2,4-Dimethylphenol Chemical Properties,Uses,Production
Chemical Properties
2,4-Dimethylphenol is a clear colorless to yellow liquid or needle crystals. miscible with alcohol and ether, slightly soluble in water.It has a moderate mammalian oral toxicity and is a recognised irritant.
Physical properties
Colorless solid, slowly turning brown on exposure to air.
Uses
2,4-dimethylphenol is a fungicide and disinfectant with a variety of agricultural uses. It is also used in making wetting agent; dyestuffs; phenolic antioxidants; pharmaceuticals; rubber chemicals; lubricant ; gasoline additive and plasticizers.
Definition
ChEBI: 2,4-xylenol is a member of the class of phenols that phenol substituted by methyl groups at positions 2 and 4. It has a role as a disinfectant and a volatile oil component. It is a member of phenols and an aromatic fungicide. It derives from a hydride of a m-xylene.
Preparation
synthesis of 2,4-dimethylphenol: 2,4-Dimethylphenol is obtained by sulfonation, salting out, alkali melting and acidification of m-xylene.
General Description
2,4-dimethylphenol appears as colorless crystals or clear, dark amber liquid.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
2,4-Dimethylphenol is a very weak acid (pKa = 10.6) . Incompatible with acid chlorides, acid anhydrides, bases and oxidizing agents. Corrodes steel, brass, copper and copper alloys .
Health Hazard
2,4-Dimethylphenol is expected
to be an irritant of the eyes, mucous membranes,
and skin, by analogy to other phenols.
The oral LD50 for rats was 3.2 g/kg; the
dermal LD50 in mice was 1.04 g/kg.
Fire Hazard
2,4-Dimethylphenol is probably combustible.
Safety Profile
Poison by intravenous and intraperitoneal routes. Moderately toxic by ingestion and skin contact. Questionable carcinogen with experimental carcinogenic data. When heated to decomposition it emits acrid smoke and irritating fumes. See also other xylenol entries.
Carcinogenicity
2,4-Dimethylphenol was tested for mutagenicity
in the Salmonella microsome preincubation
assay using the standard protocol of the
National Toxicology Program and five strains
of Salmonella; results were negative.
The ACGIH has not established a threshold
limit value (TLV) for 2,4-dimethylphenol.
Environmental Fate
Biological. When 2,4-dimethylphenol was statically incubated in the dark at 25 °C with yeast
extract and settled domestic wastewater inoculum, significant biodegradation with rapid
adaptation was observed. At concentrations of 5 and 10 mg/L, 100 and 99% biodegradation,
respectively, were observed after 7 d (Tabak et al., 1981).
Photolytic. 2,4-Dimethylphenol absorbs UV light at a maximum wavelength of 277 nm
(Dohnal and Fenclová, 1995).
Chemical/Physical. Wet oxidation of 2,4-dimethylphenol at 320 °C yielded formic and acetic
acids (Randall and Knopp, 1980). 2,4-Dimethylphenol will not hydrolyze because there is no
hydrolyzable functional group (Kollig, 1993).
