Isophthalic acid
Isophthalic acid (IPA), also known as 1,3-phthalic acid or isophthalic acid, has strong heat resistance, hydrolysis resistance and chemical resistance, and can undergo salt formation, dehydration, hydrogenation, halogenation and other reactions. Its biggest use is as an intermediate chemical book in the production of unsaturated polyester resins, followed by the manufacture of polyester resins, alkyd resins (mainly used in coatings) and printing inks. In addition, it can also be used to reinf...Read more -
Dimethyl terephthalate(DMT)
Chemical properties: Dimethyl phthalate is a white crystalline solid at room temperature and pressure, which contains two ester groups. These ester groups have strong electrophilicity and are easily attacked by nucleophilic reagents. Therefore, dimethyl phthalate can participate in a variety of nucleophilic reactions, such as ester hydrolysis under acid catalysis, nucleophilic substitution reaction, etc. Dimethyl phthalate can undergo ester exchange polycondensation reaction, hydrogenation an...Read more -
