Embodiment 1
[0029] (1) 30g of styrene-acrylic acid copolymer (weight-average molecular weight Mw=11300, molecular weight distribution MWD=1.31, glass temperature of 125°C, melting point of 215°C) was added to 300ml of tetrahydrofuran (THF) and stirred to make styrene-acrylic acid The copolymer is completely dissolved to obtain a polymer solution;
[0030] (2) Add 30g of HgCl adsorbed by activated carbon 2 Catalyst (wherein Hg weight percent content is 13.1%, SEM picture is as figure 1 ) into the polymer solution, mixed uniformly to form a slurry-like catalyst;
[0031] (3) Evaporate 4000ml of normal hexane at 66°C, and completely pass it into the slurry-like catalyst prepared in step (2) of the stirring state in the form of gas phase normal hexane (the addition rate of normal hexane is 1ml / min), and then stop Stir, precipitate the solid matter, extract the suspended liquid, and wash the precipitated solid matter with n-hexane for 3 times to obtain an environment-friendly mercuric chlori...
Embodiment 2
[0034] (1) Add 3g of styrene-acrylic acid copolymer (weight average molecular weight Mw=11300, molecular weight distribution MWD=1.31, glass temperature is 125°C, melting point is 215°C) into 300ml tetrahydrofuran (THF) and stir to make styrene-acrylic acid The copolymer is completely dissolved to obtain a polymer solution;
[0035] (2) Add 30g of HgCl adsorbed by activated carbon 2 Catalyst (wherein Hg weight percent content is 13.1%) in polymer solution, mixes and forms slurry-like catalyst;
[0036] (3) Evaporate 4000ml of normal hexane at 66°C, and completely pass it into the slurry-like catalyst prepared in step (2) of the stirring state in the form of gas phase normal hexane (the addition rate of normal hexane is 1ml / min), and then stop Stir, precipitate the solid matter, extract the suspended liquid, and wash the precipitated solid matter with n-hexane for 3 times to obtain an environment-friendly mercuric chloride metal catalyst, totaling 32.7 g.

Embodiment 3
[0039] (1) Add 300g of styrene-acrylic acid copolymer (weight-average molecular weight Mw=11300, molecular weight distribution MWD=1.31, glass temperature of 125°C, melting point of 215°C) into 500ml of tetrahydrofuran (THF) and stir to make styrene-acrylic acid The copolymer is completely dissolved to obtain a polymer solution;
[0040] (2) Add 30g of HgCl adsorbed by activated carbon 2 Catalyst (wherein Hg weight percent content is 13.1%) in polymer solution, mixes and forms slurry-like catalyst;
[0041] (3) Evaporate 4000ml of normal hexane at 66°C, and completely pass it into the slurry-like catalyst prepared in step (2) of the stirring state in the form of gas phase normal hexane (the addition rate of normal hexane is 1ml / min), and then stop Stir, precipitate the solid matter, draw out the suspended liquid, and wash the precipitated solid matter with n-hexane for 3 times to obtain an environment-friendly mercuric chloride metal catalyst, totaling 328.5 g.
