The technical name for acetal plastic is polyoxymethylene, or POM for short. It may also be known by the brands Acetron® or Delrin®. This thermoplastic is a semi-crystalline engineering material that offers a large continuous-use temperature range. More specifically, it is able to hold on...
One negative characteristic specific to Delrin over other acetal plastics is its increased centerline porosity—an inconsistency in the center of the plastic caused by gas escape in the cooling process. While not a concern when the center of a rod is to be drilled out, this property can be pr...
It is especially effective for solubilizing a wide range of polymers, including those that are not soluble in the most common organic solvents, such as: polyamides, polyacrylonitriles, polyacetals, polyesters (e.g. polyglycolide), and polyketones. It has also found use in biochemistry to ...
A catalyst is used in a chemical reaction to speeds the rate at which the reaction occurs. Therefore, biological catalysts are enzymes. Enzymes...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
However, as the water temperature increases, its solubility will gradually decrease. In the pH range of 3 to 11, the fatty alcohol Polyethylene Glycol Monocetyl Ether is hydrolytically stable. However, they also slowly oxidize in the air, producing some oxidation products, such as acetaldehyde an...
Which of the following reagents can be used to reduce acetaldehyde to ethyl alcohol? Name all the alcohols that have the formula C5H12O. How many ethers have the formula C5H12O? What reagents can be used to reduce an aldehyde into an alcohol? What is the IUPAC ...
Methylglyoxal is a highly reactive alpha-oxoaldehyde formed endogenously in numerous enzymatic and nonenzymatic reactions.
When someone refers to a “vape” or “vaping,” they're describing the act of vaporization, which consists of inhaling and exhaling aerosols, commonly called vapor, produced from an e-cigarette or vaporizer device. Vaping is popular among consumers because it offers a smokeless way to enjoy ...
Acetal An acetal is a functional group with the connectivity R2C(OR')2). Here, the R groups can be organic fragments (a carbon atom, with arbitrary other atoms attached to that) or hydrogen, while the R' groups must be organic fragments not hydrogen. Hemiacetal A hemiacetal or a hemiket...
Most acetic acid produced by the chemical industry is used to prepare acetates. Acetates, in turn, are primarily used to make polymers. Nearly half of acetic acid production goes to preparing vinyl acetate, whic
