The present invention relates to a cleaning method of a tantalum and niobium ore conversion, the method comprising molten KOH sub tantalum and niobium ore decomposition, the decomposition product was separated diluted lye and high concentration KOH containing tantalum (niobium) Potassium solid phase by hot water leaching isolated six tantalum (niobium) and a solution containing potassium bias insoluble tantalum (niobium) potassium iron manganese slag precipitate. The hexahydrate (铌) potassium solution is crystallized by alkali to obtain potassium hexahydrate (potassium) ACID crystal and crystallization mother liquor, and the crystallization mother liquor returns to the sub-melting salt decomposition step, and the potassium bismuth (potassium) hydride and the iron-manganese slag are decomposed and precipitated by HCl. Potassium (铌) potassium crystallization. Compared with the existing high-concentration and high-toxicity HF acid (>60%) decomposition method, the method can reduce the pollution of F↑[-] from the source and increase the decomposition rate of the hardly decomposed antimony ore by more than 15%. Close to 100% of the ore decomposition rate, with good economic and environmental benefits, and can produce potassium bismuth (potassium), as an intermediate in the preparation of a series of bismuth, antimony products.
Sodium Lauryl Ether Sulfate (SLES),white or yellowish paste, an anionic Detergent and surfactant found in many personal care products (soaps, shampoos, toothpaste, etc.). SLES is an inexpensive and very effective foaming agent.SLES, sodium lauryl sulfate (SLS), ammonium lauryl sulfate (ALS), and sodium pareth sulfate are surfactants that are used in many cosmetic products for their cleaning and emulsifying properties. They behave similarly to soap. It is derived from palm kernel oil or coconut oil.
Its chemical formula is CH3(CH2)11(OCH2CH2)nOSO3Na. Sometimes the number represented by n is specified in the name, for example laureth-2 sulfate. The product is heterogeneous in the number of ethoxyl groups, where n is the mean. Laureth-3 sulfate is common in commercial products.
SLES is prepared by ethoxylation of dodecyl alcohol, which is produced industrially from palm kernel oil or coconut oil. The resulting ethoxylate is converted to a half ester of sulfuric acid, which is neutralized by conversion to the sodium salt.[1] The related surfactant sodium lauryl sulfate (also known as sodium dodecyl sulfate or SDS) is produced similarly, but without the ethoxylation step. SLS and ammonium lauryl sulfate (ALS) are commonly used alternatives to SLES in consumer products.
SLES is a kind of anionic surfactant with excellent performance.
It has good cleaning, emulsifying, wetting, densifying and foaming performance,with good solvency, wide compatibility, strong resistance to hard water, high biodegradation, and low irritation to skin and eye.
1.SLES(Sodium Laureth Sulphate) widely used in liquid detergent.; e.g. Shampoo, dishwashing detergent, bubble bath liquid, hand washing etc.
2.If using SLES(Sodium Lauryl Ether Sulfate) to replace LABSA partially, phosphate can be saved or reduced, and general dosage of active matter may be reduced, in washing powder and detergent for heavy dirty.
3.SLES(Sodium Lauryl Ether Sulphate) can be used as lubricant, dyeing agent, cleanser, foaming agent and degreasing agent.; e.g. printing and dyeing industry, petroleum and leather industry.
