Wat is TEMPO?<\/strong><\/h2>\n

2,2,6,6-Tetramethylpiperidineoxide, afgekort TEMPO, is een piperidinenitroxideradicaal. TEMPO is oranjerood, sublimeert gemakkelijk in kristal of vloeistof en is goed oplosbaar in oplosmiddelen zoals water, ethanol en benzeen.<\/h4>\n

Het vangt vrije radicalen en onderdrukt singlet zuurstof en is een zeer effectieve oxidatiekatalysator die primaire alcoholen kan oxideren tot aldehyden en secundaire alcoholen tot ketonen.<\/h4>\n

Door het sterische hinderingseffect van de vier methylgroepen is TEMPO relatief stabiel tegen licht en warmte en is het een zeer effectieve oxidatiekatalysator die primaire en secundaire alcoholen kan oxideren tot de benodigde carbonylverbindingen. Het heeft de kenmerken van hoge opbrengst, goede selectiviteit, goede stabiliteit en recycleerbaarheid.<\/h4>\n

 <\/p>\n

2,2,6,6-Tetramethylpiperidinooxy \/ TEMPO Gebruik<\/strong><\/h2>\n

1. De katalytische oxidatie van cellulose met TEMPO wordt beschouwd als een effectieve methode. Het kan de lignocellulosevezelstructuur in het reactiesysteem in suspensie volledig oxideren en een goede basisconditie cre\u00ebren voor de daaropvolgende mechanische dissociatie.<\/h4>\n

2. TEMPO is een in water oplosbaar stabiel nitroxylradicaal. Het kan worden gebruikt om selectief de oxidatie van de primaire hydroxylgroepen van polysacchariden te katalyseren om ze om te zetten in carboxylgroepen.<\/h4>\n

3. Contact met reactie-oxidant, gebruikt voor iodobenzeendiacetyloxidatie nerol om nerol te produceren. Kortom, koper\/TEMPO wordt gebruikt voor de contactreactie van alcohol met 1 positie naar aldehyde.<\/h4>\n
