When liquid o-xylene is mixed with liquid p-xylene, the solution formed is ideal at all compositions. Fire Extinguishing Agents Not to Be Used: Water may be ineffective. All sampling instructions above are recommended guidelines for OSHA Compliance Safety and Health Officers (CSHOs), please see the corresponding OSHA method reference for complete details. Results for unrequested analytes in this group will be reported if significant amount are found.

When liquid o-xylene is mixed with liquid p-xylene, the solution formed is ideal at all compositions. The experimental data shown in these pages are freely available and have been published already in the DDB Explorer Edition. The xylene isomers: m-xylene (1,3- Heat of Vaporization. Kidney and liver damage can occur. 1,2-Dimethylbenzene, ortho-Xylene, . 1 It is a colorless . Synonyms include dimethylbenzene, methyl toluene, xylol, and mixed xylenes. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
