The aqueous solution of hydrogen fluoride gas is a clear, colorless, fuming corrosive liquid with a strong pungent odor, easily soluble in water and ethanol, and slightly soluble in ether. Hydrofluoric acid is a weak acid with strong corrosiveness, which can strongly corrode metal, glass and silicon-containing objects. It is generally produced in laboratories with fluorite (mainly composed of calcium fluoride) and concentrated sulfuric acid. It needs sealed in a plastic bottle. The chemical industry is used to produce organic and inorganic fluorides (such as potassium fluoride, magnesium fluoride, uranium hexafluoride, calcium fluoride helium, fluororesin, fluoroplastic, fluororubber), dye synthesis, organic synthesis catalyst, and flame-retardant agent etc. In glass processing and production, it is used for frosted bulbs and general bulb treatment, glassware polishing, glass instrument scales, glassware and mirror engraving and lettering. As a cleaning agent for pickling of metal surfaces such as stainless steel. Used in the atomic energy industry, for the production of elemental fluorine and fluorides, and also as catalysts and fluorinating agents.
Tyrosine is an important nutritionally essential amino acid that plays an important role in the metabolism, growth and development of humans and animals, and is widely used in food, feed, medicine and chemical industries. It is often used as a nutritional supplement for patients with phenylketonuria, and as a raw material for the preparation of pharmaceutical and chemical products such as polypeptide hormones, antibiotics, L-dopa, melanin, p-hydroxycinnamic acid, and p-hydroxystyrene. As more high-value-added L-tyrosine derivatives such as danshensu, resveratrol, and hydroxytyrosol are found in organisms, L-tyrosine is increasingly developing in the direction of platform compounds. Tyrosine is one of the 22 kinds of amino acids used by cells to synthesize proteins. It can be used to synthesize proteins in cells. Its codons are UAC and UAU. It is a non-essential amino acid that contains polar side groups and can be synthesized by the human body. The word "tyrosine" comes from the Greek tyros, meaning cheese. It was first discovered in the casein of cheese by the German chemist Justus von Liebig in the early 19th century. When it is used as a functional group or a side group, it is called tyrosyl. Function In addition to being a proteinogenic amino acid, tyrosine has a special role in signal transduction in proteins by means of a phenolic function, which functions as a receptor for phosphate groups transferred by protein kinases (so-called tyrosine kinase receptors). organ, while phosphorylation of hydroxyl groups alters the activity of the target protein. Tyrosine also plays an important role in photosynthesis. In chloroplasts (photosystem II), it is used as an electron donor in the reduction reaction of oxidized chlorophyll, allowing it to deprotonate the phenolic OH-group, and finally in Photosystem II is reduced by four core manganese clusters. Dietary Sources Tyrosine can be synthesized from phenylalanine in the body and can be found in many high-protein foods such as chicken, turkey, fish, milk, yogurt, cheese, cottage cheese, peanuts, almonds, pumpkin seeds, sesame, soybeans, lima beans , found in avocados and bananas.
White powder, apparent density:0.35-0.90g/ml, melting point: 622�°C, easily dissolving in water; water solution is alkaline (PH value of 1% solution is 9.7); can hydrolyze into phosphate in water, has good ability in complexing metal ions; can be used to soften water; has some surfactant properties. 1.In detergents The majority of STPP is consumed as a component of commercial detergents. It serves as a "builder," industrial jargon for a water softener. In hard water (water that contains high concentrations of Mg2+ and Ca2+), detergents are deactivated. Being a highly charged chelating agent, TPP5- binds to dictations tightly and prevents them from interfering with the sulfonate detergent. 2.Food Applications STPP is a preservative for seafood, meats, poultry, and animal feeds. It is common in food production as E number E451. In foods, STPP is used as an emulsifier and to retain moisture. Many governments regulate the quantities allowed in foods, as it can substantially increase the sale weight of seafood in particular. The United States Food and Drug Administration lists STPP as "generally recognized as safe.". 3.Other Uses Other uses (hundreds of thousands of tons/years) include "ceramics, leather tanning (as masking agent and synthetic tanning agent - SYNTAN), anticaking, setting retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation, antifreeze.
Fatty alcohol polyoxyethylene ether (AEO), also known as polyoxyethylene fatty alcohol ether. It is the fastest developing and largest dosage of nonionic surfactants. This type of surfactant is an ether formed by the condensation of polyethylene glycol (PEG) and fatty alcohol, which is represented by the following general formula: RO (CH2 H2O) NH, where n is the degree of polymerization, and there are different varieties due to different degrees of polymerization of polyethylene glycol and types of fatty alcohol.
