Definition. Deoxy sugars are sugars in which one of the hydroxyl (OH) constituents on the carbon cyclic backbone is replaced with hydrogen (H). What are the methods of sugar determination? The most commonly used methods for total sugar estimation arephenol sulfuric acid (PSA), 3-methyl-2-ben...
But the way they react to fire will differ depending on what they’re made of. Vinyl flooring is fairly resistant to ignition. But once it’s alight, its impermeability to water means it can be hard to extinguish. It will also release toxic chemicals when heated, well before the point ...
diethyl ether or other ether, etc. The halide produced by this reaction may be refined by means of re-crystallization. Additionally, a compound expressed by General Formula (I-1i) can be manufactured by causing the isolated product or unisolated product to react with a halogenating agent XH ...
If there is used as reactant, instead of propargyl bromide, chloroacetonitrile, there is obtained the compound of the formula ##STR24## EXAMPLE 5 0.1 mol of the sodium salt of α-oximino-2-thienylacetonitrile with 0.12 mol of chloroacetamide is suspended in 150 ml of acetonitrile. The su...
For example, a colorless or nearly colorless fluoran leuco-dye can react with an acidic developer. Proton transfer from the developer opens the lactone ring of the leuco-dye resulting in extension of the conjugate double bond system and color formation. These coatings are complex chemical systems...
