Troysan Polyphase Af1

Troysan Polyphase Af1 is used as an fungicide in cutting oils, textiles, paper cutting, adhesives.

sodium hydrosulfite

This compound is a water-soluble salt, and can be used as a reducing agent in aqueous solutions. It is used as such in some industrial dyeing processes, where an otherwise water-insoluble dye can be reduced into a water-soluble alkali metal salt. The reduction properties of sodium dithionite also eliminate excess dye, residual oxide, and unintended pigments, thereby improving overall colour quality.

Sodium dithionite can also be used for water treatment, gas purification, cleaning, and stripping. It can also be used in industrial processes as a sulfonating agent or a sodium ion source. In addition to the textile industry, this compound is used in industries concerned with leather, foods, polymers, photography, and many others. Its wide use is attributable to its low toxicity LD50 at 5 g/kg, and hence its wide range of applications. It is also used as decolourising agent in organic reactions.

1 Chloro Anthraquinone

1-Chloro anthraquinone can be used as a dye intermediate. such as dyes of Vat Brown BR. Its derivatives are widely used as intermediates for dyes, pigments, photographic chemicals, and paints. Anthraquinone is used in paper industry as a catalyst to increase the pulp production yield and to improves the fiber strength through reduction reaction of cellulose to carboxylic acid.

1,2,3-Trimethylbenzene

1,2,3-Trimethylbenzene is mainly used for the preparation of aniline dyes, alkyd resins, polyester resins.

1,2,4-Trichlorobenzene

1,2,4-Trichlorobenzene used as solvent in chemical manufacturing, dyes & intermediates, dielectric fluid, synthetic transformer oils, lubricants, heat-transfer medium, insecticides.

1,8-Dinitronaphthalene

1,8-Dinitronaphthalene is an intermediate for colorants and other organic synthesis.

2-Amino-5-Methylphenol

2-Amino-5-methylphenol is used as a precursor for hair colours. It reacts with primary intermediates to form the final dye-stuff.

2-Ethyl-1,3-hexanediol

2-Ethyl-1,3-hexanediol is used as a solvent for inks, plasticizer, chemical intermediate in production of polyurethane resins, and insect repellent.

3,3'-Dimethylbenzidine

3,3'-Dimethylbenzidine is a commercially important aromatic amines used mainly for dye production, but also for the production of certain elastomers. It is also widely used as a reagent or indicator in analytical, clinical and forensic chemistry, such as in the analytical determination of gold. It is used as an intermediate for the production of soluble azo dyes and insoluble pigments used particularly in the textile, leather and paper industries.

4-Amino-2-Nitrotoluene

4-Amino-2-Nitrotoluene is a orange crystalline solid with pleasant aroma. It is used as intermediate for dyes and pigments, because of its aroma it is used in flavour and fragrance industry.
