The present invention has high fluidity and a high concentration of α-
The present invention relates to an aqueous slurry containing a sulfo fatty acid ester salt. α-Sulfo fatty acid ester salts obtained by neutralizing α-sulfo fatty acid esters have good hard water resistance, excellent detergency, and are mild to the skin, making them useful for cleaning. It is useful as a surfactant. Unlike higher alcohols, α-olefins, etc., fatty acid esters have a slow sulfonation reaction rate, so sulfonation must be carried out under harsh reaction conditions in order to obtain a predetermined sulfonation reaction rate. The resulting sulfonated product, i.e. α-
Sulfo fatty acid esters are extremely colored and it is not possible to obtain light colored products. Therefore, various bleaching methods have been proposed. According to the method of bleaching in the presence of a lower alcohol, as proposed in Japanese Patent Publication No. 53-46825, the color tone of α-sulfo fatty acid ester can be significantly improved. became possible. However, the product obtained by the above method contains lower alcohols and has a strange odor, so it is difficult to use it as an activator after bleaching.
- It was necessary to remove the lower alcohol from the sulfo fatty acid ester salt to a desired amount or less and to deodorize it. Possible methods for topping and deodorizing lower alcohols from α-sulfo fatty acid ester salts include evaporation, flash distillation, and spray drying. However, the spray drying method has a problem in that it is difficult to recover the removed lower alcohol. On the other hand, in the evaporation method, flash distillation method, etc., it is not easy to remove alcohol sufficiently, and even if the alcohol is removed, the problem is that the viscosity is high and handling is difficult. The viscosity of α-sulfo fatty acid ester salt aqueous solution is
The concentration of the salt increases rapidly from about 20 to 30% by weight or more, and if the concentration becomes even higher, a gel may be formed and fluidity may even be completely lost. As this solution is further concentrated, the viscosity begins to decrease slightly when the concentration of the salt reaches approximately 50% by weight, reaching a state with some fluidity of 300 to 400 poise at around 60% by weight, but after that, the viscosity begins to decrease slightly. The viscosity begins to increase and eventually transforms into a solid α-sulfo fatty acid ester salt. In general, it is desirable that the AI concentration (active ingredient concentration) of a surfactant solution be as high as possible from an economic standpoint, such as manufacturing equipment, transportation, and packaging materials.Furthermore, from the standpoint of handling, it is desirable to have a solution with a lower viscosity. requested. For these reasons, it is advantageous to use it in the form of a highly concentrated slurry, similar to surfactants such as alkylbenzene sulfonates. However, in general, when a highly concentrated slurry containing 50% by weight or more of a surfactant is made, the viscosity increases and handling becomes difficult. Various techniques have been proposed to reduce the viscosity of highly concentrated slurries such as sulfates. For example, a method of adding an inorganic salt of a halogen such as sodium chloride (USP 3954679), a method of adding polyethylene glycol (Japanese Patent Publication No. 50-116383), a method of adding excess alkali and alkylene oxide (Japanese Patent Publication No. 1983-116383),
-16504) etc. However, even if these conventional techniques are used, α-sulfo fatty acid ester salts exhibit significantly different behavior regarding viscosity, and the viscosity of high-concentration slurry cannot be effectively lowered. The present invention was developed as a result of intensive studies on a series of steps such as bleaching of α-sulfo fatty acid ester in the presence of a lower alcohol, subsequent neutralization, and removal of the lower alcohol. This was achieved by discovering that by adjusting the amount of ate within a certain range, a slurry with low viscosity and easy handling could be obtained. That is, the α-sulfo fatty acid ester salt-containing slurry of the present invention has α-sulfo fatty acid ester salts represented by the general formula ().
-One or more sulfo fatty acid ester salts
It is characterized by containing 40 to 60% by weight and 3 to 8% by weight of one or more types of lower alcohol sulfates having 1 to 4 carbon atoms. FIG. 1 shows triangular coordinates showing the composition range of the highly concentrated aqueous slurry of the present invention, and a slurry with high concentration and low viscosity can be obtained within the shaded area in the figure. By lowering the viscosity in this way, lower alcohols can be easily removed, especially when using the method of bleaching in the presence of lower alcohols as proposed in Japanese Patent Publication No. 53-46825.
It will be very advantageous. Furthermore, the effects of the present invention are not limited to the production of α-sulfo fatty acid ester salts through a series of steps such as bleaching α-sulfo fatty acid esters in the presence of lower alcohols, subsequent neutralization, and removal of the lower alcohols. do not have. That is, even in the α-sulfo fatty acid ester salt-containing slurry produced in a system in which lower alcohol does not exist, 40 to 65% by weight of the α-sulfo fatty acid ester salt and 3 to 65% of the lower alcohol sulfate (which may be added later) are used.
By containing 8% by weight, a product with high concentration and low viscosity can be obtained, which is very effective from the viewpoint of economical considerations such as transportation and packaging materials, as well as from the viewpoint of handling properties. The α-sulfo fatty acid ester salt of the present invention has the general formula
(In the formula, R represents a straight chain or branched alkyl group having 8 to 22 carbon atoms, R' represents a straight chain or branched alkyl group having 1 to 4 carbon atoms, M is sodium,
Indicates an alkali metal such as potassium. ), and preferably R has 12 to 18 carbon atoms.
R' has 1 to 3 carbon atoms. Specific examples of lower alcohol sulfates include methanol, ethanol, isopropyl alcohol, and butanol, sodium sulfate ester salt, and potassium sulfate ester salt. Since the slurry containing a high concentration of α-sulfo fatty acid ester salt of the present invention is used as an activator, the lower alcohol content is preferably 1% or less.
