Plasticizers: Synthesis of phthalate esters via FeCl3
Plasticizers are the substances used to increase flexibility, transparency, durability and longevity of the plastics. Phthalates are also used as lubricant, stabilizer, binder and adhesive [3]. They are also used to manufacture toys, textiles, paints, medical devices, cosmetics, etc.
Palatinol M
+55 11 2039-3351 Send email Chemical nature: Dimethyl phthalate, phthalic acid dimethyl ester Palatinol M is a nearly colourless, clear and practically anhydrous liquid with a hardly noticeable odour. It is soluble in the usual organic solvents and is miscible and compatible with all of the monomeric plasticizers commonly used in PVC.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Di-2-ethylhexyl-phthalate (DEHP, formula: C 6 H 4 (C 8 H 17 COO) 2) is a low molecular weight ortho-phthalate produced by esterification of phthalic anhydride with 2-ethyl-hexanol. It is non-volatile, colorless and odorless viscous liquid, soluble in oil, but not in water.
Phthalate Ester - an overview | ScienceDirect Topics
Phthalate acid esters (PAEs) are a class of chemical compounds widely used in different industrial applications, mainly as plasticizers for polyvinyl chloride (PVC) resins, adhesives and cellulose film coatings and with minor applications in cosmetics, medical products and insecticide carriers.
Plasticizer - an overview | ScienceDirect Topics
Specialist plasticisers include phosphates for fire retardancy, polymeric plasticisers (low migration) and some newer ‘non-phthalate’ plasticisers such as citrates, benzoate esters, alkyl sulphonic phenyl esters (Mesamoll), di-isononyl cyclohexane-1,2-dicarboxylate (Hexamoll DINCH) and biobased plasticisers (e.g. Grindsted Soft-n-Safe).
- Is dimethyl phthalate a good plasticizer for PVC?
- Unlike most other phthalate esters, dimethyl phthalate is rarely used as a plasticizer for PVC. It is considered too volatile and causes excessive fuming during PVC processing. It is a good plasticizer for cellulose-esters, including cellulose acetate, cellulose acetate butyrate and cellulose propionate compositions.
- Is dibutyl phthalate used as a plasticizer?
- Plasticizers are chemical additives that improve the plasticity of a polymer and are widely used, including in food packaging materials. One common phthalate plasticizer is dibutyl phthalate (DBP). A method to detect the presence of DBP in food samples is urgently needed.
- What are phthalate plasticizers & parabens?
- For serious health problems to arise, exposure to these rapidly-clearing compounds must occur on a daily basis. Two such classes of compounds are the phthalate plasticizers and parabens, both of which are used in many personal care products, some medications, and even foods and food preservation.
- Is dimethyl phthalate soluble in water?
- Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?
- ) Dimethyl phthalate (DMP) is an organic compound and phthalate ester. it is a colourless and oily liquid that is soluble in organic solvents, but which is only poorly soluble in water (~4 g/L).
- How is dimethyl phthalate made?
- Dimethyl phthalate is manufactured commercially via the esterification of phthalic anhydride with methanol. The reaction can be catalysed by a strong acid, such as sulfuric acid; various lewis acids may be used as an alterative, including complexes of titanium, zirconium or tin.
- How much monomethyl phthalate (DMP) is toxicity?
- After an orally administered dose of 0.1mL of DMP, about 77% of monomethyl phthalate and 8% of DMP have been detected in urine collected for 24 hours from male rats. Acute oral toxicity results in an LD50 of 8,2, 5,2, 2,9, 10,1 and 8,6 mg/kg for rats, rabbits, guinea pigs, chicks, and mice respectively.
