STYRENE ALCOHOL - Introduction
(±)-1-Phenylethanol, also known as phenylethanol, is a volatile organic compound. Its chemical formula is C8H10O and its molecular weight is 122.16.
The following is about the properties of (±)-1-phenylethanol:
-Appearance: Colorless liquid or white crystalline solid.
-Odor: Has a fragrant odor.
-Solubility: Soluble in most organic solvents, such as ethanol and ether.
The main uses of (±)-1-phenylethanol include:
-Chemical synthesis: It is an important starting material for the synthesis of other organic compounds, such as ethers, esters, aldehydes and ketones.
-Flavor and fragrance industry: used as an additive in the manufacture of perfumes, flavors and fragrances.
The method for preparing (±)-1-phenylethanol usually includes the following steps:
1. Benzyl alcohol and dimethyl malonate are reacted under the catalysis of alkali to form dimethyl 2-benzene acetate.
2. The 2-benzene acetic acid dimethyl ester in reducing agent (such as hydrogen and catalyst) under the action of reduction to generate (±)-1-phenyl ethanol.
Regarding the safety information of (±)-1-phenylethanol, the following matters should be noted:
-Pure liquid (±)-1-phenylethanol is irritating and may cause damage to the eyes, skin and respiratory tract.
-Need to operate in a well-ventilated place and avoid inhalation of vapors or contact with skin.
-When using or storing, keep away from open fire sources to avoid fire or explosion.
