Yield:77-58-7 97.2%

Reaction Conditions:

at 20 - 60; for 2.5 h;Temperature;

Steps:

1.1; 1.2; 1.3 Example 1 This example dibutyltin laurate synthesis method comprises the following steps:

Step 1, a solid mixture of 100 g of lauric acid and 62 g of dibutyltin oxide was stirred at 25 ° C to convert the solid mixture into a liquid mixture;Step two, the liquid mixture obtained in step one is heated to 65 ° C., and then refluxed for 2.5 h;Step three, the second step in the reflux reaction liquid mixture was cooled to 20 ° C, after standing stratified collectedThe organic phase was added with anhydrous magnesium sulfate to the organic phase to remove water for 9h and then filtered to obtain dibutyl tin dilaurate. The anhydrous magnesium sulfate was added in an amount of 8g per 100mL of organic phase Water magnesium sulfate. In this example, 153.5 g of dibutyltin dilaurate was obtained. The theoretical yield of dibutyltin dilaurate calculated according to the reaction equation was 157.9 g, and the yield of dibutyltin dilaurate was 97.2%.
