Examples
preparation example 1
[0045] The preparation method of modified organic divalent metal 1 is as follows: in a 500ml three-necked bottle, mix 50mmol of monobutyltin oxide and 200mmol of hexanoic acid, stir at 100°C for 3h and use a water separator to remove the generated water in time Separation, and then filtered while hot to obtain the modified organic divalent metal 1.
preparation example 2
[0047]The preparation method of the modified organic divalent metal 2 is as follows: in a 500ml three-necked bottle, mix 50mmol of monotetradecyl zinc oxide and 220mmol of octanoic acid, stir at 120°C for 3h and use a water separator to separate the resulting water Separated in time, and then filtered while hot to obtain the modified organic divalent metal 2.
preparation example 3
[0049] The preparation method of the modified organic divalent metal 3 is as follows: in a 500ml three-necked bottle, mix 50mmol of monooctyltin oxide and 210mol of dodecanoic acid, stir at 110°C for 3h and use a water separator to separate the resulting water Separated in time, and then filtered while hot to obtain the modified organic divalent metal 3.
