Embodiment 1
[0025] For the bactericidal algicide and antifungal agent of the present embodiment and its preparation method, see figure 1 , the steps are:
[0026] 1) Feeding: Put 417kg of molten p-chlorophenol, 41.7kg of formaldehyde, 1.9kg of molecular sieve, and 130g of zinc chloride into the condensation kettle in sequence. When pumping p-chlorophenol and formaldehyde, the vacuum degree should be controlled at 0.05MPa, and open the If the cooling water of the distillation condenser is pumped into the p-chlorophenol receiving tank, it should be released immediately and re-pumped into the condensation kettle;
[0027] 2) Heating and reflux: After the feeding is completed, close the cooling water of the distillation condenser, close the valve on the distillation column, open the reflux cooling water and the vent valve, and start stirring. After 15 minutes, turn on the heater to heat up. When the temperature rises to reflux, Control the temperature at 110°C to maintain reflux for 4 hours;...
Embodiment 2
[0032] The bactericidal algicide antifungal agent of the present embodiment and preparation method thereof are:
[0033] 1) Feeding: Put 360kg of molten p-chlorophenol, 40kg of formaldehyde, 1.2kg of molecular sieve, and 120g of zinc chloride into the condensation kettle in sequence. When pumping p-chlorophenol and formaldehyde, the vacuum should be controlled at 0.05MPa, and the distillation Condenser cooling water, if any raw material is pumped into the p-chlorophenol receiving tank, it should be released immediately and pumped into the condensation kettle again;
[0034] 2) Heating and reflux: After the feeding is completed, close the cooling water of the distillation condenser, close the valve on the distillation column, open the reflux cooling water and the vent valve, and start stirring. After 15 minutes, turn on the heater to heat up. When the temperature rises to reflux, Control the temperature at 114°C to maintain reflux for 4 hours;
[0035] 3) After the reflux, sto...
Embodiment 3
[0039] 1) Feeding: Put 440kg of molten p-chlorophenol, 40kg of formaldehyde, 2.4kg of molecular sieve, and 120g of zinc chloride into the condensation kettle in sequence. When pumping p-chlorophenol and formaldehyde, the vacuum degree should be controlled at 0.05MPa, and the distillation Condenser cooling water, if any raw material is pumped into the p-chlorophenol receiving tank, it should be released immediately and pumped into the condensation kettle again;
[0040] 2) Heating and reflux: After the feeding is completed, close the cooling water of the distillation condenser, close the valve on the distillation column, open the reflux cooling water and the vent valve, and start stirring. After 15 minutes, turn on the heater to heat up. When the temperature rises to reflux, Control the temperature at 112°C to maintain reflux for 4 hours;
[0041]3) After the reflux, stop heating, open the valve on the distillation column, close the reflux vent valve, turn on the distillation c...
