Embodiment 1
[0089] Pre-humidify the spherical macroporous silica gel until the silica gel is slightly translucent. Among them, the index of the above-mentioned spherical macroporous silica gel is spherical, the particle size is 300um~850um, and the specific surface area is 300m 2 / g~350m 2 / g, aperture The pore volume is 0.8mL / g~1.2mL / g, and the bulk density is 0.4g / mL~0.45g / mL. Humidification is done by electromagnetically atomized water vapor. Put the humidified silica gel into a three-necked flask, and add 1.2mol / L hydrochloric acid twice the mass of silica gel. Start stirring, control the stirring speed to 30r / min, heat in an oil bath, raise the temperature to 90°C, condense and reflux, absorb tail gas, react for 3h, naturally cool down to below 40°C after the reaction, filter, and collect the mother liquor for recycling. Then, the silica gel was washed with deionized water until it was neutral, and dried, and the silica gel was transferred to a drying oven at 80° C. and dried to ...
Embodiment 2
[0091] Pre-humidify the spherical macroporous silica gel until the silica gel is slightly translucent. Among them, the index of the above-mentioned spherical macroporous silica gel is spherical, the particle size is 180um~300um, and the specific surface area is 350m 2 / g~450m 2 / g, aperture The pore volume is 1.2mL / g~1.5mL / g, and the bulk density is 0.45g / mL~0.5g / mL. Humidification can be done with steam. Put the humidified silica gel into a three-necked flask, and add 2 mol / L sulfuric acid which is 6 times the mass of silica gel. Start stirring, control the stirring speed to 120r / min, heat in an oil bath, raise the temperature to 120°C, condense and reflux, absorb tail gas, and react for 8h. After the reaction, naturally cool down to below 40°C, filter, and collect the mother liquor for recycling. Then, the silica gel was washed with deionized water until it was neutral, and dried, and the silica gel was transferred to a drying oven at 140° C. and dried to a constant wei...
Embodiment 3
[0093] Pre-humidify the spherical macroporous silica gel until the silica gel is slightly translucent. Among them, the index of the above-mentioned spherical macroporous silica gel is spherical, with a particle size of 120um~180um and a specific surface area of 450m 2 / g~500m 2 / g, aperture The pore volume is 1.5mL / g~2mL / g, and the bulk density is 0.5g / mL~0.6g / mL. Humidification Humidification through water mist. Add the humidified silica gel into a three-necked flask, and add 1.4 mol / L benzenesulfonic acid that is three times the mass of silica gel. Start stirring, control the stirring speed to 60r / min, heat in an oil bath, raise the temperature to 100°C, condense and reflux, absorb tail gas, react for 5h, naturally cool down to below 40°C after the reaction, filter, and collect the mother liquor for recycling. Then, the silica gel was washed with deionized water until it was neutral, and dried, and the silica gel was transferred to a drying oven at 110° C. to dry to co...
