WebSuccinic anhydride is not expected to volatilize from dry soil surfaces based upon its vapor pressure. If released into water, succinic anhydride will rapidly hydrolyze; the half-life of succinic anhydride in water is 4.3 minutes at 25 °C. Bioconcentration of succinic anhydride in aquatic organisms is unlikely due to its rapid hydrolysis. WebSuccinic Anhydride [CAS: 108-30-5] is a product of the dehydration reaction of succinic acid. When succinic acid is dehydrated, it loses the elements of water (H 2 O), leaving a lone oxygen on the molecule in need of an electron acceptor to balance its charge. That charged oxygen atom then bonds to the other end of the molecule, forming the ...
