Description
Technical field
The present invention relates to a kind of production technology of zephiran of chemical production field.
Background technology
Conventionally produced zephiran is slightly yellow liquid, and oil from amine content it is high, be single
One use carbon C12 or carbon C14 or carbon C16 or carbon C18 reactions, and this technique productions is to use carbon C12-carbon C18 according to a certain percentage
Reacted after mixing, product is water white liquid, product appearance color more preferably, improves quality of finished, mainly produces
The purposes of product is more extensive, and particularly in terms of sterilization, more thoroughly, effective time is long for sterilization.
The content of the invention
It is an object of the invention to provide a kind of oily purposes low from amine content of drop is more extensive, particularly in terms of sterilization,
Sterilization is more thorough, the production technology of the zephiran of effective time length.
The present invention is achieved by the following technical solutions：
A kind of production technology of zephiran, it is characterised in that：Production technology is comprised the following steps：
The first step：By 25.8 kilograms of ten alkyl dimethyl tertiary amide, 309.6 kilograms of Dodecyl Dimethyl Amine, myristyl two
154.8 kilograms of methyl tertiary amine, 10.32 kilograms of hexadecyldimethyl benzyl ammonium tertiary amine, 15.48 kilograms of octadecyldimethyl tertiary amine, press
According to percentage 5：60：30：2：3 ratio is sufficiently mixed, and total number reaches 516 kilograms, then in sucting reaction kettle, then
130 kilograms of the fresh water (FW) that suction is measured, then sucks 99% 140 kilograms of benzyl chloride, and suction is finished, and opens steam valve and enters
Row heating, when reaction temperature reaches 45 DEG C, steam off valve stops heating, after reaction 3-4 hours；
Second step：Suck again 137 kilograms 99% benzyl chloride in dropping tank, when reaction temperature is at 85 DEG C, open be added dropwise valve
Door carries out dropwise addition benzyl chloride and is reacted, at this moment moment attentive response temperature, and temperature is at 95 DEG C, it is necessary to which opening cooling water is carried out
There is quality accident in cooling, otherwise easy flash, dropwise reaction time control is in 3-4 hours；
3rd step：2-3 hours are incubated after completion of dropwise addition, insulation terminates sample analysis, qualified rear cooling；
4th step：It is subsequently adding 77 kilograms of industrial alcohol（Ethanol as solvent, in order to product mobility and stability more
It is good）, it is thoroughly mixed uniformly, temperature of charge is packed at 45 DEG C.
The technical indicator of product zephiran is：
Outward appearance and proterties：It is colourless to light yellow transparent liquid
Specification：≥80
PH value：6.0-9.0
Unhindered amina：≤1%.
Specific embodiment
Present disclosure is further described with reference to concrete application：
Zephiran is a kind of cationic surfactant, belongs to non oxidizing bactericide, with wide spectrum, efficiently
Sterilization algae removal ability, can efficiently control in water bacterium algae breeding and foundry loam growth, and with good sludge stripping effect and
Certain dispersion, osmosis, at the same with it is certain deoil, deodorizing capability and corrosion inhibition.Alkyldimethylbenzylammonium chlorination
Ammonium small toxicity, it is and soluble in water without accumulation property toxicity, do not affected by the water hardness, therefore it is widely used in oil, chemical industry, electricity
In the recirculating cooling water system of the industries such as power, weaving, grow to control recirculating cooling water system bacterium algae, to killing sulfate also
Opportunistic pathogen has special efficacy.Zephiran can be used as the biocide mildewcide of textile printing and dyeing industry and softening agent, antistatic
Agent, emulsifying agent, conditioner etc..
The production implementing procedure of zephiran：
The first step：By 25.8 kilograms of ten alkyl dimethyl tertiary amide, 309.6 kilograms of Dodecyl Dimethyl Amine, myristyl two
154.8 kilograms of methyl tertiary amine, 10.32 kilograms of hexadecyldimethyl benzyl ammonium tertiary amine, 15.48 kilograms of octadecyldimethyl tertiary amine, press
According to percentage 5：60：30：2：3 ratio is sufficiently mixed, and total number reaches 516 kilograms, then in sucting reaction kettle, then
130 kilograms of the fresh water (FW) that suction is measured, then sucks 99% 140 kilograms of benzyl chloride, and suction is finished, and opens steam valve and enters
Row heating, when reaction temperature reaches 45 DEG C, steam off valve stops heating, after reaction 3-4 hours, then sucks 137 kilograms
99% benzyl chloride in dropping tank, when reaction temperature is at 85 DEG C, open be added dropwise valve carry out be added dropwise benzyl chloride carry out instead
Should, at this moment moment attentive response temperature, temperature is at 95 DEG C, it is necessary to opens cooling water and is lowered the temperature, otherwise easy flash, occurs
Quality accident, dropwise reaction time control is incubated 2-3 hours in 3-4 hours, after completion of dropwise addition, and insulation terminates sample analysis, closes
Lower the temperature after lattice, be subsequently adding 77 kilograms of industrial alcohol（Ethanol as solvent, in order to the mobility and stability of product it is more preferable）,
It is thoroughly mixed uniformly, temperature of charge is packed at 45 DEG C.（Note：Proportioning per ton）.
Zephiran has 12 simultaneously, 14,16, the spy of octadecyldimethyl ammonium chloride
Property, so purposes is more extensive, especially in terms of disinfectant industry, more thoroughly, effective time is long for sterilization.
