개요
Isophthalic acid is an organic compound with the formula C6H4(CO2H)2. This colourless solid is an isomer of phthalic acid and terephthalic acid. These aromatic dicarboxylic acids are used as precursors (in form of acyl chlorides) to commercially important polymers, e.g. the fire-resistant material Nomex. Mixed with terephthalic acid, iso phthalic acid is used in the production of resins for drink bottles. The high-performance polymer poly benzimidazole is produced from iso phthalic acid.화학적 성질
Isophthalic acid is a white crystalline powder or needle-like crystals and it’s an isomer of phthalic acid and terephthalic acid.It is insoluble in cold water but soluble in oxygenated solvents and alcohol. It is combustible and finely dispersed particles will form explosive mixtures in air.
Isophthalic Acid (PIA) is mainly used in the production of bottle PET, also used in the production of alkyd resin, polyester resin, also used in the production of photosensitive materials, pharmaceutical intermediates and so on.
One of the largest applications for PIA is in unsaturated polyester resins for high-quality gel coats. The hardness, stain and detergent resistance characteristics of PIA are ideal for polyester solid-surface countertops that are an inexpensive alternative to acrylics.
용도
Purified Isophthalic Acid (PIA) is mainly used as intermediate for high performance UPR, resins for coatings, high solids paints, gel coats, modifier of PET for bottles. Product Data Sheet제조 방법
Iso phthalic acid is produced on the billion kilogram per year scale by oxidizing meta-xylene using oxygen . The process employs a cobalt-manganese catalyst. In the laboratory, chromic acid can be used as the oxidant. It also arises by fusing potassium meta-sulpho benzoate , or meta - brom benzoate with potassium formate (terephthalic acid is also formed in the last case).The barium salt (as its hexa hydrate) is very soluble (a distinction between phthalic and terephthalic acids). Uvitic acid, 5- methylisophthalic acid, is obtained by oxidizing mesitylene or by condensing pyroracemic acid with baryta water.
