In this article, we will get acquainted with the use of phosphoric acid in soap and non-soap cleaners.Orthophosphoric acid (H3PO4), also commonly called phosphoric acid, is a crystalline solid. The melting point is 42.35 degrees Celsius or 108.2 degrees Fahrenheit. In its less concentrated form, it is a colorless syrup. Crude acid is made from phosphate rock, while acid is made with a higher purity than white phosphorus.
Soaps are usually made from glyceride oils and fats, and dark-colored soaps are needed unless there is a very high quality oil or fat in them.When soap is made from such dark dyes, the dyes are transferred into the soap and darken its color. This is undesirable, because white soap or light-colored soap is more popular with consumers. For this reason, this art has developed countless processes, the aim of which is to produce oil-based soaps from dark soaps.One of these processes involves the hydrolysis or separation of oils and glyceride fats and the distillation of fatty acids to separate them from the dye. Soap is made from fatty acids. This process does not require extensive equipment, high temperatures and pressures for splitting, large vacuums for distillation, and other non-economically viable requirements.The odor of the products and the decomposition caused by the high temperatures used are often transmitted to the soap.A common method is to bleach oil or grease with soil bleach, especially an active bleach soil. The use of such soil imposes a severe bleaching effect, but the amount of bleach that can be done with a reasonable amount of soil is often not the desired amount, especially in cases where the soap is very dark. In general, it is not practical to use more than 5% to 6% of the soil in such a bleach due to the cost and loss of soil adsorbed reservoirs with the dye.A wide range of chemicals are suggested as bleaching agents for oils and fats, including various oxidizing agents, reducing agents, halogen compounds, acids and so on.The industry relies primarily on earth bleach this is a Applications Phosphoric acid.
Soap oil or fat with a combination of phosphoric acid and an oxygen-releasing compound, preferably of any kind, performs an initial treatment, followed by oil or fat, ordinary soil bleach, and then soap. It turns and the soap turns white with a reducing agent. Due to the dark inventory that is used as a raw material, a significant bleaching action can be performed and unexpected light-colored soaps can be produced.Apparently using a combination of an oxygen-releasing compound and a combination of phosphoric acid not only performs an unexpected bleaching action on the oil or fat, but also compares the oil or fat in a unique condition compared to the performance of these substances separately. The person leaves.The oil or fat to be bleached is stimulated by a small amount of commercial grade phosphoric acid and a small amount of hydrogen peroxide solution. When the fat mixture and these factors are stimulated, the temperature rises slightly and the mixing continues at this temperature for the desired time.Following this, ventilation and sludge are released. The liquid is then washed with hot water (1 to 10%) to remove phosphoric acid, pigments, and flocculants with unreacted hydrogen peroxide. Washing water and water-soluble materials become a lower layer and can be removed. Further rinsing with 5 to 50% warm water may be done to remove phosphoric acid and its compounds. Accurate alkaline neutralization may be performed in conjunction with water rinsing at any stage.
The washed oil may be dried according to the usual processes and then bleached with more complete soil or bleaching soil in the usual way. This involves mixing the stock with about 2 to 6 percent of the soil and stirring the mixture at high temperature.This operation and its changes in the industry are well known.The bleached material is then transferred to a soap making machine, where it is processed to make boiled soap in the usual way, that is, it is soaped with the required amount of caustic and washed to remove glycerin, then soap. According to a known technique, such as sodium hydrosulfite or sodium formaldehyde sulfoxylate is bleached with a small amount (0.01 to .5%) of a reducing agent. Soap is then produced in various forms.Phosphoric acid is commercially available and relatively inexpensive. Commercial orthophosphoric acid is available in concentrations of 70 to 85% and may be easily used. Water and impurities that make up the balance of such commercial acids are not harmful to the work process. Any other phosphoric acid compound may be used, such as pyrophosphoric acid and acidic salts of phosphoric acids such as potassium or sodium dihydrogen phosphate or disodium dihydrogen pyrophosphate, and pentavalent and organic phosphoric acid compounds.
It is a safe and steam-free product for removing lime deposits, uric acid stains, rust, greasy soap scum and other organic stains.
Concentrating solutions, based on phosphoric acid, are used in commercial washing machines, steam cleaners, boilers, or wherever lime and calcium deposits may accumulate.
It is used for concrete, granite, non-polished natural stone, grout, tile, brick, ceramic, porcelain and masonry surfaces.Cleaning casting surfaces including precast concrete, natural non-polished surfaces including flared and crushed granite, crushed and edged marble, slate, mine tiles, flaming and edged limestone, ceramic tiles without Glaze, porcelain tile, cement slurry, brick, concrete, mortar and masonry are used.So phosphoric acid can be used safely in soap and non-soap cleaners.
