aluminium sulfate

Aluminium sulfate is an industrial chemical used as a flocculating agent in the purification of drinking water and waste water treatment plants, and also in paper manufacturing. It is used as a mordant in dyeing and printing textiles. Aluminium sulfate is the active ingredient of some antiperspirants. It is usually found in baking powder, where there is controversy over its use due to concern regarding the safety of adding aluminium to the diet. In construction industry it is used as waterproofing agent and accelerator in concrete. Another use is a foaming agent in fire fighting foam. It is also used in styptic pencils, and pain relief from stings and bites. It can also be very effective as a molluscicide, killing spanish slugs.

m-Phenylenediamine is an aromatic amine. It is an isomer of o-phenylenediamine and p-phenylenediamine. It is used in the preparation various polymers including aramid fibers, epoxy resins, wire enamel coatings and polyurea elastomers. Other uses for m-phenylenediamine include as an accelerator for adhesive resins, and as a component for hair dyes and dyes for leather and textiles.

o-Cresol is a phenol. It is an isomer of p-cresol, m-cresol and anisole. Cresols are used to dissolve other chemicals, as disinfectants and deodorizers, and to make specific chemicals that kill insect pests. They are found in many foods and in wood and tobacco smoke, crude oil, coal tar, and in brown mixtures such as creosote, cresolene and cresylic acids, which are wood preservatives.

o-Phthalaldehyde is a dialdehyde consisting of two formyl groups attached to adjacent carbon centres on a benzene ring. It is a building block in the synthesis of heterocyclic compounds and a reagent in the analysis of amino acids. It is used as a disinfectant and as a tanning agent in leather industry. It is useful for the sterilization of endoscopic instruments, thermometers, rubber and plastic equipment which cannot be sterilized by heating system. It is also used as an intermediate in synthesis of pharmaceuticals, medicines, and other organic compounds.

p-Chloroaniline is a organochlorine compound. It is a precursor to the widely used antimicrobial and bacteriocide Chlorhexidine. p-Chloroaniline is prepared by hydrogenation of 4-nitrochlorobenzene, which in turn is prepared by nitration of chlorobenzene. p-Chloroaniline is an important building block used in the chemical industry for the production of pesticides, drugs, and dyestuffs. It is a precursor to the widely used antimicrobial and bacteriocide chlorhexidine and is used in the manufacture of pesticides, including pyraclostrobin, anilofos, monolinuron and chlorphthalim.

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.
