| Skin, Eye, and Respiratory Irritations | Methacrylates ... produce slight to moderate skin and eye irritation ... depending upon volatility, these materials also may be sensory irritants. /Methacrylic acid & derivatives/ |
| Lagerbedingungen | Temp during storage must be kept low to minimize formation of peroxides and other oxidation products. ... Storage temp below 30 °C are recommended for the polyfunctional methacrylates. ... The methacrylate monomers should not be stored for longer than one year. Shorter storage times are recommended for the aminomethacrylates, ie, three months, and the polyfunctional methacrylates, ie, six months. Many of these cmpd are sensitive to UV light and should, therefore, be stored in the dark. The methacrylic esters may be stored in mild steel, stainless steel, or aluminum. /Methacrylic acid & derivatives/ |
| Preventive Measures | ... Hazard is the generation of considerable exothermic heat in some of the reactions, so that high pressures & temp may develop. This danger ... should be borne in mind when designing plant. Awareness of the dangers and of good engineering design are essential to safety. Employees should be instructed about the necessity of cleansing the skin if it is contaminated by materials which are irritants or skin-absorbed. With careful design, however, and complete enclosure of those processes where toxic chemicals or intermediates occur, dangerous exposures can be avoided. /Acrylic acid & derivatives/SRP: 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.SRP: 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. |

Anwendungen & Verwendung
Beschreibung
Cyclohexyl Methacrylate (CHMA) is a very useful starting material for chemical synthesis since it easily undergoes addition reactions with a wide range of organic and inorganic compounds. The compound is an ester of Methacrylic acid and is used as a raw material component in synthesizing polymers. It is a monofunctional monomer consisting of a methacrylate group with a characteristic high reactivity and a cyclic hydrophobic group. Copolymers of CHMA can be prepared with (meth)acrylic acid and its salts, amides, and esters and with (meth)acrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, unsaturated polyesters, and drying oils, etc.
