TCPA as Intermediate for Pigment Yellow 138
Product Introduction
TCPA (Tetrachlorophthalic anhydride) is a key intermediate for producing Pigment Yellow 138. Our production process is simple and easy to control, without complicated steps. We use regular phthalic anhydride as the starting material, through gentle chlorination and basic purification, so the product works perfectly for making Pigment Yellow 138. This TCPA pigment yellow 138 intermediate, which is widely used in plastic coloring, printing inks and high-end coatings.
Product Details
Our TCPA is a white crystalline powder with no caking at all. It dissolves and mixes smoothly with other raw materials during the synthesis of Pigment Yellow 138. It has a molecular formula of C₈Cl₄O₃, molecular weight 285.89, stable melting point at 254–256℃, and purity higher than 99%. As TCPA pigment yellow 138 intermediate, it reacts with aromatic amines and other materials to form a stable pigment structure. This gives the pigment bright color, good light resistance and low fading tendency. It is very suitable for high-grade Pigment Yellow 138 used in automotive coatings and food packaging printing.
