Problems solved by technology

In order to improve the damage of laundry detergent to fabric fibers, especially silk, wool and cashmere and other animal silk and wool fabric fibers, it is necessary to control the pH value of the washing process to be weakly acidic. At this time, common anionic surfactants such as alkylbenzenesulfonic acid The washing effect of salt, fatty alcohol ether sulfate, carboxylate, etc. is poor, and it is often necessary to add nonionic surfactants. In the existing laundry detergents with oxidative bleaching and color enhancement, most of the nonionic surfactants used are fat Alcohol polyoxyethylene ether
Due to the toxicity of the biodegradation products of alkylphenol polyethers, the use of alkylphenol polyethers in civilian detergents is generally prohibited in all countries in the world, but the performance of alkylphenol polyethers is indeed the best among all nonionic surfactants. One, especially in the field of detergents, it is still difficult for people to find ideal substitutes for alkylphenol polyethers

Embodiment 1

[0012] Embodiment 1 a kind of active oxygen color-enhancing laundry detergent, its component and parts by weight thereof are:

[0013] Dodecylbenzyl alcohol polyoxyethylene ether (10) 8Kg, alkylbenzene sulfonate 10Kg, hydrogen peroxide 4Kg, coconut acid diethanolamide 1.5Kg, EDTA disodium salt 0.8Kg, chelating dispersant 0.8Kg , citric acid 1Kg, demineralized water 73.9Kg. The preparation process of dodecylbenzyl alcohol polyoxyethylene ether (10) is: get dodecylbenzene (7.38Kg), hexamethylenetetramine (4.62Kg) and 30L of trifluoroacetic acid into the reactor , the temperature rose to 120°C, reacted for 12 hours, and cooled to room temperature; after neutralization, extracted the oil layer with petroleum ether, washed the oil layer with water until neutral, evaporated the solvent to obtain 4-dodecyl-benzaldehyde, and obtained dodecane after reduction Base benzyl alcohol, and then adduct with ethylene oxide to obtain dodecyl benzyl alcohol polyoxyethylene ether (10). figure 1...

Embodiment 2

[0014] Embodiment 2 A kind of active oxygen color-enhancing laundry detergent, its components and parts by weight thereof are:

[0015] α-Methyldodecylbenzyl alcohol polyoxyethylene ether (10) 8Kg, alkylbenzene sulfonate 10Kg, hydrogen peroxide 4Kg, coconut acid diethanolamide 1.5Kg, EDTA disodium salt 0.8Kg, chelating Dispersant 0.8Kg, citric acid 1Kg, demineralized water 73.9Kg. The preparation route of α-methyldodecylbenzyl alcohol polyoxyethylene ether (10) is: commercially available dodecylbenzene and acetic anhydride are reacted to obtain dodecylphenyl methyl ketone, and then reduced to obtain α- Methyl dodecyl benzyl alcohol, after addition of ethylene oxide, α-methyl dodecyl benzyl alcohol polyoxyethylene ether (10) is obtained.

Embodiment 3

[0016] Embodiment 3 A kind of active oxygen color-enhancing laundry detergent, its components and parts by weight are:

[0017] α-Methyldodecylbenzyl alcohol polyoxyethylene ether (10) 15Kg, alkylbenzene sulfonate 15Kg, hydrogen peroxide 8Kg, coconut acid diethanolamide 5Kg, EDTA disodium salt 2Kg, chelating dispersant 2Kg, citric acid 5Kg, demineralized water 48Kg. Referring to the method stipulated in GB / T 11983-2008, the wetting power of active oxygen color-enhancing laundry detergent was measured respectively, and the results were better than those of commercially available laundry detergent.

Abstract

The invention discloses an active oxygen brightening laundry detergent, belonging to the technical field of chemical engineering. The active oxygen brightening laundry detergent disclosed by the invention comprises the following main active components: alkylbenzene alkanol polyethenoxy ether, sulfonate anionic surfactant, active oxygen agent and the like. The active oxygen brightening laundry detergent has the advantages of simple preparation steps, no environmental pollution and strong dirt-removing power, and can whiten and brighten fabrics without damage.

Description

technical field [0001] The invention relates to an active oxygen color-enhancing laundry liquid, which belongs to the technical field of chemical industry. Background technique [0002] When liquid detergent removes pigmented dirt on the surface of the fabric, it often uses oxidizing components to achieve the purpose of removing pigmented dirt by destroying the molecular structure of the pigment. The oxidizing components used can usually be divided into chlorine-containing oxidizing components and oxygen-containing oxidizing components. Typical substances mainly include: hypochlorous acid and its salts, diluted chlorine water and other chlorine-containing oxidizing components; peroxycarbonate, peroxide Oxygen-containing oxidizing components such as oxyborate, peroxysulfate, zinc peroxide, peroxyorganic acid and its salts. Liquid detergents containing chlorine oxidizing ingredients are mainly used for cleaning stains on white fabrics. The washing temperature is mostly 60°C t...
