Description

The invention does not relate to the manufacture of synthetic detergents (CMC) and can be used in the manufacture of them in powdered, pasty and lumpy commercial form. The aim of the invention is to increase the emulsifying, anti-sorption and detergent ability of the agent. The invention is illustrated with examples of testing the compositions of the described agent, the formulations of which are listed in Table. one . The detergent is prepared using a conventional spray drying method. A reclaimed amount of water, sodium alkyl benzene sulphonate, the calculated amount of alkali is loaded into a heated reactor with a working stirrer at 60-70 s, after which higher fatty acids are gradually added with continuous stirring. At the same time, the pH level should not be Nile 9. After that, alkyl phosphates are added to the reactor, and then the remaining liquid and bulk additives. The resulting mass is stirred until homogeneous and fed to the spray dryer, after which non-ionic DAS is added to the powder. Tests were carried out in comparison with the known means and standard detergent (GOST 35644-83). The detergent and antiresorption capacity of the compositions was determined by standard methods. The detergency index was determined on artificially contaminated cotton cloth. The laundry was performed in a Launder meter type laboratory washing machine at a solution concentration of 5 g / l, bath temperature 50 and 80 ° C, water hardness 5.35 mEq / l, washing duration 20 minutes. The method of determining the antiresorption capacity is based on the determination of the preservation of whiteness of uncompressed fabric when washing in a particulate suspension in a 0.25% detergent solution. The emulsifying ability of the tested detergent solutions is characterized by the amount of oleic acid converted into a stable emulsion (g / l), 72 The data obtained are given in Table. 2. Complexing agents in sodium tripolyphosphate. Functional additives are soda ash, sodium peroxoborate, sodium liquid glass, carboxymethylcellulose, optical bleach, perfume, and sodium sulfate. In these formulations, instead of the polyoxyethylene glycol ether of synthetic primary fatty alcohols of the C j-Cjo fraction of synthanol A1DSE-12 (TU-6-14-19 / 473-83), other non-ionic surfactants were used ;; sintanol DS-10 (TU-6-14-577-77) -polyethylene glycol ethers of synthetic primary alcohols fraction of syntanol LTO (TU-6-14-19-472-83) mixture of polyethylene glycol ethers of synthetic primary alcohols of fraction C 2 14 sintamide-5 (TU 6-02-640-80) - a mixture of polyoxyethyleneglycol ethers of monoethanolamides of synthetic fatty acids fraction g - C 16 -16 In the table. Figures 3, 4, and 5 show the results obtained, which indicate that the input in the STALP does not have a significant effect on the properties of the described agent. The data show that only the joint presence of a mixture of sodium salts of mono- and dialkyl phosphates and alkyl benzene sulfonate provides an improvement in detergent performance, and the absence of any of these ingredients significantly reduces them. In addition, detergent performance is significantly dependent on the amount of ingredients. When replacing sodium alkyl benzene sulphonate with sodium alkyl sulphonate, the washing ability and other indicators are significantly reduced, as reflected in Table. 6 and 7 (as the nonionic surfactants, DS-10 sintanol was introduced in these formulations). Thus, the described agent has a higher emulsifying and antiresorbability and high detergency.
