Quinoline-3-carboxylic Acid
Quinoline-3-carboxylic acid is an aryl carboxylic acid. Aryl carboxylic acids are an important class of fine chemicals, which can be obtained by oxidizing methyl groups with 3-methyl-quinoline.
Resorcinol
Resorcinol has bactericidal, fungicidal and anti-itching effect with the bactericidal effect being 1/3 of the phenol and also a low irritating and corrosive property. At low concentration, it can play the role promoting the regeneration of horny while having keratin exfoliation effect at high concentration. It is mainly used for rubber adhesives, plastics, synthetic resins, synthetic fibers, dyes, preservatives, anti-itch, anti-fungal agent, analytical reagent and can also be used to treat ringworm, eczema, seborrheic dermatitis, acne and psoriasis.
SODIUM METASILICATE PENTAHYDRATE
Sodium metasilicate pentahydrate, commonly known as instant water glass, is an inorganic salt product. It is a silicon fine chemical product developed by European and American countries in the 1960s. Ronald Planck company of France, Daxiang company of America and Eka company of Sweden all have tens of thousands of tons of production capacity. It is a non-toxic, tasteless and pollution-free white powder or crystal particle, which is easy to dissolve in water, insoluble in alcohol and acid, has water absorption, and the aqueous solution is alkaline. It is easy to absorb moisture and deliquesce when placed in the air. It has the ability of descaling, emulsifying, dispersing, wetting, permeability and buffering for pH value. It has strong decontamination, strong pH buffering ability, neutralizing acid dirt, emulsifying fat and oil, and inorganic matter It has the function of anti flocculation and anti-corrosion to metals.
SOLVENT BLACK 5
Nigrosine is an important raw material for chemical synthesis in dye industry. For a long time, the cotton printing and dyeing factory directly dyed with aniline, and oxidized the cotton fiber to obtain the original color cloth with strong black light and excellent quality. Aniline black is also used in cotton printing, whether it is direct printing cloth or anti-dyeing printing cloth, aniline is lower in cost than dyes, and the color is black, washable and lightfast. It was one of the main production processes in the 1950s.
Salicylic Acid
Guanidine isothiocyanate is a kind of uncoupler and a kind of strong denaturant of protein. It can dissolve protein and make the secondary structure of protein disappear. The cell structure is degraded and nucleoprotein is separated from nucleic acid rapidly. It is used to denature and lyse cells, extract RNA and DNA, without RNase and DNase activity.
Sodium Acetate Trihydrate
Sodium acetate is also known as sodium acetate. Colourless, tasteless, transparent monoclinic, columnar crystal, or white crystalline powder. No smell. A little bitter. It is easily weathered and combustible in the air. Dehydration to anhydrous substance at 123 ℃. Soluble in water, slightly soluble in ethanol.
Sodium Carbonate
The chemical formula of sodium carbonate is Na2CO3, commonly known as soda ash, soda, alkali ash and washing alkali, which is white powder and strong electrolyte in general. With a density of 2.532g/cm3 and a melting point of 851 ° C, it is easy to dissolve in water and has the general properties of salt. It is a weak acid salt, slightly soluble in anhydrous ethanol and insoluble in propanol. After dissolving in water, it will undergo hydrolysis reaction, making the solution alkaline and corrosive to a certain extent. It can neutralize with acid, generate corresponding salt and emit carbon dioxide. It can decompose at high temperature to produce sodium oxide and carbon dioxide. Long term exposure to the air can absorb water and carbon dioxide in the air, generate sodium bicarbonate, and form a hard block. Hygroscopicity is very strong, it is easy to form hard block, and it does not decompose at high temperature.
Sodium Dithionite
Sodium hydrosulfite, also known as sodium hydrosulfite, is a white sand like crystal or light yellow powder chemical product, with melting point of 300 ℃ (decomposition), ignition temperature of 250 ℃, insoluble in ethanol, soluble in sodium hydroxide solution, which reacts strongly with water and burns.
Sodium Dodecylbenzenesulphonate
Sodium dodecylbenzene sulfonate, SDBS for short, white or light yellow powder or flake solid. It is difficult to volatilize, soluble in water and becomes translucent solution. It is stable in chemical properties and slightly toxic to alkali, dilute acid and hard water. It is a common anionic surfactant.
Sodium Fluoride
Sodium fluoride is a colorless and bright crystal or white powder compound with specific gravity of 2.25, melting point of 993 ℃ and boiling point of 1695 ℃. Soluble in water (solubility 10 ° C 3.66, 20 ° C 4.06, 30 ° C 4.22, 40 ° C 4.4, 60 ° C 4.68, 80 ° C 4.89, 100 ° c5.08), hydrofluoric acid, slightly soluble in alcohol. The aqueous solution is weak alkaline and soluble in hydrofluoric acid to form sodium hydrofluoride, which can corrode glass. Toxic! It is widely used as phosphating accelerator, agricultural insecticide, sealing material, preservative and other fields in coating industry.
Sodium Formate
It is also called sodium formic acid. There are two crystal water in the crystal, so it is also called sodium formate dihydrate, sodium formate dihydrate and sodium formic acid dihydrate. Sodium formate is one of the simplest organic carboxylates. It is a white crystal or powder with a slight smell of formic acid. Slightly deliquescent and hygroscopic. Soluble in about 1.3 parts of water and glycerin, slightly soluble in ethanol, octanol, insoluble in ether. Its aqueous solution is alkaline. When heated, sodium formate decomposes into hydrogen and sodium oxalate, and then generates sodium carbonate. Sodium formate is mainly used in the production of insurance powder, oxalic acid and formic acid. In leather industry, it is used as camouflage acid in chrome tanning process, catalyst and stabilizer, reducing agent in printing and dyeing industry. Sodium formate is harmless to human body and has irritating effect on eyes, respiratory system and skin.
Sodium Gluconate
Sodium gluconate is widely used in industry. It can be used as high-efficiency chelating agent, steel surface cleaning agent, glass bottle cleaning agent, aluminum oxide coloring in electroplating industry, high-efficiency retarder, high-efficiency water reducer, etc. in construction, textile printing and dyeing, metal surface treatment, water treatment and other industries.
