It is an isomer of xylene. Other isomers include o-xylene and m-xylene. p-Xylene is used on a large scale for the manufacture of terephthalic acid for polyester. Its polymer is known as parylene.

Xylene is used as a solvent and in the printing, rubber, and leather industries. p-Xylene is used as a feedstock in the production of terephthalic acid, which is a monomer used in the production of polymers. It is also used as a cleaning agent for steel and for silicon wafers and chips, a pesticide [1], a thinner for paint, and in paints and varnishes.

Butanol or butyl alcohol (sometimes also called biobutanol when produced biologically), is a primary alcohol with a 4 carbon structure and the molecular formula of C₄H₁₀O. It belongs to the higher alcohols and branched-chain alcohols. ^[1]

n-Butanol or n-butyl alcohol (sometimes also called biobutanol when produced biologically), is a primary alcohol with a 4 carbon structure and the molecular formula of C₄H₁₀O. It belongs to the higher alcohols and branched-chain alcohols

2-Butanol, or sec-butanol, is a chemical compound with formula C₄H₁₀O. This secondary alcohol is a flammable, colorless liquid that is soluble in 12 parts water and completely miscible with polar organic solvent such as ethers and other alcohols.
