The CRC Handbook (Lide, 2008) is a peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint. The melting point of the xylene isomers ranges from -47.8 to 13.25˚C at standard pressure. The general uncertainties of the equations of state are 0.5% in vapor pressure above the normal boiling point, and The melting point of m- xylene is -47.8˚C, for o- xylene is -25.2˚C and is 13.25˚C for p- xylene. Therefore, p-xylene molecules have comparatively a strong attraction force between them, which makes it difficult to separate the molecules from each other. The boiling point for each isomer is around 140 °C (284 °F). The melting point of m- xylene is -47.9 ˚C, for o- xylene it is -25.5˚C, for p-xylene it is 13.2˚C, and for ethylbenzene it is -94.96°C. The melting point of the xylene isomers and ethylbenzene range from -94.96 to 13.2˚C at 1013hPa. Xylenen. Chromatogr., 14, 1991, 601-607. The melting point ranges from −47.87 °C (m-xylene) to 13.26 °C (p-xylene). Melting point: o-xylene m-xylene p-xylene techn. The melting point of the three isomers ranges is −25 °C for o-xylene, −47.87 °C for m-xylene and 13.26 °C for p-xylene. The density of each is around 0.87 g/mL and thus is less dense than water.

The melting point ranges from −47.87 °C (−54.17 °F) (m-xylene) to 13.26 °C (55.87 °F) (p-xylene)—as usual, the para isomer's melting point is much higher because it packs more readily in the crystal structure. Equations of state for the xylene isomers (o-xylene, m-xylene, and p-xylene) and ethyl-benzene have been developed with the use of the Helmholtz energy as the fundamental property with independent variables of density and temperature. *Please select more than one item to compare Xylenes, ACS reagent, >=98.5% xylenes + ethylbenzene basis The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). The chemical and physical properties of xylene differ according to the respective isomers. It is a constitutional isomer of m -xylene and p -xylene , the mixture being called xylene or xylenes. The density of each isomer is around 0.87 g/mL (7.26 lb/U.S. 【Melting Point】 > -34 【Boiling Point】 140 【Vapor Pressure】 8 【Density】 1.096 g/cm3 【Partition Coefficient】 3.12-3.20 【Usage】 Aviation gasoline; protective coatings; solvent for alkylated resins, lacquers, enamels, rubber cements; synthesis of organic chemicals. Res. The xylenes are for the most part manufactured and marketed as a mixture of the isomers, which will here be called xylene.

The p-xylene is then separated out in a series of distillation, adsorption or crystallization and reaction processes from the m-xylene, o-xylene, and ethylbenzene. CopyCopied, FVHAWXWFPBPFOS-UHFFFAOYSA-N Articles of neo-clear(r) xylene … Search results for xylene at Sigma-Aldrich. It is because the methyl groups in p-xylene are separated in such a way that there is less strain in the molecule. Xylene is used in the form of a raw material in the manufacturing of fibres, films, and dyes. Chemsrc provides neo-clear(r) xylene substitute(CAS#:8052-41-3) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Welcome to the ECHA website.
