(S)-Phenyloxirane(S)-Styrene oxide,(S)-Epoxystyrol - Introduction
(S)-phenyloxirane is an organic compound with the chemical formula C8H8O and a molecular weight of 120.15. It is a colorless liquid with a pungent smell. It is a stereoisomer and forms an enantiomeric relationship with (R)-( )-epoxyethylbenzene.
(S)-phenyloxirane can be used to synthesize other organic compounds, such as ketones, alcohols, aldehydes, etc. It can be used as a solvent, in the polymerization reaction and catalytic reaction play the role of catalyst.
Methods for preparing (S)-phenyloxirane mainly include photochemical methods and chemical methods. The photochemical method is prepared by irradiating S-(-)-or R-( )-cyclopropylbenzonitrile under ultraviolet light, which can be epoxidized under light. The chemical method is obtained by reacting S-(-)-or R-( )-cyclopropylbenzyl alcohol with hydrogen peroxide.
Pay attention to safety when using (S)-phenyloxirane. It has a pungent odor and can pose a health hazard by inhalation or contact with the skin. Pay attention to wear chemical protective gloves, glasses and protective clothing during operation, and ensure that the operating environment is well ventilated. During storage and handling, it should be stored separately from oxidants and strong acids to avoid contact with flammable materials. In the event of a leak, clean up with appropriate adsorbent material and dispose of waste properly.
