1. P-tert-butyl phenol usually replaces n-butanol as solvent for paints and drugs. Used as a fuel additive in internal combustion engines (to avoid carburetor freezing) and as an antiknock agent. As intermediates in organic synthesis and alkylation raw materials for the preparation of tert-butyl compounds, methyl methacrylate, p-tert-butyl phenol can be prepared for the synthesis of drugs and spices. Dehydration of tert-butylphenol can produce isobutene with a purity of 99.0-99.9%. It is used as a solvent for industrial washers, pharmaceutical extractants, insecticides, solvents for waxes, cellulose esters, plastics and paints, as well as for the consumption of denaturing alcohols, perfumes, fruit flavors, isobutene, etc.

2. Solvent is used for molecular weight determination and chromatographic analysis of reference substances. In addition, n-butanol is commonly used as a solvent in paints and medicines.

3, used as a solvent, chromatographic specification.

4, for perfume synthesis.

5, used as fuel additive for internal combustion engine (avoid carburetor freezing) and antiknock agent. As intermediates in organic synthesis and alkylated raw materials for the preparation of tert-butyl compounds, methyl methacrylate, tert-butyl amine can be prepared for the synthesis of drugs and spices.
