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...

Abstract

The invention relates to a bactericidal algicide and antifungal agent, and simultaneously the invention also relates to a preparation method thereof. The bactericidal algae and antifungal agent is prepared from dichlorophenol, ethylenediamine, sodium hydroxide, and water; Chlorophenol and other steps prepared. The bactericidal algae and antifungal agent of the present invention has a prominent effect of inhibiting the growth of microorganisms such as mold, fungus, bacteria and algae in organic media, and also has the advantages of low dosage, low cost, long duration of sterilization, wide application range of PH, easy to add The advantages of convenient method and safe use can be widely used in the sterilization and algae killing of industrial circulating water in chemical fertilizer, chemical fiber, petrochemical, oil refining, metallurgy and other departments; at the same time, it is also an excellent antifungal agent, which can be used in leather, fabric, pulp, Sterilization and mildew prevention of paint, wood and organic materials.

Description

technical field [0001] The invention relates to a preparation method of a bactericidal algae and antifungal agent. Background technique [0002] In the circulating cooling water system, the growth of bacteria and algae and the resulting slime growth often bring hidden dangers to safe production. Add an appropriate amount of bactericide and algicide to the water to inhibit the growth of microorganisms such as mold, fungus, bacteria and algae is the most direct and effective way to solve this problem. At present, the commonly used bactericides and algicides at home and abroad are usually divided into two types: oxidizing and non-oxidizing. Dodecyldimethylbenzyl ammonium chloride, isothiazolinones, organic amines, diquaternary ammonium salts, etc. With the continuous improvement of water treatment technology, the deficiencies of these bactericides and algaecides have gradually emerged: the duration of the drug effect is short, and it can only play a momentary impact bacterici...
