Exploring Peri Acid

Peri acid (CAS no. 82-75-7) is used in vat dyes, specialized textile dyes, and many other dye products. Apurva Chemicals, one of India's most reliable Peri Acid producers, is proud to provide high-purity industrial Peri Acid for global markets, including Germany, the USA, and other textile manufacturing centers.

This blog will explore Peri Acid's properties, applications, benefits, and importance in dye production and quality control. We also provide insights on international compliance and standards.

Peri Acid: What is it?

Peri Acid, also known chemically as 1,8-Naphthalic Anhydride-4-sulfonic Acid, plays an important role in vat dye synthesis. The yellow powder is used to create high-performance, colorfast dyes.

CAS Number: 82-75-7
Molecular Formula: C12H6O5S
Appearance: Yellow crystalline powder
Solubility: Slightly water soluble
Grade: Industrial grade
Applications: Dye intermediate, particularly for vat dyes

Production of VAT dyes with Peri-Acid

The most common type of vat dye is used for cotton and other cellulose-based fibers. Peri Acid plays a major role in the production of vat dyes based on anthraquinone, which is washable and lightfast.

Peri Acid: Why it is Important in Dye Manufacturing:

This molecule acts as a Sulfonating Agent and modifies dye molecules for better solubility.
Allows for the creation of intense, bright shades onto textile substrates.
Improvements in chemical stabilité performance of the dye.

Peri Acid is a dye intermediate that must adhere to strict specifications to maintain color consistency and uniformity.

Contributions of India

India has a robust chemical manufacturing capability, a skilled workforce, and a dependable infrastructure. It is also regarded as a major producer of dye intermediates. The facility is a modern factory that produces Peri Acid in India for domestic and international markets.
