The anionic surfactant triethanolamine salt product obtained by neutralizing the anionic surfactant acid product with triethanolamine has high chroma, and influences the application of downstream customers in washing, emulsifying and other products.
Disclosure of Invention
The invention aims to solve the technical problem that the anion surfactant triethanolamine salt product obtained by neutralizing an anion surfactant acid product with triethanolamine has high chromaticity, and provides a novel production method of the anion surfactant salt product, which obviously reduces the chromaticity of the product.
In order to solve the technical problems, the technical scheme of the invention is as follows:
a process for producing an anionic surfactant salt product comprising irradiating a high chroma anionic surfactant salt product with ultraviolet-containing light to obtain a low chroma anionic surfactant salt product, wherein the anionic surfactant salt product comprises an anionic surfactant triethanolamine salt.
We have surprisingly found that when the anionic surfactant salt type product does not comprise the triethanolamine salt of an anionic surfactant, the chromaticity of the high-chroma product cannot be reduced by irradiation with ultraviolet-containing light when the anionic surfactant salt type product is the sodium salt of an anionic surfactant.
In the above technical solution, preferably, the anionic surfactant triethanolamine salt includes at least one of alkyl benzene sulfonic acid triethanolamine salt, alkyl sulfuric acid triethanolamine salt, and fatty alcohol-polyoxyethylene ether sulfuric acid triethanolamine salt.
In the technical scheme, the wavelength of the ultraviolet light is 10-400 nm as understood by the technical personnel in the field. By way of non-limiting example, the wavelength of the ultraviolet light is 20nm, 30nm, 40nm, 50nm, 60nm, 70nm, 80nm, 90nm, 100nm, 110nm, 120nm, 130nm, 140nm, 150nm, 160nm, 180nm, 200nm, 210nm, 220nm, 230nm, 240nm, 250nm, 260nm, 270nm, 280nm, 290nm, 300nm, 310nm, 320nm, 330nm, 340nm, 350nm, 360nm, 370nm, 380nm, 390nm, and the like. But more preferably 100 to 300 nm. But when the wavelength is less than 200nm, the ultraviolet ray contacts with O2When (in the air, O is contained)2) Will turn O2Conversion to O3And O is3Is unfavorable to the environment, and is most preferably 200 to 300 nm. The sunlight contains ultraviolet light, and is a cheap light source containing the ultraviolet light, the applicant finds that the sunlight can also be used for the invention, but the sunlight is greatly influenced by seasons, time periods and weather, and the sunlight is stably used for actual production, so that a lot of inconvenience exists, an artificial ultraviolet light source is preferred, and the wavelength and the power of the artificial ultraviolet light source are convenient to select, and the artificial ultraviolet light source is very suitable for conventional industrial application.
In the above technical solution, preferably, the high-chroma anionic surfactant salt type product includes a solvent. The main purpose of including the solvent is to increase the fluidity of the anionic surfactant salt type product, which is beneficial to the uniform and efficient ultraviolet irradiation process.
In the above technical solution, preferably, the solvent includes water. The term "water" includes the case where a solvent other than water is usually used, the term "water" also includes the case where water is mainly used, and the term "water" also includes the case where the solvent is water.
In the above technical solution, when the high chroma anionic surfactant salt type product includes a solvent, in order to achieve the above purpose of including the solvent, a person skilled in the art can reasonably select the amount of including the solvent without creative efforts. Merely by way of example, the high chroma anionic surfactant salt type product has a solvent content of 40 to 90% by weight, such as but not limited to 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, etc., preferably 50 to 80%, more preferably 60 to 70%.
In the above technical solutions, we have found that the process of irradiating the high-chroma anionic surfactant salt product with ultraviolet-containing light to obtain the low-chroma anionic surfactant salt product relates to a photochemical reaction mechanism, and the irradiation temperature is not particularly limited, so that comparable technical effects can be obtained. By way of non-limiting example only, the irradiation temperature is 5 to 70 ℃, such as but not limited to 5 ℃, 10 ℃, 15 ℃, 20 ℃, 25 ℃, 30 ℃, 35 ℃, 40 ℃, 45 ℃, 50 ℃, 55 ℃, 60 ℃, 65 ℃ and the like, but from the viewpoint of mass production, the irradiated material is convenient for mass transfer, and the stirring irradiation is more uniform and efficient, preferably 55 to 65 ℃.
In the above technical solution, preferably, the high-chroma anionic surfactant salt type product is obtained by neutralizing an anionic surfactant acid type product with an alkali, wherein the alkali comprises triethanolamine.
In the above technical solutions, as a non-limiting example, a person skilled in the art knows that when the triethanolamine salt of an anionic surfactant is the triethanolamine salt of alkylbenzene sulfonic acid, the corresponding anionic surfactant acid is alkylbenzene sulfonic acid, and/or when the triethanolamine salt of an anionic surfactant is the triethanolamine salt of alkylsulfate, the corresponding anionic surfactant acid is alkylsulfuric acid, and/or when the triethanolamine salt of an anionic surfactant is the triethanolamine salt of fatty alcohol polyoxyethylene ether sulfate, the corresponding anionic surfactant acid is fatty alcohol polyoxyethylene ether sulfuric acid.
In the invention, the method for measuring the chromaticity comprises the following steps: the anionic surfactant salt type product was formulated with water as a 5% solids by weight solution and measured according to the standard (GB/T3413-82, liquid chemical product color determination method (Hazen units platinum-Brilliant color number)).
The chroma reduction rate is calculated according to the following formula:
the chroma reduction ratio is ((chroma before irradiation-chroma after irradiation)/chroma before irradiation) × 100%.
The higher the chroma reduction rate, the better the effect of reducing chroma.
The present invention will be described in detail below with reference to specific embodiments.
