Organic synthesis.

The Uses of Methyl 4-methylbenzoate

Methyl p-toluate has been employesd as catalyst to investigate the effect of internal/external donor pair in high-yield catalysts for propylene polymerization.

What are the applications of Application

Methyl 4-methylbenzoate offers interesting and pleasant variations in the Methylbenzoate theme in Ylang-Ylang, and it introdums powerful, floral notes in soap and detergent perfumes or, thanks to its low cost, it may be used even in fragrances for masking of industrial odors.

General Description

Opaque colorless to white shiny crystalline solid. Intense unpleasant odor.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Methyl 4-methylbenzoate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.

Fire Hazard

Methyl 4-methylbenzoate is combustible.
