Hazardous Substances Data

93-58-3(Hazardous Substances Data)

Toxicity

LD50 orally in rats: 3.43 g/kg (Smyth)

Chemical Properties

It is colorless oily liquid with strong floral and cherry aromas. It is miscible with ethyl ether, soluble in methanol, ethyl ether but insoluble in water and glycerol.

Production method

Put through the hydrogen chloride gas into the methanol solution of the benzoic acid. 
It can be produced through the reaction of benzoic acid and dimethyl sulfate at elevated temperatures. 
It can be produced from the co-heating between benzoic acid and methanol in the presence of sulfuric acid.
