Abstract
The invention discloses a kind of high concentration lauryl sodium sulfate liquid, mainly it is prepared by the component of following parts by weight：Fatty alcohol, 245 parts；Sulphur, 41 parts；Bleaching agent, 2 parts；Complexing agent, 0.7 part；Soda bath, 170 parts；Preservative, 0.4 part；Inorganic salts, 2.1 parts, the lauryl sodium sulfate liquid prepared, concentration breaks through 30% critical point, and more competitive product is provided for conventional client, improves working substance concentration；Due to the raising of product design, the integrated costs such as transport, packaging, storage are reduced；The invention also discloses the preparation method of high concentration lauryl sodium sulfate liquid.
Description
Technical field
The present invention relates to technical field of surfactant, specifically disclose a kind of high concentration lauryl sodium sulfate liquid and
Its preparation method.
Background technology
Existing market lauryl sodium sulfate is divided into the product of three kinds of different shapes, is respectively：(active matter is more than solid
90%), (active matter is less than for lotion (activity is 70% or so, and because freezing point is too high, actual market is not applied) and fluid product
30%).On Vehicles Collected from Market, the concentration of similar fluid product is below 30% (general concentration is 28% or lower), and concentration carries again
The endless fully dissolved of product occurs in higher position, produces precipitation, opaque, opaque phenomenon occurs.
Existing production is general to have two ways, one kind to be directly diluted to low concentration product after being neutralized for sulfonation, due to such a
Method is continuous production, and the mixing time of product is short, can only produce low concentration product, endless fully dissolved and layering otherwise be present,
Even there is System Gel appearance, cause system pressure to uprush, can not normally be produced.Another kind is to be stirred with 70% lotion
Dissolving is mixed, it is such a to dissolve less than 28% strength products, the problem of same otherwise occurs.
The content of the invention
Based on this, it is necessary to which, for prior art problem, present invention aims at provide a kind of high concentration dodecyl sulphur
Sour sodium and preparation method thereof.
To realize above-mentioned technical purpose, the technical solution adopted by the present invention is as follows：
A kind of high concentration lauryl sodium sulfate liquid, is mainly prepared by the component of following parts by weight：
Fatty alcohol, 245 parts
Sulphur, 41 parts
Bleaching agent, 2 parts
Complexing agent, 0.7 part
Soda bath, 170 parts
Preservative, 0.4 part
Inorganic salts, 2.1 parts
Preferably, the bleaching agent is hydrogen peroxide.
Preferably, the complexing agent is phosphoric acid salt complexing agent.
Preferably, the preservative is benzoic acid.
Preferably, the inorganic salts are sodium chloride, sodium carbonate and sodium carbonate mixture.
A kind of preparation method of high concentration lauryl sodium sulfate liquid, the technical scheme used for：
S1, fatty alcohol and SO3 react to obtain sulfuric ester by membrane-type sulfonation；
S2, sulfuric ester obtain intermediate product LX70 by neutralization reaction system；
S3, the substantial activity thing according to LX70, dilution ratio is adjusted, active matter content is diluted to after 30%-35%, adds
Corresponding auxiliary material is added to obtain finished product afterwards.
Beneficial effects of the present invention are：1st, product design breaks through 30% critical point, provides for conventional client and more competes
The product of power, improve working substance concentration；2nd, solve in the production such as toothpaste because product design is low, the difficulty that water content can not use greatly
Topic；3rd, due to the raising of product design, the integrated costs such as transport, packaging, storage are reduced；4th, using continuous homogenizing to solve product
The problems such as dissolution velocity in production process.
Embodiment
For the feature of the present invention, technological means and the specific purposes reached, function, lower mask body can be further appreciated that
Embodiment is described in further detail to the present invention.
High concentration lauryl sodium sulfate liquid is prepared, is mainly prepared from the following materials：
Fatty alcohol, 245 parts
Sulphur, 41 parts
Bleaching agent, 2 parts
Complexing agent, 0.7 part
Soda bath, 170 parts
Preservative, 0.4 part
Inorganic salts, 2.1 parts
Concrete technology is：Fatty alcohol reacts to obtain sulfuric ester with SO3 by membrane-type sulfonation；Sulfuric ester passes through neutralization reaction system
System obtains intermediate product LX70；According to LX70 substantial activity thing, dilution ratio is adjusted, is diluted to active matter content in 30%-
After 35%, add corresponding auxiliary material and obtain finished product afterwards.
Wherein, above-mentioned technique is produced using tinuous production, and specific process parameter is：
High concentration lauryl sodium sulfate liquid prepared by the present invention is after testing, as follows compared with mill run：
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
