Second, the Synthetic Route we will recommend is the most important for your reference?

Epoxyphenylethane is obtained by halogenation, saponification, and distillation of styrene, sodium bromide, sulfuric acid, and liquid caustic soda.

In the lab，the synthesis below，

Add 1g of styrene, 1g of isobutyraldehyde, and 0.03g of ammonium chloride to a 150mL reaction flask, then add 50mL of acetonitrile, attach 500mL of oxygen Chemicalbook ball, stir magnetically at 60 ° C for 8h, take samples for analysis, and the reaction has been completed. The conversion rate of styrene is 100%, and the selectivity for oxidation of styrene is 82%.

Besides Safety Information is also important when handling it

Another important thing is Usage below

Used as a pharmaceutical intermediate for pharmaceutical and spice intermediates. For β- Intermediate of phenylethanol.

Phenylethanol produced by catalytic hydrogenation of styrene oxide is the main component of rose oil, clove oil and neroli oil, and is widely used in the preparation of food, tobacco, soap and cosmetics essence. It is an important synthetic spice with good aroma, low price and high consumption.
