Emulsion atom transfer radical polymerization of 2-ethylhexyl methacrylate:
The emulsion atom transfer radical polymerization (ATRP) of 2-ethylhexyl methacrylate (EHMA) was carried out with ethyl 2-bromoisobutyrate (EBiB) as an initiator and copper bromide (CuBr)/4,4′-dinonyl-2,2′-bipyridyl (dNbpy) as a catalyst system.

Production of 2-Ethylhexyl Methacrylate:
2-Ethylhexyl Methacrylate (2-EHMA) is an ester of Methacrylic acid.

Preparation of 2-Ethylhexyl Methacrylate:
Racemic 2-ethylhexyl acrylate can be prepared with a high yield by esterification of acrylic acid with racemic 2-ethylhexanol in the presence of hydroquinone as a polymerization inhibitor and a strong acid such as methanesulfonic acid by reactive distillation using toluene as an azeotroping agent.

Methods of Manufacturing of 2-Ethylhexyl Methacrylate:
The methacrylates can be synthesized by catalytic oxidation of isobutylene and subsequent esterification with the appropriate alcohol, or by reacting acetone with hydrocyanic acid and subsequent esterification in sulfuric acid with the appropriate alcohol.

Polymerization of 2-Ethylhexyl Methacrylate:
The substance may polymerize due to warming.

Methyl methacrylate, and in general the methacrylic esters, polymerize much less readily than the corresponding ordinary acrylates. 
None the less, they are stabilized by adding hydroquinone or pyrogallol, particularly in the presence of metallic copper.

Analytic Laboratory Methods of 2-Ethylhexyl Methacrylate:
Thin-layer chromatography (TLC), polarography, and spectrometry are used for soln measurements. 

Methacrylates in air have been analyzed by TLC, polarography, and colorimetry. 
Polarography has been used for determination of any residual monomer in the polymer.

Metabolism/Metabolites of 2-Ethylhexyl Methacrylate:
Small quantities of methacrylates may readily be metabolized by saponification into the alcohol and methacrylic acid. 
The latter may form an acetyl-coenzyme A derivative, which then enters the normal lipid metabolism. 

Acrylates and methacrylates are detoxified predominantly via conjugation with glutathione via the Michael addition reaction or glutathione-S-transferase. 
They are also likely to be hydrolyzed via carboxylesterases. 
The lower molecular weight esters are rapidly metabolized and eliminated, therefore, will not likely cause cumulative toxicity.

Properties of 2-Ethylhexyl Methacrylate:
2-Ethylhexyl acrylate polymerizes easily. 
The polymerization can be initiated by light, peroxides, heat, or contaminants. 

2-Ethylhexyl Methacrylate can react violently when combined with strong oxidants and can form explosive mixtures with air at temperatures above 82 °C (180 °F). 
The chemical, physical, and toxicological properties, however, can be greatly modified by additives or stabilizers.

Handling and Storage of 2-Ethylhexyl Methacrylate:

Safe Storage of 2-Ethylhexyl Methacrylate:
Cool. 
Store only if stabilized.

Storage Conditions of 2-Ethylhexyl Methacrylate:
To avoid photoinitiation of polymerization, all methacrylates should be stored with minimal exposure to light.

The effectiveness of phenolic inhibitors is dependent on the presence of oxygen and the monomers must be stored under air rather than an inert atmosphere. 
Temp must be kept low to minimize formation of peroxides and other products. 
Moisture may cause rust-initiated polymerization. 

Packaging of 2-Ethylhexyl Methacrylate:
2-Ethylhexyl Methacrylate (2-EHMA) is available in bulk in ISO tank-container or packed in drums or IBC.

Stability of 2-Ethylhexyl Methacrylate:
2-Ethylhexyl Methacrylate (2-EHMA) is stable but may polymerize upon exposure to light. 

2-Ethylhexyl Methacrylate stabilized with hydroquinone monomethyl ether. 
2-EHMA is heat sensitive and incompatible with strong acids, strong oxidizing agents and strong bases.

Reactivity of 2-Ethylhexyl Methacrylate:
2-Ethylhexyl Methacrylate (2-EHMA) forms homopolymers and copolymers.
Copolymers of 2-Ethylhexyl Methacrylate (2-EHMA) can be prepared with (meth)acrylic acid and 2-Ethylhexyl Methacrylate salts, amides, and esters, and with (meth)acrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, unsaturated polyesters and drying oils, etc. 

2-Ethylhexyl Methacrylate (2-EHMA) is also a very useful feedstock for chemical syntheses because 2-Ethylhexyl Methacrylate readily undergoes addition reactions with a wide variety of organic and inorganic compounds

Physical Dangers of 2-Ethylhexyl Methacrylate:
Vapours are uninhibited and may polymerize in vents or flame arresters, causing blockage.

Explosive Limits and Potential of 2-Ethylhexyl Methacrylate:
2-Ethylhexyl Methacrylate polymerizes exothermically in the presence of heat, contamination, oxygen free atmosphere, free radicals, peroxides, and inhibitor depletion liberating heat.

Stability/Shelf Life of 2-Ethylhexyl Methacrylate:
Storage of 2-Ethylhexyl Methacrylate at elevated temperatures (>30 °C or >85 °F) reduces the shelf-life. 
The typical shelf-life for 2-Ethylhexyl Methacrylate is 12 months.

Transportation and storage avoid shine rain and high temperature in transportation.
Store the products in cool, shady and ventilated conditions, keep far away from fire
6 months from date of delivery at maximum storage temperature of 30.

First Aid of 2-Ethylhexyl Methacrylate:
Fresh air, rest.

Fire Fighting of 2-Ethylhexyl Methacrylate:
Use water spray, powder, alcohol-resistant foam, carbon dioxide.

Spillage Disposal of 2-Ethylhexyl Methacrylate:    
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance.

Disposal Methods of 2-Ethylhexyl Methacrylate:    
The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. 
Recycle any unused portion of the material for 2-Ethylhexyl Methacrylate approved use or return it to the manufacturer or supplier. 

Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Preventive Measures of 2-Ethylhexyl Methacrylate:
When designing a safe plant, among other important considerations, 2-Ethylhexyl Methacrylate is necessary to be aware of the considerable exothermic heat generated in some reactions. 

Thus, high pressure and temperatures may develop. 
Dangerous exposures can be avoided with careful design such as completely enclosing those processes where toxic chemical or intermediates occur.

Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. 
Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. 
Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

Employees should be instructed about the necessity of cleansing the skin if 2-Ethylhexyl Methacrylate is contaminated by materials which are irritants or skin-absorbed.

The scientific literature for the use of contact lenses in industry is conflicting. 
The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. 

However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. 
In those specific cases, contact lenses should not be worn. 
In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Wear protective gloves to prevent skin exposure. 
If contact occurs, remove contaminated clothes; rinse and then wash skin with water and soap. 

Wear safety glasses to prevent eye exposure. 
If contact occurs, first rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. 
Do not eat, drink, or smoke during work.
