Usage

Description

5,5'-Dichloro-4,4',7,7'-tetramethyl-2,2'-bibenzo[b]thiophene-3,3'-diol bis(sulfuric acid sodium) salt is a brilliant red light purple to purple red powder that is soluble in water, resulting in a red light purple solution. 5,5'-Dichloro-4,4',7,7'-tetramethyl-2,2'-bibenzo[b]thiophene-3,3'-diol bis(sulfuric acid sodium) salt is known for its use as a dye in the textile industry, particularly for cotton fabric, due to its ability to produce a brilliant red light purple color.

Uses

Used in Textile Industry:
5,5'-Dichloro-4,4',7,7'-tetramethyl-2,2'-bibenzo[b]thiophene-3,3'-diol bis(sulfuric acid sodium) salt is used as a dye for cotton fabric to achieve a brilliant red light purple color. It is also suitable for direct printing and resist printing on cotton fabric, as well as for dyeing silk, wool, and polyester/cotton blended fabrics.
Standard:
The compound meets various industry standards for fastness and performance, including:
Ironing Fastness: ISO 4, AATCC 5
Chlorine bleach: ISO 5, AATCC 5
Light Fastness: ISO 5, AATCC 5
Mercerized: ISO 3, AATCC 3-4
Oxygen bleach: ISO 4, AATCC 4
Soaping: ISO 4-5, AATCC 4
Fading: ISO 5, AATCC 5
Stain: Not specified
These standards ensure that the dye maintains its color and quality under various conditions, such as exposure to heat, light, and different types of bleach.

Preparation

(a) in the presence of Pyridine , with Chlorosulfonic acid treatment C.I. Vat Violet 3 leuco; (b) in the Pyridine with metal (such as copper, iron, zinc, etc) and Sulfur trioxide source (such as Sulfur trioxide, Chlorosulfonic acid or Methyl chlorosulfonate, etc.) processing C.I. Vat Violet 3. The above two kinds of situation after alkaline, filter out insolubles, remove Pyridine and salting out.
