Abstract
The invention discloses a kind of anhydrous succinic acid di-isooctyl sulfonate sodiums, it is that esterification is carried out at 120 DEG C -180 DEG C by cis-butenedioic anhydride and isooctanol, it adds sulfonated reagent and carries out sulfonating reaction at 80 DEG C -130 DEG C, dehydrating agent dehydration is added, required anhydrous solvent is added and further adjusts active quantities and produce anhydrous succinic acid di-isooctyl sulfonate sodium.Compared to water-containing products, anhydrous succinic acid di-isooctyl sulfonate sodium solution product is more suitable for the application in pesticidal preparations missible oil and the outstanding product of oil.
Description
Technical field
The present invention relates to technical field of fine, more particularly to a kind of anhydrous succinic acid di-isooctyl sulfonate sodium and
Preparation method.
Background technique
In chemical industry, fast penetrant T (fast T) refers to sulfosuccinic acid di-isooctyl sodium or succinic acid di-isooctyl
Sodium sulfonate, be it is a kind of with it is excellent infiltration, wettability anionic surfactant, be widely used in weaving, printing and dyeing,
The fields such as coating, daily use chemicals, papermaking, medicine, pesticide.The synthesis changeability of this kind of surfactant molecule structure is strong, thus it is possible to vary
The structure and number of its lipophilic group, to change its surface-active and other activity.Its synthesis is usually divided to two, and a part is amber
The synthesis of amber acid di-isooctyl, another part are the sulfonation of Aerosol OT.The amber of most domestic at present
Sour di-isooctyl sulfonate sodium is synthesized by process above, and the water content of product is big later, in pesticidal preparations missible oil and oil
It cannot effectively be applied in outstanding product, and anhydrous succinic acid di-isooctyl sodium sulfonate has filled up domestic blank.
At present about the report of anhydrous succinic acid di-isooctyl sulfonate sodium almost without, therefore develop anhydrous succinic acid two
Different dioctyl sodium sulfosuccinate salt has critically important practical value.
Summary of the invention
The object of the present invention is to provide a kind of anhydrous succinic acid di-isooctyl sulfonate sodiums.
Another object of the present invention is to provide preparation methods.
The present invention is achieved by the following technical solutions:
A kind of anhydrous succinic acid di-isooctyl sulfonate sodium, by weight percentage, including following components: sulfonation it is suitable
The sulfonated products of acid anhydride %-% and isooctanol %-% esterification, for water content less than 1%, active quantities are greater than 68%.
The preparation method of above-mentioned anhydrous succinic acid di-isooctyl sulfonate sodium, comprising the following steps: according to the proportion, cis-butenedioic anhydride
Carry out esterification at 120 DEG C -180 DEG C with isooctanol, remove unreacted isooctanol, add sulfonated reagent 80 DEG C -
Sulfonating reaction is carried out at 130 DEG C, is added dehydrating agent dehydration, is cooled down after dehydration, that anhydrous succinic acid two is obtained by filtration is different pungent
Ester sulfonate sodium.
The manufacturing method of anhydrous succinic acid di-isooctyl sulfonate sodium is maleic anhydride and isooctanol in catalyst
Under effect, certain temperature synthesis diisooctyl maleate is risen to, diisooctyl maleate exists with sodium hydrogensulfite again
Synthesizing anhydrous succinic acid di-isooctyl sulfonate sodium at a temperature of certain, adds dehydrating agent, moisture is taken in vacuum distillation out of, then
The required active quantities of solvent adjustment are added to get anhydrous succinic acid di-isooctyl sulfonate sodium is arrived.
The catalyst of esterification is selected from least one of sulfuric acid or p-methyl benzenesulfonic acid.
Preferably, the temperature range of esterification is 140 DEG C -160 DEG C.
Preferably, the temperature range of sulfonating reaction is 100-110 DEG C.
Preferably, the sulfonated reagent is selected from sodium hydrogensulfite.
The dehydrating agent is selected from least one of petroleum ether, hexamethylene, methyl oleate, toluene, ethylene glycol.
After obtaining anhydrous succinic acid di-isooctyl sulfonate sodium, adds required anhydrous solvent and further adjust activity and contain
Amount produces anhydrous succinic acid di-isooctyl sulfonate sodium product.
The anhydrous solvent be selected from ethylene glycol, propylene glycol, solvent naphtha 150#, solvent naphtha 200#, methyl oleate, ethyl alcohol,
At least one of methanol, agriculture breast 601, fatty alcohol polyoxyethylene ether.
Anhydrous succinic acid di-isooctyl sulfonate sodium solution product water content is prepared less than 1%.
The reaction equation of Aerosol OT salt is as follows:
Compared with prior art, the present invention having the advantages that
Aerosol OT salt of the invention be it is anhydrous, compared to aqueous product, anhydrous succinic acid two
Different dioctyl sodium sulfosuccinate product salt is more suitable for the application in pesticidal preparations missible oil and the outstanding product of oil.The present invention also provides anhydrous ambers
The preparation method of amber acid di-isooctyl sulfonate sodium, the preparation method technique thinking is succinct, easy to operate.
Specific embodiment
Embodiment to further illustrate the technical scheme of the present invention is used below, and still, the present invention is not by following embodiment
Limitation.
The raw materials used in the present invention source such as the following table 1:
Isooctanol, cis-butenedioic anhydride, catalyst are added in a kettle, then heats to certain temperature reaction, reaction a period of time
Afterwards, unreacted isooctanol is removed under vacuum, obtains DOM (diisooctyl maleate).DOM is added in a kettle to add again
Enter aqueous solution of sodium bisulfite, then heats to certain temperature sulfonating reaction, border ring heating side water outlet, reaction a period of time
Afterwards, dehydrating agent is added, continues to be dehydrated under vacuum, anhydrous succinic acid di-isooctyl sulfonate sodium is obtained by filtration in cooling.
