Question
This technique’s efficacy is sometimes attributed to unknown “non-thermal” effects, but it’s probably just efficient. For 10 points each:
[10m] Name this method that achieves rapid and uniform heating of a small volume of material. Pioneering work with this method was done with consumer units now banned by the ACS Journal of Chemical Education.
ANSWER: microwave-assisted synthesis [or microwave heating; or word forms of microwaving]
[10e] Microwaves have been called the modern version of this ubiquitous heating device, which produces a narrow cone of flame.
ANSWER: Bunsen burners [prompt on burners]
[10h] The Ley lab used one of these materials incorporating emim (“E-mim”) to accelerate microwave syntheses in toluene. These materials have a huge loss tangent due to their conductivity and can be used in closed containers due to their negligible vapor pressure.
ANSWER: ionic liquids [or ILs]
