Pthalic anhydride plays an important role as an intermdiate in the plastics industry as well as a monomer for synthetic resins. EINECS 211-373-6. The common name of the 1,2-benzene dicarboxylic acid is phthalic acid.Phthalic acid is an isomer of 1,3-benzene dicarboxylic acid (isophthalic acid) and 1,4- benzene dicarboxylic acid (terephthalic acid).The physical properties of the substance. Data Program, but require an annual fee to access. Burriel, F., Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a 3-nitrophtalic acid anhydride. Thermochim. 4-nitrophthalicanhydride. Witschonke, C.R., The primary use of phthalic anhydride is a precursor to phthalate esters, used as plasticizers in vinyl chloride. These phthalic anhydride manufacturing companies … The major subsequent product groups are plasticizers (56%), unsaturated polyester resins (17%), and alkyd resins (17%). Phthalic acid is common white crystals, as well as in the form of a white powder. The process begins with the reaction of phthalic anhydride with alcohols, giving the monoesters: Molecular Weight: 148.12 . 3-nitro-phtalic anhydride. As a kind of biomass nanofiller for polymers, cellulose nanocrystal (CNC) has good mechanical properties and reinforcing capability. The Melting of Binary Eutectics, Bull.
