Example Embodiment

[0029] Example one

[0030] The bactericidal, algae, and antifungal agent of this embodiment and its preparation method are referred to figure 1 , The steps are:

[0031] 1) Feeding: Put the melted p-chlorophenol 417kg, formaldehyde 41.7kg, molecular sieve 1.9kg, and zinc chloride 130g into the condensation kettle one by one. When pumping p-chlorophenol and formaldehyde, the vacuum degree should be controlled at 0.05MPa and opened The cooling water of the distillation condenser, if any raw material is pumped into the p-chlorophenol receiving tank, it should be discharged immediately and pumped into the condensation kettle again;

[0032] 2) Heating and reflux: After feeding, turn off the cooling water of the distillation condenser, close the valve on the distillation column, open the reflux cooling water and the vent valve, start stirring, 15 minutes later, turn on the heater to increase the temperature, and when the reflux occurs, Control the temperature at 110°C and maintain the...

Example Embodiment

[0036] Example two

[0037] The bactericidal, algae, and antifungal agent of this embodiment and its preparation method are as follows:

[0038] 1) Feeding: Put the melted p-chlorophenol 360kg, formaldehyde 40kg, molecular sieve 1.2kg, and zinc chloride 120g into the condensation kettle one by one. When pumping p-chlorophenol and formaldehyde, the vacuum degree should be controlled at 0.05MPa, and the distillation is turned on Condenser cooling water, if any raw material is pumped into the p-chlorophenol receiving tank, it should be discharged immediately and pumped into the condensation kettle again;

[0039] 2) Heating and reflux: After feeding, turn off the cooling water of the distillation condenser, close the valve on the distillation column, open the reflux cooling water and the vent valve, start stirring, 15 minutes later, turn on the heater to increase the temperature, and when the reflux occurs, Control the temperature at 114℃ to maintain reflux for 4 hours

[0040] 3) Af...

Example Embodiment

[0043] Example three

[0044] 1) Feeding: Put the melted p-chlorophenol 440kg, formaldehyde 40kg, molecular sieve 2.4kg, and zinc chloride 120g into the condensation kettle one by one. When pumping p-chlorophenol and formaldehyde, the vacuum degree should be controlled at 0.05MPa, and the distillation is turned on Condenser cooling water, if any raw material is pumped into the p-chlorophenol receiving tank, it should be discharged immediately and pumped into the condensation kettle again;

[0045] 2) Heating and reflux: After feeding, turn off the cooling water of the distillation condenser, close the valve on the distillation column, open the reflux cooling water and the vent valve, start stirring, 15 minutes later, turn on the heater to increase the temperature, and when the reflux occurs, Control the temperature at 112℃ to maintain reflux for 4 hours;

[0046] 3) After the reflux is over, stop heating, open the valve on the distillation column, close the reflux vent valve, open...

Abstract

The invention relates to a sterilization, algae removal and anti-fungus agent, and its preparing method. It is made of dichlorophen, ethanediamine, caustic soda and water.Wherein, the dichlorophen is made by precommising and heating the chlorophenol, methyl aldehyde, molecular screen and catalyser zinc chloride, as well as backflowing and steaming the p-chlorophenol. The invention has the projecting function of suppressing the microorganism such as mould, fungus, bacteria and algae growing in the organic medium, and the advantages of small dosage, economic cost, long sterilization duration, large pH applicability, convenient processing method and safe usage. It can be used in industry cycle sterilization in water of the departments as fertilizer, chemical fiber, petrochemical plant, oil refining and metallurgy. It is also a merit anti-fungus agent, can be used to sterilize in leather, textile, paper pulp, coating material, wood and organic material.

Description

technical field [0001] The invention relates to a bactericidal algicide and antifungal agent, and simultaneously the invention also relates to a preparation method thereof. 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 i...
