DMP(CAS no. 131-11-3) is the aromatic diester of methyl alcohol and phthalic acid, manufactured by catalytic esterification of methyl alcohol with phthalic anhydride.

DMP is a colourless, light fast, faint aromatic odoured liquid and finds applications as plasticizers for nitrocellulose and cellulose acetate resins. It yields excellent films having good adhesion with both, in proportions upto 75% of the weight of the cellulose ester. It also plasticizes rubber and Poly Vinyl Acetals. Other applications include Fiber Reinforced Plastics, solid rocket propellants, lacquer plastics, rubber coating agents, safety glass, molding powders, cement concrete additive, insect repellants and perfumery compounds.

Dimethyl Phthalate (DMP) (CH3)2{C6H4(COO)2} as per IS 6627 and JSS 6840-07

Diethyl Phthalate (DEP) {C6H4(COO.C2H5)2}

DEP (CAS  No. 84-66-2) is the aromatic diester of ethyl alcohol and phthalic acid, manufactured by catalytic esterification of ethyl alcohol and phthalic anhydride.

DEP enjoys wide popularity for lacquer work. It is a good wetting medium in which to grind solid pigments. It is also a good plasticizer for cellulose acetate, cellulose nitrate, ethyl cellulose, di-benzyl cellulose and Glyceryl Phthalate resins. It is a good solvent for ester gum, Cumarone, Benzyl Acetate, vinyl and Cyclohexanone-formaldehyde resins. It is used widely in the perfumery industries as a solvent and fixative, as an alcohol denaturant, camphor substitute and in insecticidal sprays.

Dibutyl Phthalate (DBP) {C16H22O4}

DBP (CAS No. 84-74-2) is the aromatic diester of n-butyl alcohol and phthalic acid, manufactured by catalytic esterification of n-butyl alcohol with phthalic anhydride.

DBP is a colourless to very pale yellow liquid with characteristic ester odour and finds extensive applications in nitro cellulose lacquers, elastomers, explosives, nail polish, as a solvent for perfumery oils and perfumery fixative, textile lubricating agent, safety glasses, insecticides as a mite repellant, printing inks, paper coating and adhesives and as a plasticizer for polystyrene, polyvinyl and methacrylate resins. It gives longer life to outside varnishes exposed to sunlight an weather and is often used to grind colouring matter intended for incorporation into films or plastic.
