Sodium polyacrylate Usage And Synthesis

Dispersant	Sodium polyacrylate is a commonly used dispersant, also known as 2-sodium acrylate homopolymer, S sodium polyacrylate. It is colorless or light yellow viscous liquid in room temperature, and non-toxic, alkaline, insoluble in organic solvents such as ethanol, acetone but easily soluble in water and aqueous sodium hydroxide. However, for aqueous solution of calcium hydroxide, magnesium hydroxide, due to the increase of alkaline metal ions, it is first dissolved and then precipitated. It can work without entrustment under alkaline conditions or being concentrated for several folds with molecular weight of about 500-3000. It can disperse the microcrystalline or sediment of calcium carbonate, calcium sulfate salts into the water without precipitation, and thus achieving the purpose of preventing entrustment. Besides used as the descaling dispersant in power plants, chemical plants, fertilizer plants, refineries and air conditioning systems, cooling water system, it is also widely used in industries like paper and textile, ceramics, paints, building materials. When used as a paper coating dispersant, it has a relative molecular mass in 2000-4000. When coating concentration is 65% to 70%, it can still have a good rheology and aging stability. The product in molecular weight from 1000 to 3000 is used as water quality stabilizer as well as scaling control agent of concentrated black liquor. Products with molecular weight higher than 100,000 is used as coatings thickener and water retention agent, which can increase the viscosity of synthetic emulsion such as carboxylated styrene-butadiene latex and acrylate emulsion latex and prevent the water from being separated out as well as maintain the stability of the coating system . Product of molecular weight of 1 million or more can be used as a flocculant. It can also be used as super absorbent polymer, soil conditioners, as well as a thickening agent and emulsion dispersant in the food industry. The molecular structure of sodium polyacrylate molecule is water soluble linear polymers. Small molecular weight molecule is as liquid with large molecule counterparts shown as solid. Solid product is shown as a white powder or granules, and is odorless, water-swellable, and soluble in aqueous caustic soda. Moreover, it is extremely hygroscopic. It is a polymer compound containing hydrophilic and hydrophobic groups. It is slowly soluble in water and form a highly viscous transparent liquid whose 0.5% solution having a viscosity of about 1000cp with the viscosity being not as swelling as CMC and sodium alginate. But owing to the ion phenomenon of many anionic groups in the molecule makes the molecular chain being longer, increasing the apparent viscosity to form highly viscous solution. It has a viscosity which is 15-20 times as high as sodium carboxymethyl cellulose (CMC) and sodium alginate. It has a high alkali resistance with viscosity changing only little and it is also non-perishable. Heat treatment, neutral salts, and organic acids have very small effects on its viscosity. However, it has increased viscosity upon alkaline condition. Intense heating to 300 degrees will not cause decomposition of it. Due to its property as a kind of electrolyte, it is vulnerable to acids and metal ions which cause the decrease of viscosity. In case of more than a sufficient amount of divalent metal ions (e.g. aluminum, lead, iron, calcium, magnesium, zinc), it will form insoluble salt which cause intermolecular crosslink and thus gelation and further precipitation. But it is still as solution upon a low amount of divalent metal ion, making it be able to be used as detergent additives which play a role in preventing soil re-deposition.
Food grade sodium polyacrylate	In abroad, it has begun to apply sodium polyacrylate for being used in a variety of food for thickening, gluten and preservation since 1960s. In 2000, the Ministry of Health of china also officially approved it as a food grade thickener. Application limitation: According to China's food additive standards. The applications of food grade sodium polyacrylate used are as follows: 1. being used as a thickener in foods has the following effects: (1) Enhance the adhesion ability to raw flour protein. (2) Make starch particle to combine with each other and dispersion penetrate into the mesh structure of the protein. (3) Form dough with a dense texture and being smooth in its glossy surface. (4) It forms a stable dough colloid for preventing soluble starch exudation. (5) It has a strong water-holding capacity which can make moisture be uniformly maintained in dough and prevent drying. (6) It can be used to improve the dough extensibility. (7) Make the raw material in the oil component be stably dispersed into the dough. 2. it is used as the electrolyte for protein interactions, change the protein structure, and enhance food viscoelasticity and improve the organization. 3. Application examples: (1) Bread, cakes, noodles, macaroni, improve utilization of raw materials, improve the taste and flavor with the amount of 0.05%. (2) Fish paste-like products, canned food, dried seaweed, etc., to strengthen its organization, to keep fresh flavor, enhanced sense of smell. (3) Sauce, tomato sauce, mayonnaise, jam, cream, soy sauce, thickeners and stabilizers. (4) Fruit juice, wine, etc., dispersants. (5) Ice cream, Kara honey Seoul sugar, improve taste and the stability. (6) Frozen food, aquatic products, surface jellies (preservation). 4. Owing to its slow dissolution rate in water; it can be pre-mixed with sugar, powdered starch syrup, emulsifier, etc., to improve the dissolution rate. 5. Sodium polyacrylate can be used as sugar, salt, beverage clarifying agent (polymer coagulant). The above information is edited by the Chemicalbook of Dai Xiongfeng.
