What is acrylamide solution used for?
Acrylamide is used to make polyacrylamide, which is mainly used in treating waste water discharge from water treatment plants and industrial processes.In addition, acrylamide and polyacrylamides are used in the production of dyes and organic chemicals, contact lenses, cosmetics and toiletries, permanent-press fabrics.
What is the chemical formula for acrylamide?
C3H5NOAcrylamide / Formula
How do you make dinitrotoluene?
Dinitrotoluene is produced by nitration of toluene with nitrating acid (mixture of nitric acid and sulfuric acid) in which, in a first stage, the toluene is converted to mononitrotoluene (MNT) and then the mononitrotoluene is converted in a second stage to dinitrotoluene (DNT).
What is DNT TNT?
Dinitrotoluene (DNT) is mainly an explosive intermediate, produced also by nitration and/or being the result of TNT transformation (ATSDR 1998). TNT and DNT can also be associated to ammunition residues in range training areas (Brannon and Pennington 2002).
What is FEO2 and FeCO2?
All values are expressed in mean ± standard deviation. TV, Tidal Volume; VE, Ventilation; FeO2, Fractional. content of Expired Oxygen; FeCO2, Fractional content of expired CO2; VO2, Oxygen uptake; VCO2, expired CO2; RER, respiratory exchange ratio; EqO2, equivalent O2 and VE/VCO2.
Is there another name for acrylamide?
acrylamide, also called 2-propenamide, ethylenecarboxamide, or acrylic amide, a white, odourless, crystalline substance belonging to the family of organic compounds; its molecular formula is C3H5NO.
What is the difference between acrylamide and bisacrylamide?
Acrylamide is the monomer used for the production of polyacrylamide polymer. Bisacrylamide is used to make crosslinks between these polyacrylamide polymer chains. The main difference between acrylamide and Bisacrylamide is that acrylamide has a C-N bond whereas Bisacrylamide contains an N-C-N bond.
What does acrylamide mean?
Definition of acrylamide : an amide C3H5NO that is derived from acrylic acid, that polymerizes readily, and that is used in the manufacture of synthetic textile fibers.
Can you make trinitrotoluene?
❖ TNT is a yellow, odorless solid that does not occur naturally in the environment. It is made by combining toluene with a mixture of nitric and sulfuric acids (ATSDR 1995). ❖ It is a highly explosive, single-ring nitroaromatic compound that is a crystalline solid at room temperature (CRREL 2006).
How do you convert toluene to trinitrotoluene?
First, toluene is nitrated with a mixture of sulfuric and nitric acid to produce mononitrotoluene (MNT). The MNT is separated and then renitrated to dinitrotoluene (DNT). In the final step, the DNT is nitrated to trinitrotoluene (TNT) using an anhydrous mixture of nitric acid and oleum.
Who invented nitrocellulose?
contribution by Schönbein …was the first to describe guncotton (nitrocellulose). His teaching posts included one at Epsom, Eng., before he joined the faculty at the University of Basel, Switz. (1828), where he was appointed professor of chemistry and physics in 1835.
What does FEO2 stand for?
FEO2 = fraction of oxygen in expired air = variable. To prevent the need to measure both inspired and expired volumes, and introduce the measure of carbon dioxide, the Haldane transformation is used.
What is VCO2?
Carbon Dioxide Output (VCO2): refers to the amount of carbon dioxide exhaled from the body per unit time. It is expressed in ml/min. A normal value at rest is around 200 ml/min. This value increases with progressive exercise.
What is called to Fe3O4?
Iron Oxide (fe3o4)
Is acrylamide a carbon?
Acrylamide has the chemical formula of C3H5NO, and its IUPAC (formal) name is prop-2-enamide. From the name prop-2-enamide, we can see that it is a 3-carbon structure (prop), with a double bond starting at carbon 2 (en), and the starting functional group on carbon 1 is an amide.
What is APS and TEMED?
Ammonium Persulfate (APS) and TEMED catalyze the polymerization of acrylamide solutions into gel matrices. These gels are then used to separate a variety of macromolecules by size in the presence of an electric field.
Why is TEMED added last?
While making gel solution, TEMED has to be added last since it will immediately start to react with APS, and catalyze the polymerization of acrylamide and bisacrylamide. As a consequence, the following mixing and casting steps have to be completed as quickly as possible.
What is PAM polymer?
Definition. Polyacrylamides (PAMs), are polymer-based materials used to facilitate erosion control and decrease soil sealing by binding soil particles, especially clays, to hold them on site.
Is TNT more powerful than C4?
C4 is 18% more powerful than TNT. Ammonium nitrate in its pure form is a fairly weak explosive.
What is the chemical name for rust?
Chemical names for rust include iron oxide, ferric oxide and hematite. The substance is also known by its chemical formula, Fe2O3, which represents the two elements–iron and oxygen–that compose rust. Rust is both a substance and a verb describing the process that creates the substance.
What is the main catalyst for rusting?
The main catalyst for the rusting process is water. Iron or steel structures might appear to be solid, but water molecules can penetrate the microscopic pits and cracks in any exposed metal. The hydrogen atoms present in water molecules can combine with other elements to form acids, which will eventually cause more metal to be exposed.
What is Rust made of iron oxide?
Iron oxide. Several forms of rust are distinguishable visually and by spectroscopy, and form under different circumstances.Rust consists of hydrated iron (III) oxides Fe2O3. nH2O, iron (III) oxide-hydroxide (FeO (OH), Fe (OH)3. Rusting is the common term for corrosion of iron and its alloys, such as steel.
What ions are involved in rusting process?
Furthermore, these complex processes are affected by the presence of other ions, such as Ca 2+, which serve as electrolytes which accelerate rust formation, or combine with the hydroxides and oxides of iron to precipitate a variety of Ca, Fe, O, OH species.
