Sodium carbonate (CAS 497-19-8)

1.273,0033,00

Sodium carbonate (CAS 497-19-8)

Sodium carbonate, Na2CO3·10H2O, (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na2CO3 and its various hydrates. All forms are white, odourless, water-soluble salts that yield moderately alkaline solutions in water. Historically, it was extracted from the ashes of plants growing in sodium-rich soils. Because the ashes of these sodium-rich plants were noticeably different from ashes of wood (once used to produce potash), sodium carbonate became known as “soda ash.” It is produced in large quantities from sodium chloride and limestone by the Solvay process.

Sodium molybdate (CAS 7631-95-0)

Sodium molybdate (CAS 7631-95-0)

Sodium molybdate, Na2MoO4, is useful as a source of molybdenum. This white, crystalline salt is often found as the dihydrate, Na2MoO4·2H2O.

The molybdate(VI) anion is tetrahedral. Two sodium cations coordinate with every one anion.

It is used in industry for corrosion inhibition, as it is a non-oxidizing anodic inhibitor. The addition of sodium molybdate significantly reduces the nitrite requirement of fluids inhibited with nitrite-amine, and improves the corrosion protection of carboxylate salt fluids. In industrial water treatment applications where galvanic corrosion is a potential due to bimetallic construction, the application of sodium molybdate is preferred over sodium nitrite. Sodium molybdate has the advantage in that the dosing of lower ppm’s of molybdate allow for lower conductivity of the circulating water. Sodium molybdate at levels of 50-100 ppm offer the same levels of corrosion inhibition as sodium nitrite at levels of 800+ ppm. By utilizing lower concentrations of sodium molybdate, conductivity is kept at a minimum and thus galvanic corrosion potentials are decreased.

Solid paraffin (granulated, panels) (CAS 8002-74-2)

Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal or oil shale that consists of a mixture of hydrocarbon molecules containing between twenty and forty carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), and its boiling point is above 370 °C (698 °F). Common applications for paraffin wax include lubrication, electrical insulation, and candles; dyed paraffin wax can be made into crayons. It is distinct from kerosene and other petroleum products that are sometimes called paraffin.

Un-dyed, unscented paraffin candles are odorless and bluish-white. Paraffin wax was first created by Carl Reichenbach in Germany in 1830 and marked a major advancement in candlemaking technology, as it burned more cleanly and reliably than tallow candles and was cheaper to produce.

In chemistry, paraffin is used synonymously with alkane, indicating hydrocarbons with the general formula CnH2n+2. The name is derived from Latin parum (“barely”) + affinis, meaning “lacking affinity” or “lacking reactivity”, referring to paraffin’s unreactive nature.

Sodium phosphate tribasic dodecahydrate is also known as trisodium phospate or TSP. It is a highly soluble in water and widely used as a cleaning agent. The pH of a 1% solution is typically around 12, making this reagent sufficiently alkaline for saponification of grease and oils. In combination with surfactants, TSP is an excellent agent for cleaning everything from laundry to concrete driveways. This versatility and low manufacturing price made TSP the basis for a plethora of cleaning products sold in the mid-20th century. Trisodium phosphate is used in the isolation of mycobacteria, including culturing of tubercle bacilli. Has been used as a protein precipitant in certain applications and in co-precipitation and fractionization of nucleotides. May be used for the preservation of biologically active soil samples. Because of the alkaline pH, TSP disrupts cytoplasmic and outer membranes of Salmonella enterica cells making it useful in preventing the spread of bacteria.It is used in photographic developing, clarifying sugar, removing boiler scale, softening water and manufacturing of paper. They are added to many foods as an emulsifier to prevent oil separation. It can be utilized as a leavening agent. Some instances of these foods include the batter coating on breaded fish or chicken, and commercially baked cakes. Adding this item to food increases the shelf life of the food, maintaining the texture and visual aspect of the food.

Urea (CAS 57-13-6)

2.000,00118,30

Urea (CAS 57-13-6)

Urea, also known as carbamide, is an organic compound with chemical formula CO(NH2)2. This amide has two –NH2 groups joined by a carbonyl (C=O) functional group.

Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is a colorless, odorless solid, highly soluble in water, and practically non-toxic (LD50 is 15 g/kg for rats).[6] Dissolved in water, it is neither acidic nor alkaline. The body uses it in many processes, most notably nitrogen excretion. The liver forms it by combining two ammonia molecules (NH3) with a carbon dioxide (CO2) molecule in the urea cycle. Urea is widely used in fertilizers as a source of nitrogen (N) and is an important raw material for the chemical industry.

Friedrich Wöhler discovered that urea can be produced from inorganic starting materials, which was an important conceptual milestone in chemistry in 1828. It showed for the first time that a substance previously known only as a byproduct of life could be synthesized in the laboratory without biological starting materials, thereby contradicting the widely held doctrine of vitalism, which stated that only living things could produce the chemicals of life.

0,00

Urea Phosphate (CAS 4861-19-2)

Urea phosphate is a fertilizer having NPK formula 17-44-0. It is soluble in water, and produces a strongly acidic solution. Urea phosphate is sometimes added to blends which contain calcium nitrate, magnesium nitrate and potassium nitrate to produce water-soluble formulas such as 15-5-15 and 13-2-20. The acidity of urea phosphate allows Ca, Mg and P to co-exist in solution. Under less acidic conditions, there would be precipitation of Ca-Mg phosphates. Urea phosphate is often used in drip irrigation to clean pipe systems.

Chemically, the urea phosphate compound is made of an equimolar mix of urea and phosphoric acid crystallizing together, and freely disassociating when dissolving in water. It is available in fertilizer vendor bags that carry a UP signet on the packaging.
