dimethylamine การใช้

• Dimethylamine undergoes nitrosation under weak acid conditions to give dimethylnitrosamine.
• Dimethylcarbamoyl chloride reacts with anhydrous sodium carbonate or with excess dimethylamine to tetramethylurea.
• Dimethylcarbamoyl chloride also reacts with excess dimethylamine forming tetramethylurea.
• Mannich reaction with dimethylamine and formaldehyde was described.
• The 3 products are dimethylamine, formaldehyde, and reduced electron-transferring flavoprotein.
• Dimethylamine is commonly encountered commercially as a solution in water at concentrations up to around 40 %.
• For the salts, the dimethylamine salt is still available, while the diethanolamine salt is no longer used.
• Gramine, a useful synthetic intermediate, is produced via a Mannich reaction of indole with dimethylamine and formaldehyde.
• DMAPA is commonly produced commercially via the reaction between dimethylamine and acrylonitrile ( a Michael reaction ) to produce dimethylaminopropionitrile.
• Dimethylamine vulcanizes rubber for tires, cures leather and helps make the local anesthetic a doctor might use for minor surgery.
• :dimethylamine + H 2 O + electron-transferring flavoprotein \ rightleftharpoons methylamine + formaldehyde + reduced electron-transferring flavoprotein
• :trimethylamine + H 2 O + electron-transferring flavoprotein \ rightleftharpoons dimethylamine + formaldehyde + reduced electron-transferring flavoprotein
• The reactions with dimethylcarbamoyl chloride or phosgene are highly exothermic and the removal of the resulting dimethylamine hydrochloride requires some effort.
• Then there's dimethylamine, a " reagent " that causes an interim reaction needed to make certain products.
• Elimination of a neutral molecule of dimethylamine and loss of a proton give benzaldehyde, "'6 " '.
• Synthesis took place in two steps : first a trichlorosilane was reacted with dimethylamine and the resulting monomeric aminosilane was separated from dimethylammoniumchloride.
• :PSF 3 combines with dimethylamine in solution to produce dimethylaminothiophosphoryldifluoride ( CH 3 ) 2 NPSF 2 and difluorophosphate and hexafluorophosphate ions.
• The amines shown to do this include ethylamine, isopropylamine, " tert "-butylamine, dimethylamine, and diethylamine.
• Reaction with dimethylamine affords the [ 2.2 . 2 ] propellane backbone with a dimethylamide substituent "'10 " '.
• Dimethylcarbamoyl chloride can be produced in high yields ( 90 % ) at 275 癈 by reacting phosgene with gaseous dimethylamine in a flow reactor.
