Embodiment 1

[0030] For the bactericidal algicide and antifungal agent of the present embodiment and its preparation method, see figure 1 , the steps are:

[0031] 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;

[0032] 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

[0037] The bactericidal algicide antifungal agent of the present embodiment and preparation method thereof are:

[0038] 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;

[0039] 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;

[0040] 3) After the reflux, sto...

Embodiment 3

[0044] 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;

[0045] 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;

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

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...
