ERSCHEINUNGSBILD
FARBLOSE VISKOSE FLüSSIGKEIT MIT CHARAKTERISTISCHEM GERUCH.
ARBEITSPLATZGRENZWERTE
TLV: 50 ppm (als TWA); (ACGIH 2005).
MAK: IIb (nicht festgelegt, aber Informationen vorhanden) (DFG 2005).
AUFNAHMEWEGE
Aufnahme in den K?rper durch Inhalation der D?mpfe, über die Haut und durch Verschlucken.
INHALATIONSGEFAHREN
Beim Verdampfen bei 20°C tritt eine gesundheitssch?dliche Kontamination der Luft nicht oder nur sehr langsam ein
WIRKUNGEN BEI KURZZEITEXPOSITION
WIRKUNGEN BEI KURZZEITEXPOSITION: Die Substanz reizt leicht die Augen und die Haut. Exposition gegenüber hohen Dampfkonzentrationen kann zu Reizung der Augen und der oberen Atemwege führen.
WIRKUNGEN NACH WIEDERHOLTER ODER LANGZEITEXPOSITION
Wiederholter oder andauernder Hautkontakt kann Dermatitis hervorrufen.
LECKAGE
Zündquellen entfernen. Ausgelaufene Flüssigkeit m?glichst in abdichtbaren Beh?ltern sammeln. Reste mit Sand oder inertem Absorptionsmittel aufnehmen und an einen sicheren Ort bringen. Pers?nliche Schutzausrüstung: Atemschutzfilter für organische Gase und D?mpfe.

Chemische Eigenschaften
2-Methylcyclohexanol is a straw-colored liquid.
Weak, menthol-like odor. The odor threshold is 490 ppm.
(higher than the OEL).
Verwenden
Methylcyclohexanol is used as a blendingagent in textile soaps as an antioxidant inlubricants, and as a solvent for lacquers.
Vorbereitung Methode
Methylcyclohexanol is produced by hydrogenating m- and
p-cresols. Methylcyclohexanol can exist as three
separate isomers, ortho, meta, and para, or as a mixture of
isomers. The commercial product consists essentially of the
meta and para isomers. Methylcyclohexanol is used as a
solvent in lacquers, a blending agent in textile soaps, and an
antioxidant in lubricants. In addition, methylcyclohexanol
dissolves gums, oils, resins, and waxes.
Allgemeine Beschreibung
Colorless viscous liquids with a menthol-like odor. Less dense than water. Flash point 136°F. Vapors heavier than air. May be toxic by ingestion. Used as a solvent and to make soaps and detergents.
Air & Water Reaktionen
Flammable. Soluble in water.
Reaktivit?t anzeigen
METHYLCYCLOHEXANOL is incompatible with the following: Strong oxidizers .
Hazard
Toxic by ingestion. Eye and upper respira-tory tract irritant.
Health Hazard
Methylcyclohexanol is mildly toxic. Inhalationmay produce mild irritation of the eyesand the respiratory system, and headache.Studies in rabbits showed that this compoundcould cause rapid narcosis and convulsion atsublethal doses. The minimum lethal dose byoral administration was 2000 mg/kg. Severeexposure may produce narcosis in humans.Skin absorption may cause dermatitis.
Brandgefahr
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Sicherheitsprofil
Moderately toxic by
ingestion and subcutaneous routes. Mildly
toxic by skin contact. Human system effects
by inhalation: antipsychotic, unspecified
liver and kidney effects. Combustible when
exposed to heat, flame, or oxidizers. On
heating it emits acrid fumes; can react with
oxidizing materials. To fight fire, use alcohol
foam, CO2, dry chemical.
m?gliche Exposition
Methylcyclohexanol is used as a lacquer solvent; as a blending agent in textile soaps and as an
antioxidant in lubricants.
Versand/Shipping
UN2617 Methylhexylhexanone, flammable,
Hazard Class: 3; Labels: 3-Flammable liquid.
Inkompatibilit?ten
Vapors may form explosive mixture with
air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep
away from alkaline materials, strong bases, strong acids,
oxoacids, epoxides. Attacks some plastics, rubber, and
coatings.
Waste disposal
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed
