Description
Technical field
The present invention relates to chemical field, specifically a kind of preparation method of nonionic surfactant.
Background technique
With economic rapid development, society constantly improves, the quality of life that people are continuously improved, and surfactant is wide
The wetting agent being used as in aqueous preparation generally.For example, it is a variety of that alkylphenol ethoxylate (APE), which is widely acknowledged to be,
The excellent surface activating agent of application.However, APE surfactant has the public of its Environmental compatibility to perceive poor problem.Separately
Outside, it is limited by the increasingly tighter environment rule for being intended to reduce its consumption in many applications (including emulsion polymerization (EP))
Chapter.Therefore, the use decline of APE classes of surfactant, and supplier seeks to provide the other surfactants for substituting it.
The preparation method for being badly in need of the surfactant of simple and quick save the cost improves, and meets industrial production demand.Energy after improvement
It improves our quality of life while promoting the development of relevant industries, there is very big economic benefit.As it can be seen that being carried out to textile
It antibiotic finish and improves its performance and has very important meaning.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of non-ionic surfaces in order to solve the deficiencies in the prior art
The preparation method of activating agent.
Technical solution of the present invention is as follows:
A kind of preparation method of nonionic surfactant, uses following steps: polyurethanes or different Buddhist is happy
Ketone diisocyanate is added to reactor, and epoxychloropropane is added under agitation, adds after being heated to 50 DEG C after mixing evenly
Enter catalyst, persistently stirred under keeping warm mode 1-3 hours, adjusts pH value to neutrality, vacuum distillation dehydration simultaneously filters, then Xiang Fanying
Excessive sodium hydroxide is added inside device, is warming up to 80 DEG C again and is stirred to react 3-5 hours, room temperature decentralization is set after stopping heating
It 10-20 hours, is filtered after acid solution stirring is added.
The catalyst is boron trifluoride etherate, or is tin tetrafluoride, and additive amount is total by mass percentage
The 2% of amount.
The molal weight ratio of the polyurethanes or isophorone diisocyanate and epoxychloropropane is 10: 1-4.
Compared with existing nonionic surfactant, present invention has the main advantage that
The present invention solves the deficiency in prior synthesizing method, solves the problems, such as that energy consumption is excessive, has saved cost；This
Outside, the advantages that this method also has catalyst usage amount few, and reaction process is simple, and the operation is more convenient, therefore be very suitable for
Industrial production.Oil field clean fracturing fluid is prepared using obtained Gemini surface active agent as thickening agent, there is heatproof endurance of cutting
Can be good, solid-carrying performance is good, it is not necessary that gel breaker is added, without anti-the advantages that arranging.
Specific embodiment
The present invention is described in detail below by embodiment.
Embodiment 1
A kind of preparation method of nonionic surfactant, uses following steps: polyurethanes is added to instead
Device is answered, epoxychloropropane is added under agitation, catalyst is added after being heated to 50 DEG C after mixing evenly, is held under keeping warm mode
Continuous stirring 2.5 hours adjusts pH value to neutrality, and vacuum distillation dehydration simultaneously filters, then excessive hydrogen-oxygen is added to reactor the inside
Change sodium, be warming up to 80 DEG C again and be stirred to react 5 hours, room temperature decentralization is set 15 hours after stopping heating, and mistake after acid solution stirring is added
Filter.Catalyst is boron trifluoride etherate, or is tin tetrafluoride, and additive amount is total amount by mass percentage
2%.
The molal weight of polyurethanes and epoxychloropropane ratio is 10: 3.
Embodiment 2
Isophorone diisocyanate is added to reactor, stirred by a kind of preparation method of nonionic surfactant
Epoxychloropropane is added under the conditions of mixing, catalyst is added after being heated to 50 DEG C after mixing evenly, persistently stirs 1.5 under keeping warm mode
Hour, pH value is adjusted to neutrality, and vacuum distillation dehydration simultaneously filters, then to the excessive sodium hydroxide of addition inside reactor, again
It is warming up to 80 DEG C to be stirred to react 3.5 hours, room temperature decentralization is set 18 hours after stopping heating, is filtered after acid solution stirring is added.
Wherein, catalyst is boron trifluoride etherate, or is tin tetrafluoride, and additive amount is total by mass percentage
The 2% of amount.
Wherein, the molal weight of isophorone diisocyanate and epoxychloropropane ratio is 10: 2.5.
The above is only a specific embodiment of the invention, but scope of protection of the present invention is not limited thereto, any to be familiar with
Those skilled in the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all cover
Within protection scope of the present invention.Therefore, protection scope of the present invention should be subject to the protection scope in claims.
