Mixed xylene specific gravity
WebIt is a constitutional isomer of m -xylene and p -xylene, the mixture being called xylene or xylenes. o -Xylene is a colourless slightly oily flammable liquid. [7] Production and use [ edit] Petroleum contains about one weight percent xylenes. Web2 jul. 2024 · The specific gravity of xylene is the ratio of the density of xylene to that of a reference substance (Usually water). This information can be used to tell whether xylene will float (or sink) if dropped in water (Buoyancy). Formula SG = ρxylene / ρwater Note: Both densities need to be in the same unit as they will cancel each other and produce SG.

WebThe oral LD50 in rats was 3523 mg/kg/bw for males and greater than 4000 mg/kg/bw for females. In a single-administration study, groups of five F344/N rats of each sex received 500, 1,000, 2,000, 4,000, or 6,000 mg/kg. Administration of mixed xylenes caused deaths at 6,000 mg/kg in each sex and at 4,000 mg/kg in males. Mixed xylenes refers to a mixture of the xylenes plus ethylbenzene.
