Description
Technical field
The present invention relates to reaction unit technical field, specifically a kind of manufacture of improved cationic surfactant
Equipment.
Background technique
The theoretical reactive chemistry equation of hexadecyltrimethylammonium chloride is as follows:
C16H33NCH32+CH3Cl→[C16H33NCH33]+Cl-
Referring to Fig. 1, existing production hexadecyltrimethylammonium chloride be by 16 tertiary amine of former material material list and pure water via
Suction pipeline 5 is put into enamel reaction still 1, after being heated up to reaction temperature, by control valve 2-1 namely chlorine of chloromethanes device 2
Valve on methane steel cylinder is opened, then opens stirring motor 3 and agitating paddle 4 is driven to rotate, and by the discharging of 1 bottom of enamel reaction still
Valve 1-1 is opened, and is started logical chloromethanes, is obtained cetyl trimethyl after reaction according to the amount dereaction of reaction equation
Ammonium chloride, reaction time are generally 8 hours.
This reaction unit in process of production, because chloromethanes is gaseous state at normal temperature, thus be easy hang during the reaction
The upper layer for floating on reaction kettle is not easy to come into full contact with Dan Shiliu tertiary amine and react, even if opening stirring motor 3, still there is part chloromethane
Alkane is unable to fully and Dan Shiliu reactive tertiary amine.
Therefore, in order to which Dan Shiliu reactive tertiary amine is complete, it is necessary to be reacted using excessive chloromethanes, but excessive chloromethane
Alkane is possible to residual in the feed, because chloromethanes itself is severe toxicity, hydrochloric acid and methanol can be hydrolyzed by meeting water, has safety to human body
Hidden danger.In this way once there is chloromethanes residual, in addition to bringing security risk to production operation personnel, cetyl trimethyl is even used
The personnel for changing ammonium product also have security concerns.For producing cetyl trimethyl chlorine using traditional process equipment shown in Fig. 1
The producer for changing ammonium, is generally excluded using the following two kinds aftertreatment technology in reaction kettle and remaining chloromethane in raw material at present
Alkane:
The first technique, referring to fig. 2, vacuum pipe need to be connected to surge tank 9, and 9 domestic demand of surge tank will prepare liquid alkaline in advance, produce
Product after reaction, are vacuumized using vacuum pump 10, then can be by if there is extra chloromethanes is then extracted into surge tank 9
With, and in become reconciled after, the waste liquid in surge tank 9 needs to handle by treatment tank again, must not be directly discharged into industrial wastewater,
And then pollute water source to be processed.
Second of technique, referring to Fig. 3, product after reaction, the discharging using liquid nitrogen, from 1 bottom of enamel reaction still
Valve leads to liquid nitrogen, and for adapter tube into surge tank 9,9 domestic demand of surge tank will prepare liquid alkaline in advance, can be via pipe above enamel reaction still 1
Road is collected into surge tank 9, is avoided foam from overflowing from enamel reaction still 1 and is come, can then be neutralized in surge tank 9, and is neutralized
Waste liquid after good is also required to handle by special treatment tank, must not be directly discharged into industrial wastewater.
Therefore, using process equipment shown in Fig. 1, not only the reaction time is long, and also needs to utilize post-processing after reaction
Technique excludes excessive chloromethanes, and therefore, the artificial and cost that is spent, also having time all much increases.
Summary of the invention
The purpose of the present invention is in order to overcome the deficiencies of the prior art, pass through simple technological transformation, it is ensured that chloromethanes
It is sufficiently reacted with Dan Shiliu tertiary amine, not only reduces the theoretical amount of chloromethanes, and the reaction time can be greatly shortened, just obtained
The higher hexadecyltrimethylammonium chloride of purity.
To achieve the above object, a kind of manufacturing equipment of improved cationic surfactant is devised, including enamel is anti-
Kettle, the expects pipe for connecting enamel reaction still bottom material mouth, the chloromethanes device connecting with the expects pipe of enamel reaction still, setting is answered to ward off
Stirring motor on porcelain reaction kettle is arranged in enamel reaction still and by the agitating paddle of stirring motor driving rotation, anti-with enamel
The surge tank for answering the top duct of kettle to connect；It is equipped with outlet valve in the expects pipe at proximal port, is set on the chloromethanes device
There is control valve, it is characterised in that:
It further include feed pipe, circulating line, Roots vaccum pump；
Inlet valve, circulation valve are successively arranged along feedstock direction on the feed pipe；
The circulating line one end connection surge tank top, the other end of the circulating line be connected to be located at into
Expect on the feed pipe between valve and circulation valve；The second control valve, Luo Cizhen are successively set on the circulating line from bottom to up
Sky pump, the first control valve；
Third control valve is additionally provided in expects pipe at connection chloromethanes device between feed pipe；
One end of the bottom connection liquid back pipe of the surge tank, the other end connection of liquid back pipe are located at circulation valve and circulation
On feed pipe between pipeline, the 4th control valve is set on the surge tank.
Check (non-return) valve is respectively adopted in the control valve, control valve, the second control valve, the 4th control valve.
The inner wall of the Roots vaccum pump is covered with polytetrafluoroethylene (PTFE).
Polytetrafluoroethylene (PTFE) or glass is respectively adopted in the circulating line, feed pipe.
