The invention discloses a synthesis method of 2-phenyl-2-propanol and acetophenone through catalytic oxidation of cumene, the synthesis method includes that firstly, adding the cumene and a solid catalyst into a reactor, forming a suspension through ultrasonic processing, wherein the solid catalyst...
GC-MS was applied to the determination of acetophenone and 2-phenyl-2-propanol in EVA products. The contents of acetophenone and 2-phenyl-2-propanol extracted by ultrasonic from EVA materials were more than those by the method of HS-GC/MS. The optimized condition of extracted by ultrasonic...

[24]demonstrate that hydrogenation of propiophenone on Pd/C catalyst in conventional ethanol solvent produces propylbenzene as the,nal product,while in the biphasic IO/H2O system propiophenone is almost selectively reduced to 1-phenyl-1-propanol [24]. In contrast, on Pt/C catalyst and in IO/H2O...
Electrophilicity and substituents A carbon's electrophilicity is a measure of how attractive it is to nucleophiles; the more electrophilic the carbon, the more readily it is attacked. Answer and Explanation: A carbonyl carbon i...
The spectra are all very similar and resemble the triplet absorption spectra of the ketones which have lowest triplets of 3(n,π*) nature. The rate constants of hydrogenion from 2-propanol by the triplet state of these latter ketones in benzene solutions containing 2 M 2-propanol are 6.2 ...
HCl mixture at 40 DEG C. to yield 2-nitro-4,5-dimethyl-o -aminoacetophenone hydrochloride which on acylation with phenyl-acetyl chloride and pyridine at below about 5 DEG C. yields 2-nitro-4,5-dimethyl-o -phenylacetamidoacetophenone on dilution; and in (5) m-nitro-p-chloro-o...
