Methyl benzoate Usage And Synthesis

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.
Category	Toxic substances.
Toxicity grading	Poisoning
Acute toxicity	Oral-rat-LD50: 1177 mg/kg; Oral-Mouse LD50: 3330 mg/kg.
Skin irritation data	Rabbit 10 mg/24 hr Mild; Eyes-rabbit 500 mg/24 hr mild.
Explosive and hazardous characteristics	High-temperature, explosive.
Chemical Properties	Methyl benzoate is a colorless, oily, transparent, liquid. Pleasant odor.
Chemical Properties	colourless to light yellow fragrant liquid
Chemical Properties	Methyl paraben is methyl ester of p-hydroxybenzoic acid. It does not occur naturally and is produced commercially by esterification of p-hydroxybenzoic acid. Methyl benzoate has a fruity odor, also similar to cananga.
Chemical Properties	Methyl benzoate has a fruity odor, similar to cananga.
Uses	In perfumes (Peau d'Espagne).
Uses	Methyl benzoate is used in perfumes..
Preparation	By heating benzoic acid and dimethyl sulfate to high temperature, or by exchange between ethyl benzoate and methanol in KOH solution.
Production Methods	The compound is manufactured by heating methanol and benzoic acid in the presence of sulfuric acid or by passing dry hydrogen chloride through a solution of benzoic acid in methanol . It may also be produced by the alcoholysis of benzonitrile . It is a by-product of ozonolysis of water .
Hazard	Toxic by ingestion.
Health Hazard	Irritating to the eyes, nose, throat, upper respiratory tract, and skin. May cause allegic skin and respiratory reactions.
