Exempel på hur man kan använda DIOLS i en mening

• A further scholarship allowed him to study Chemistry at the University of Manchester, where he pursued his interest in industrial chemistry and was awarded a BSc followed by a PhD in 1956 for research into the stereochemistry of diols.
• For academic research and pharmaceutical areas, vicinal diols are often produced from the oxidation of alkenes, usually with dilute acidic potassium permanganate or Osmium tetroxide.
• Polyols containing two, three and four hydroxyl groups are diols, triols, and tetrols, respectively.
• Most notably periodic acid will cleave vicinal diols into two aldehyde or ketone fragments (Malaprade reaction).
• Sodium periodate can be used in solution to open saccharide rings between vicinal diols leaving two aldehyde groups.
• More efficient fluorination of aliphatic halides can be achieved with a combination of crown ether and bulky diols in acetonitrile solvent.
• Isosorbide is a bicyclic chemical compound from the group of diols and the oxygen-containing heterocycles, containing two fused furan rings.
• The reaction of periodic acid oxidizes the vicinal diols in these sugars, usually breaking up the bond between two adjacent carbons not involved in the glycosidic linkage or ring closure in the ring of the monosaccharide units that are parts of the long polysaccharides, and creating a pair of aldehydes at the two free tips of each broken monosaccharide ring.
• IBX is notable for oxidizing vicinal diols (or glycols) to diketones without cleavage of the carbon-carbon bond, but oxidative cleavage of glycols to two aldehydes or ketones can occur when modified conditions are used (elevated temperatures or trifluoroacetic acid solvent).
• Although the method can produce diols, overoxidation to the dicarbonyl compound has led to difficulties isolating the vicinal diol.
• In the Fétizon oxidation, silver carbonate on celite acts as an oxidising agent to form lactones from diols.
• To prepare polymers by step-growth polymerization, telechelic polymers like polymeric diols and epoxy prepolymers can be used.
• Polycarbonates produced by phosgenation of these two diols produces a polymer with improved thermal stability.
• The Upjohn dihydroxylation is still often used for the formation of cis-vicinal diols; however, it can be slow and is prone to ketone byproduct formation.
• This conversion is widely applicable for amines and alcohols, as well as aminoalcohols, diols, and diamines.
• Like other diols, this viscous colourless liquid is used as plasticizer and also forms polyesters that are used as emulsifying agents and resin intermediates.
• Hepoxilin-epoxide hydrolase converts the epoxide residue in hepoxilins A3 and B3 to Vicinal (chemistry) diols as exemplified in the following enzyme reaction for the metabolism of hepoxilin A3 to trioxilin A3:.
• A copolyester is a copolymer synthesized by modification of polyesters, which are combinations of diacids and diols.
• TPU is a block copolymer consisting of alternating sequences of hard and soft segments or domains formed by the reaction of (1) diisocyanates with short-chain diols (so-called chain extenders) and (2) diisocyanates with long-chain diols.
• In organic synthesis, among its many applications, it is particularly useful in directing regioselective O-alkylation, acylation, and sulfonation reactions for diols and polyol.
