Dimethyl phthalate Usage And Synthesis

Dimethyl phthalate	Dimethyl phthalate esters is a broad-spectrum, highly effective insect repellent, it is colorless to pale yellow transparent liquid, is an effective insect repellent ingredient in toilet water, it has a good repellent effect on flies, lice, ants, mosquitoes, cockroaches, midges, gadfly, flat fleas, sand fleas, sand midges, sandflies, cicadas; its repellent effect lasts for a long time, and it can be used in different climatic conditions . Under the conditions of using, it’s chemical stable, displaying both high thermal stability and high resistance to sweat. It has good compatibility with common cosmetic and pharmaceutical agents, can be made of solutions, emulsions, pastes, coating agents, gel, aerosol, mosquito coils, micro-capsules and other special repellent agents, and also can be added to other products or materials (such as toilet water), so that product displays the repellent effect as well. Compared with standard mosquito repellent agent and mosquito repellent gel, it is less toxic, and less irritating, with longer repellent time and other notable features, is a repellent gel replacement. The above information is edited by the chemicalbook of Tian Ye.
Toxicity	Dimethyl phthalate displays no toxicity or side effects on the skin and mucous membranes, non-allergic and non-skin-permeable etc., it is very safe to use, it is noted that people with sensitive skin may cause skin allergies reaction if repellent ester component is excessive absorbed .
Chemical Properties	Colorless oily liquid with a slightly aromatic fragrance. Immiscibility with ethanol, ethyl ether , soluble in organic solvents such as benzene, acetone, insoluble in water and mineral oil.
Application	1. It is used as a plasticizer for cellulose acetate, polyvinyl fluoride coating repellent agents and solvents. 2. Dimethyl Phthalate is rodenticide rat poison, rat finished, chlorine mouse ketone intermediates, it is also an important solvent. 3. The product is a plasticizer for variety of resin having a very strong dissolving power, is compatible with a variety of cellulose resin, rubber, vinyl resin. It displays good film-forming character, adhesion and water resistance. It is usually used with diethyl phthalate in cellulose acetate film, varnish, transparent paper and molding powder production . A small amount of the product is used in nitrocellulose production. The product can also be used as a nitrile rubber plasticizers, with good resistance to cold products. The product can be mixed with other plasticizers. It can overcome the high volatility , low-temperature crystallization and other shortcomings. The products are also used as DEET oil (crude oil) and DDT solvents. The product is also used as gas chromatography stationary phase.
Production method	Esterified under normal pressure with an excess amount of the anhydride (4-fold) in methanol, excess methanol was refluxed with water, DMP was obtained from the reaction. The 600kg anhydride, 450kg methanol 90-95 ℃', 1050ml concentrated sulfuric acid were added into the reaction pot successively, heated to reflux for 24h. After completion of the reaction, methanol recovery, then neutralized with sodium carbonate, washed with water, and then distilled to obtain the finished product. Industrial grade product dimethyl phthalate purity of ≥99%. Material consumption fixed: anhydride 750kg / t, methanol 445kg / t.
Category	Flammable liquid
Toxicity grading	Low toxicity
Acute toxicity	Oral - rat LD50: 6800 mg / kg; Oral - Mouse LD50: 6800 mg / kg
Irritation data	Eye - rabbit 119 mg
Flammability hazard characteristics	In the case of fire, high temperature, strong oxidants, it is combustible; combustion exhaust irritating smoke.
Storage feature	It should be stored in a complete package with care; warehouse ventilation, away from obvious flame, heat, and oxidants.
Extinguishing agents	Foam, carbon dioxide, dry powder, sand, water mist.
Chemical Properties	colourless oily liquid
Professional Standards	TLV-TWA 5 mg / m³; STEL 10 mg / m3
Usage	It is used as insect repellent.
Usage	Dimethyl Phalate is the methyl ester of phthalic acid. Dimethyl phthalate is an ectoparasiticide and has many other uses, including in solid rocket propellants, plastics, and insect repellents.
General Description	A water-white liquid without significant odor. Denser than water and insoluble in water. Hence sinks in water. Flash point 300°F. Eye contact may produce severe irritation and direct skin contact may produce mild irritation. Used in the manufacture of a variety of products including plastics, insect repellents, safety glass, and lacquer coatings.
Air & Water Reactions	Insoluble in water.
Reactivity Profile	Dimethyl phthalate reacts with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides. Can generate electrostatic charges by swirling or pouring [Handling Chemicals Safely, 1980. p. 250].
Health Hazard	Symptoms unlikely from any exposure.
Fire Hazard	Dimethyl phthalate is combustible.
