Embodiment 1
[0033] At a temperature of 40°C, 47.5g of phenol, 300mL of water and 4.45g of water-soluble catalyst were added into the reaction flask and stirred evenly, and then 51mL of 30% hydrogen peroxide was quickly added dropwise to make a raw material solution. When the temperature of the microchannel reactor rose to 90° C., the raw material solution was continuously input into the microchannel reactor at a flow rate of 50 mL / min for hydroxylation reaction. The measurement results are shown in Table 2.
Embodiment 2
[0035] At a temperature of 40°C, 48.7g of phenol, 300mL of water and 4.45g of water-soluble catalyst were added into the reaction flask and stirred evenly, and then 71mL of 30% hydrogen peroxide was quickly added dropwise to make a raw material solution. When the temperature of the microchannel reactor rose to 100° C., the raw material solution was continuously input into the microchannel reactor at a flow rate of 60 mL / min for hydroxylation reaction. The measurement results are shown in Table 2.
Embodiment 3
[0037] At a temperature of 40°C, 47.8g of phenol, 300mL of water and 4.45g of water-soluble catalyst were added into the reaction flask and stirred evenly, and then 91mL of 30% hydrogen peroxide was quickly added dropwise to make a raw material solution. When the temperature of the microchannel reactor rose to 110° C., the raw material solution was continuously input into the microchannel reactor at a flow rate of 70 mL / min for hydroxylation reaction. The measurement results are shown in Table 2.
