooctanoic acid at 225°C, react for 5 hours, remove excess isooctanoic acid under reduced pressure, lower the temperature below 100°C, add 25% sodium hydroxide solution, and stir React for 1 hour, let it stand for 30 minutes to separate the layers, and separate the lower layer of alkaline water and solid product; then collect the alkaline water and solid product in a stirred tank and let it settle for 4 hours.

Abstract

The invention relates to the field of fine chemical engineering, in particular to a preparation method of a diisocaprylic acid tin oxide complex. The preparation method of the diisooctanoic acid tin oxide complex is simple and has industrial prospects; the prepared diisooctanoic acid tin oxide complex has catalytic esterification capacity and can be used as a heterogeneous catalyst, and various catalytic esterification indexes of the diisooctanoic acid tin oxide complex are equivalent to those of stannous octoate. The product as an esterification reaction catalyst can be separated from the product through filtration after the reaction is finished, no wastewater is generated, and the separated catalyst can be repeatedly used, so that the pollution is avoided, and the economy is improved.

Description

technical field [0001] The invention relates to the field of fine chemical industry, in particular to a preparation method of a diisooctanoic acid tin oxide complex. Background technique [0002] Catalysts for ester reactions include homogeneous catalysts and heterogeneous catalysts. Among them, homogeneous catalysts have higher activity, but the separation of catalysts and products is more troublesome. Some reactions use water washing or alkali washing to separate catalysts from products, such as using sulfuric acid Or the reaction of p-toluenesulfonic acid as an esterification catalyst. [0003] 201080030981.4 discloses partially homopolymerizing a hydroxylated fatty acid compound, reacting the partially homopolymerized hydroxylated fatty acid compound with an alcohol to form an intermediate product, and capping the intermediate product with an acid, anhydride or ester to prepare a secondary hydroxy fatty acid Esters of oligomers. The ester of secondary hydroxy fatty aci...
