methanolysis การใช้

• Acid-catalysed methanolysis is necessary to achieve near-quantitative yields of the desired methyl esters, RCO 2 Me.
• Both, the alcoholysis of propiolactone with methanol as well as the methanolysis of acrylonitrile via intermediately formed acrylamide sulfate are also proven but obsolete processes.
• A commercial FAME extraction protocol developed for identification of bacteria, a mild alkaline methanolysis protocol and PLFA-extraction / derivatization were compared for effectiveness.
• Methanolysis is only rarely carried out in industry today because polyester production based on dimethyl terephthalate has shrunk tremendously, and many dimethyl terephthalate producers have disappeared.
• When used as a reagent in organic synthesis to convert carboxylic acids to their methyl esters, trimethylsilyldiazomethane undergoes acid-catalysed methanolysis, forming diazomethane " in situ ".
• The reaction of 2-methylglutarimide with e . g . methanol ( methanolysis ) produces the diester dimethyl-2-methylglutarate in the presence of titanium dioxide or lanthanum oxide.
• The mechanism involves silylation of the carbonyl oxygen and elimination of " tert "-butyl iodide ( ), methanolysis of the silyl ester to the carbamic acid ( ) and finally decarboxylation to the amine ( ).