Further, the content of the inorganic salt is preferably 10% or less based on the α-sulfo fatty acid ester salt. The aqueous slurry of the present invention is produced by sulfonating a fatty acid ester represented by the general formula () R-CH 2 -COOR' () (in the formula, R and R' are the same as in the general formula), and converting the obtained sulfonated product into a lower Obtained by bleaching in the presence of alcohol and then removing lower alcohols. Examples of sulfonation include membrane sulfonation method,
This can be carried out by a tank-type sulfonation method, etc.
Anhydrous SO 3 or SO 2 is used as the sulfonating agent.
SO 3 gas converted with a V 2 O 5 catalyst and diluted with nitrogen and dry air can be used. The appropriate molar ratio of SO 3 used is 1.0 to 1.7, and the reaction temperature is 50 to 1.7.
100℃ is appropriate. After the reaction is completed, the temperature is 80° to 100°.
Preferably, it is aged for 10-20 minutes at °C. The sulfonated product (α-sulfo fatty acid ester) thus obtained is significantly colored and is bleached using a bleaching agent such as hydrogen peroxide in the presence of a lower alcohol. Bleaching is carried out by controlling the amount of lower alcohol sulfate produced as a by-product to be 5 to 15% by weight based on the α-sulfo fatty acid ester salt. For example, after adding a lower alcohol to the obtained α-sulfo fatty acid ester, hydrogen peroxide is added, and the mixture is heated at 50 to 100°C.
This is done by bleaching for ~120 minutes. The amount of alcohol added is α-sulfo fatty acid ester 100
The appropriate amount of hydrogen peroxide is 5 to 20 parts by weight, and the appropriate amount of hydrogen peroxide to be added is 0.5 to 10 parts by weight. The bleached product is then neutralized to obtain an α-sulfo fatty acid ester salt. Neutralization can be done, for example, by using 5 to 50 wt% of sodium hydroxide or potassium hydroxide.
It is carried out using an aqueous solution, containing 30 to 55% by weight of α-sulfo fatty acid ester salt (α-SF), and containing α-SF
A neutralized product containing 5 to 15% by weight of lower alcohol sulfate is obtained. As already explained, the obtained neutralized product contains a relatively large amount of lower alcohol and also has an odor. Therefore, it is necessary to dealcoholize the neutralized product, but according to the research of the present inventors, α-sulfo fatty acid esters bleached in the presence of lower alcohols can be neutralized to produce α-sulfo fatty acid esters. Contains 30 to 55% by weight of salt (α-SF), and contains α-SF
A neutralized product composition containing 5 to 15% by weight of lower alcohol sulfate relative to α-SF and 8 to 40% by weight of lower alcohol relative to α-SF, and the lower alcohol is removed by evaporation from this neutralized product. As a result, it satisfies the composition range shown in Figure 1 and has a low viscosity.
Moreover, it is a light-colored α-SF with a low content of lower alcohol (typically 1% by weight or less) and excellent odor.
A highly concentrated aqueous slurry is obtained. Here, the content of the lower alcohol may be adjusted in advance by controlling the amount added during bleaching, or may be adjusted by adding the lower alcohol after bleaching, for example, after neutralization, so that it falls within the above range. By adjusting the composition of the neutralized product to the above composition range and performing the dealcoholization treatment, lower alcohols can be efficiently removed and deodorized using commonly used evaporators because the product does not pass through a high viscosity region when lower alcohols are removed. . Therefore, a high-quality α-sulfo fatty acid ester salt with very little lower alcohol content, good odor, and light color without deterioration of color tone can be obtained. A general evaporator can be used to remove the lower alcohol, and for example, a forced stirring type film evaporator is preferable. Operating conditions are supply temperature 50~150℃, pressure 5~760mmHg, ABS, preferably 20~500mm.
Hgabs, heating temperature below 180℃, residence time within 20 minutes. By removing the lower alcohol, an aqueous slurry having the composition range shown in FIG. 1 is obtained, and this slurry has a low viscosity of 200 poise or less and is therefore easy to handle. Note that the removal is preferably performed such that the lower alcohol content of the aqueous slurry is 1% by weight or less. Example: 2900 parts by weight of extremely hardened beef tallow fatty acid methyl (average molecular weight 290) was placed in a tank reactor equipped with a gas inlet pipe, thermometer and stirrer and heated to 80°C. Diluted to 5vol% with gas
After introducing 1200 parts by weight of SO 3 (molar ratio to ester: 1.5) over 60 minutes, the mixture was further aged at 80° C. for 20 minutes to obtain a sulfonated product. 500 parts by weight of this sulfonated product was placed in a container equipped with a stirrer, 61.0 parts by weight of methanol and 22.0 parts by weight of 35% hydrogen peroxide were added, and the mixture was stirred at a temperature of 80°C for 60 minutes to obtain a bleached product. Next, 64.5 parts by weight of 18.6% NaOH aqueous solution was placed in a container and heated to 40°C, and the above bleached product was added to this.
100 parts by weight was added and stirred vigorously to obtain an acidic neutralized product with a pH of 3.5. Next, a 5% NaOH aqueous solution was gradually added over 30 minutes to prepare a neutralized product with a pH of 6.5, and a neutralized product A was obtained. Next, this neutralized product is passed through a heat exchanger to 100℃.
After heating the mixture to 160 kg/m 2 ·Hr, it was passed through a Leuwa film evaporator (heating temperature 180°C, vacuum degree 200 mmHg) and topped with methanol to obtain a topped product A. B to J were prepared in the same manner and are shown in Table 1 along with A. Regarding C, the amount supplied to the evaporator is 60 kg/
