DIETHYLHEXYL MALEATE

CAS Number:   142-16-5
Chem/IUPAC Name:   Bis(2-ethylhexyl)maleate
EINECS/ELINCS No:   205-524-5

DESCRIPTION:
DIETHYLHEXYL MALEATE is the chemical compound with the structural formula (H3C(−CH2)3−CH(−CH2−CH3)−CH2−O−C(=O)−CH=)2, where the two carboxylate groups are mutually cis.

DIETHYLHEXYL MALEATE can be described as the double ester of maleic acid with the alcohol 2-ethylhexanol.
DIETHYLHEXYL MALEATE is commonly called dioctyl maleate (DOM), reflecting the older usage of "octane" to refer to any 8-carbon alkane, straight-chained or branched.

DIETHYLHEXYL MALEATE is manufactured by treating 2-ethylhexanol with maleic anhydride and an esterification catalyst.
DIETHYLHEXYL MALEATE is a key intermediate raw material in the production of dioctyl sulfosuccinate (DOSS, docusate) salts, used medically as laxatives and stool softeners, and in many other applications as versatile surfactants.

DIETHYLHEXYL MALEATE is a light, water white lipophilic ester that exhibits exceptional performance properties in both Skin Care and Hair Care formulations.
DIETHYLHEXYL MALEATE provides excellent moisturization benefits to skin and hair as well as imparting shine.
DIETHYLHEXYL MALEATE is a clear, virtually colorless liquid with an ester-like odor.

DIETHYLHEXYL MALEATE is miscible with methanol, ethanol, acetone, diethyl ether, N,N-dimethylformamide and toluene, but not with water and aliphatic hydrocarbons.
DIETHYLHEXYL MALEATE contains about 1%-5% fumaric acid di (2-ethylhexyl) ester and 1%-2% alkoxysuccinic acid di (2-ethylhexyl) ester.
Under the action of heat and in the presence of acids or bases, DIETHYLHEXYL MALEATE reacts to form fumaric acid dialkyl ester.

USES OF DIETHYLHEXYL MALEATE:
DIETHYLHEXYL MALEATE can be used in organic synthesis, like the production of derivatives of succinic acid.
DIETHYLHEXYL MALEATE is also used as a comonomer in vinyl and acrylic emulsion polymerization for paints and adhesives.

SAFETY INFORMATION ABOUT DIETHYLHEXYL MALEATE:
FIRST-AID MEASURES:
General Advice Provide this SDS to medical personnel for treatment.
Eye Contact In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid.

Skin Contact:
In case of contact, flush skin with plenty of water.
Remove contaminated clothing and shoes.
Get medical aid if irritation develops and persists.
Wash clothing before reuse.

Inhalation:
If inhaled, remove to fresh air.
If not breathing, give artificial respiration.
If breathing is difficult, give oxygen.
Get medical aid.

Ingestion:
Do not induce vomiting without medical advice.
Call a physician immediately.
Most important symptoms and effects:

Symptoms:
Inhalation: may include nasal discharge, hoarseness , coughing, chest pain and breathing difficulty.
Skin: redness or discoloration, swelling, itching.
Burning or blistering of skin.

Eyes: eye irritation or burning sensation.
Ingestion: Essentially non--toxic; nausea , vomiting , loss of appetite gastrointestinal irritation and / or diarrhea.
Indication of any immediate medical attention and special treatment needed
Notes to Physician: Treat symptomatically.

FIRE-FIGHTING MEASURES:
Suitable Extinguishing Media:
Foam , Dry chemical , Carbon dioxide (CO2).
Unsuitable Extinguishing Media:
Do not use a solid water stream as it may scatter and spread fire.
Hazardous Combustion Products:

Under conditions of incomplete combustion, hazardous gases produced may consist of carbon monoxide and carbon dioxide (CO2).
Combustion gases of organic materials must in principle be graded as inhalation poisons.
Protective equipment and precautions for firefighters:
As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear.

Cool containers/ tanks with water spray.
ACCIDENTAL RELEASE MEASURES:
Personal precautions, protective equipment and emergency procedures
Personal Precautions:
Wear protective clothing.
Provide adequate ventilation.

For Emergency Responders:
Keep unnecessary people away, isolate hazard area and deny entry.
Stay upwind; keep out of low areas.
Isolate for 800 meters or 0.5 miles in all directions if tank, rail car, or tank truck is involved in fire. Evacuate downwind areas as conditions warrant to prevent exposure and to allow vapors or fumes to dissipate.

Spills may expose downwind areas to toxic or flammable concentrations over considerable distances in some cases.
Environmental Precautions:
Contain contaminated water/firefighting water.
Do not discharge into drains/surface waters/groundwater.
Methods and material for containment and cleaning up:
Methods for Containment:
Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder,sawdust).

Methods for Clean-Up:
Sweep up absorbed material and shovel into suitable containers for disposal.
Discard any product, residue, disposable container or liner in full compliance with federal, state, and
