Embodiment 1
[0044]In a 500ml three-neck flask, add 200g of water and 53g of sodium hydroxide in turn, stir to dissolve, continue to stir until the temperature is below 35°C, add 104g of gallic acid, and stir for 30min until dissolved. Raise the temperature of the above reaction solution to 40°C, add 49g of carbon disulfide, control the reaction temperature at 45-50°C, and continue the reaction for 5 hours; Agent diethyl dithiocarbamate ferric, stirred for 1 hour to obtain an orange-red aqueous solution, which is a photodegradable photosensitive molecular sulfide mineral inhibitor.
Embodiment 2
[0046] In a 500ml three-neck flask, add 180g of water and 71g of sodium hydroxide in sequence, stir to dissolve, continue to stir until the temperature is below 35°C, add 78g of citric acid, and stir for 40min until dissolved. Raise the temperature of the above reaction solution to 45°C, add 35g of carbon disulfide, control the reaction temperature at 45-55°C, and continue the reaction for 4 hours; Add 3.5g of photodegradant ferric dibutyldithiocarbamate, stir for 2h, let stand for 12h, filter to remove trace precipitate at the bottom, take the supernatant to obtain an orange-red aqueous solution, which is the photodegradable photosensitive molecular sulfide inhibitor.
Embodiment 3
[0048] In a 500ml three-necked flask, add 168g of water and 122g of polyacrylamide in turn, stir to dissolve, gradually add 9.5g of NaOH, continue stirring to keep the temperature below 30°C. After fully dissolving, 20g of carbon disulfide was added dropwise, and the temperature was raised step by step. Raise the temperature to 35°C, keep it for 1h, continue to raise the temperature to 45°C, keep it for 2h, and finally raise the temperature to 65°C, and keep it for 1h. After the reaction solution is placed and cooled to below 30°C, it will be a sulfide mineral inhibitor; then add 10.5g of photodegradant ferric dibutyl dithiocarbamate to it, stir for 3 hours, let it stand for 12 hours, and filter to remove the trace precipitate at the bottom. The supernatant was taken to obtain an orange-yellow aqueous solution, which was the photodegradable photosensitive molecular sulfide inhibitor.
