APPLICATIONS

Phthalates are by far the most widely used plasticisers, primarily to make soft and flexible polyvinyl chloride (PVC) for the applications in the industry of automotive, building & construction material, cable, flooring, medical device and toys. Phthalates make the long polyvinyl molecules to slide against one another. Minor quantity of phthalates are used in adhesives, caulk, sealants, paint to improve work performance. Small molecule phthalates are used as solvents in perfumes to provide longer linger longer and in nail polish to prevent chipping. They are also used as ingredients of insect repellents, as solvents in lacquer and pesticides, and as dye carrier. They are used as textile lubricating agents and as solid rocket propellents. Phthalates are produced by the reaction of phthalic anhydride with appropriate alcohols from methanol up to isodecanol (C13), either as a straight chain or with some branched in the presence of concentrated sulphuric acid as a catalyst. Excess alcohols are recovered and recycled and phthalates are purified by vacuum distillation and/or activated charcoal. A wide range of phthalates of varying chain length and structure provides each adequate properties and cost-effective for various processing and mechanical requirements. C8 - C9 phthalates, such as di-2-ethyl hexyl phthalate (DEHP or called DOP), diisodecyl phthalate (DIDP) and diisononyl phthalate (DINP) are the most widely used general purpose phthalates. DOP is the dominant plasticizer used in PVC, providing low cost. Short chain phthalates (C3 - C7) are used when rapid setting and stain resistance is required. 2-Ethyl hexanol, produced by the dimerisation of butyraldehyde obtained from propylene, is cheaper than isononyl alcohol which are prepared by the carbonylation of an olefin. Long chain phthalates (C11 - C13) are used when high temperature stability is required. C1 and C2 phthalates are used as solvents. Special phthalates which contain aromatic ring in the side chain are used when fast-fused is required. Diallyl phthalate is used as a crosslinking agent, plasticizer or dying carrier for polyesters. Examples of common phthalates include:

GENERAL DESCRIPTION OF CYCLOHEXANE

Cyclohexane is the six-membered alicyclic hydrocarbon consisting of six carbon atoms linked to each other to form a ring, with each carbon atom bearing two hydrogen atoms, C6H12. A cyclic compound is an organic compound that contains one or more closed rings of carbon atoms. The term alicyclic refers to cyclic compound that behaves chemically like aliphatic compounds (open-chain), which means the exclusion of carbocyclic compounds of aromatic rings with an array of -electrons characteristic. Cyclohexane is a colorless, highly flammable, mobile liquid with a pungent odor. It is insoluble in water and soluble in alcohol, ether, and almost organic solvents. Cyclohexane is a non-corrosive and quick volatilize liquid and sublimes between -5 to 5 C. Cyclohexane can exist in a number of  interconvertible three-dimensional conformations, the two simplest being are the chair and boat conformation and others include the half-chair and twist-chair conformation. Cyclohexane can cause irritation to the eyes and mucous membranes in workers. Repeated and prolonged contact with skin may cause dermatitis. The substance has not been shown to cause the hematologic changes associated with exposure to benzene. Cyclohexane occurs naturally in crude oils. Some cyclohexane is recovered from petroleum streams by fractionation. The bulky commercial  production of cyclohexane is based on hydrogenation of benzene in closed system. Cyclohexane consumption is linked almost entirely to nylon production. Nylon is further processed into fibers for applications in carpeting, automobile tire cord, clothing, and other growing industrial fields. Cyclohexane is used as a solvent, oil extractant, paint and varnish remover, dry cleaning material, and in solid fuels. It has been used as a insecticide itself. Cyclohexane is used as a chemical intermediate to produce target molecules. Natural compounds of one to five alicyclic rings with great variety and complexity are found particularly in steroids and terpenes. Cyclohexane structure, six membered-ring, is one of the major skeleton in nature. Cyclohexane derivatives can be used for the synthesis of pharmaceuticals, dyes, herbicides, plant growth regulator, plasticizers, rubber chemicals, cycloamines and other organic compounds.
