Method for preparing 1,4-butanediol dimethacrylate:
The invention discloses a method for preparing 1,4-butanediol dimethacrylate. Methyl methacrylate and 1,4-butanediol are taken as raw materials, and the method comprises the following steps of:
Reacting the methyl methacrylate with the 1,4-butanediol to prepare the product of 1,4-butanediol dimethacrylate with the purity of over 99.0 percent by adopting a reaction distillation ester exchange process in the presence of a catalyst and a polymerization inhibitor, wherein the catalyst is an organic tin catalyst; and the polymerization inhibitor is a composite polymerization inhibitor.
The invention has the advantages that:
The used catalyst is the organic tin catalyst, which has the advantages of small amount, high catalytic efficiency, short reaction time, mild reaction condition, convenience of post-treatment, no corrosion, reutilization and the like; and the used polymerization inhibitor is the composite polymerization inhibitor, which has the advantages of small amount, high-temperature resistance, good polymerization inhibiting effect, no influence on product color, convenience of post-treatment, no corrosion and the like.
Storage Temperature of 1,4-Butanediol diacrylate:
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
Preventive Measures of 1,4-Butanediol diacrylate:
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.
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.
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.
