Abstract: |
|||
| The present invention provides an effective preparation method of 2-ethyl stannous caproate with high stannous content. The said organic stannous salt is mainly used as catalyst of polyurethane foam plastics and silicone rubber. The stannous content which can be extracted by use of present known synthetic method is less than 28.2%. Bu use of the invented reaction condition and technological condition the 2-ethyl stannous caproate whose stannous content by 28.6-29.2%, output rate by 97-98%, stannous recovery ratio by 94-98% can be obtained. | |||
