Bis(prop-2-enyl) benzene-1,2-dicarboxylate

Bis(prop-2-enyl) benzene-1,2-dicarboxylate is an organic chemical compound with the molecular formula C14H14O4 and CAS number 131-17-9. This substance is a diester derived from phthalic acid (benzene-1,2-dicarboxylic acid) and allyl alcohol. With a molecular weight of 246.26 g/mol, it belongs to the family of phthalate esters and is classified as moderately hazardous with warning-level toxicity and environmental concerns.

Bis(prop-2-enyl) benzene-1,2-dicarboxylate is typically a colorless to pale yellow liquid at room temperature with a characteristic ester odor. The compound has a molecular weight of 246.26 g/mol and contains allyl ester functional groups that make it reactive to polymerization. It has limited water solubility due to its organic nature but is soluble in most organic solvents. The presence of double bonds in the allyl groups makes it susceptible to oxidation and polymerization reactions.

Bis(prop-2-enyl) benzene-1,2-dicarboxylate is primarily used as a crosslinking agent and plasticizer in polymer applications. Its allyl groups enable crosslinking reactions in thermosetting resins, making it valuable in the production of durable plastic materials. The compound is also utilized in the manufacture of specialty coatings, adhesives, and composite materials where enhanced mechanical properties and chemical resistance are required. Its phthalate structure provides plasticizing effects while the allyl functionality adds crosslinking capability.

Bis(prop-2-enyl) benzene-1,2-dicarboxylate should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing due to its Acute Tox. 4 classification. Work in well-ventilated areas or under fume extraction to avoid inhalation exposure. Avoid skin and eye contact, and prevent release to the environment due to its aquatic toxicity classification. Use proper handling procedures to prevent spills and ensure all personnel are trained in safe chemical handling practices.

Bis(prop-2-enyl) benzene-1,2-dicarboxylate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Due to the reactive allyl groups, avoid storage near strong oxidizers, acids, or bases that could initiate polymerization. Keep containers upright and properly labeled according to GHS requirements with warning pictograms GHS07 and GHS09. Store away from environmental release points due to its aquatic toxicity classification.

In case of skin contact with bis(prop-2-enyl) benzene-1,2-dicarboxylate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for 15-20 minutes and remove contact lenses if present. If inhaled, move to fresh air immediately. If ingested, do not induce vomiting and seek medical attention. Always consult a physician if symptoms develop or persist after exposure.

Bis(prop-2-enyl) benzene-1,2-dicarboxylate must be disposed of through licensed hazardous waste disposal facilities in accordance with local, national, and EU waste regulations. Due to its environmental hazard classification (Aquatic Acute 1, Aquatic Chronic 1), it cannot be discharged to sewers or the environment. Waste should be collected in appropriate containers, properly labeled, and handled by certified waste management companies. Small quantities should never be poured down drains or disposed of with regular waste.

Bis(prop-2-enyl) benzene-1,2-dicarboxylate is classified as ADR Class 9 (Miscellaneous dangerous substances), Packing Group III for transport purposes. This classification requires appropriate packaging, labeling, and documentation for road transport within Europe. Packages must be properly marked with the substance name, UN number, and hazard labels. Transport vehicles should carry appropriate emergency equipment and drivers must have ADR certification. Proper shipping papers and emergency response information must accompany shipments.

Bis(prop-2-enyl) benzene-1,2-dicarboxylate is subject to EU REACH regulation requiring registration for import/manufacture above certain tonnages. It is classified under CLP regulation with specific hazard classifications (Acute Tox. 4, Aquatic Acute 1, Aquatic Chronic 1) requiring appropriate labeling and safety data sheets. The substance is not currently listed as SVHC under REACH. Users must comply with occupational exposure limits and environmental protection measures due to its toxicity classification.
