Succinic anhydride, is an organic compound with the molecular formula (CH 2 CO) 2 O. This colorless solid is the acid anhydride of succinic acid. Preparation.
The patent describes the reaction of the alkenes with excess maleic anhydride at 200 °C in an autoclave. The excess alkene is removed by distillation in vacuo, the resulting alkenyl succinic anhydride hydrolyzed with dilute sodium hydroxide solution and the disodium salt reacted with an acid to achieve an alkenebutanedioic acid.
PolyAnalytik Inc. is a Canadian contract research organization, headquartered in London, Ontario, Established in 2007, PolyAnalytik specializing in the analysis of polymers, bio-polymers & small molecules, offering a wide range of services including pre-clinical studies, bio-processing, and purification.
In 2010, hydrophobically modified ε-polylysine was synthesized by reacting EPL with octenyl succinic anhydride (OSA). [14] It was found that OSA-g-EPLs had glass transition temperatures lower than EPL. They were able to form polymer micelles in water and to lower the surface tension of water, confirming their amphiphilic properties.
A common way to synthesize an NHS-activated acid is to mix NHS with the desired carboxylic acid and a small amount of an organic base in an anhydrous solvent. A coupling reagent such as dicyclohexylcarbodiimide (DCC) or 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) is then added to form a highly reactive activated acid intermediate.

Succinic acid (/ s ə k ˈ s ɪ n ɪ k /) is a dicarboxylic acid with the chemical formula (CH 2) 2 (CO 2 H) 2. [5] In living organisms, succinic acid takes the form of an anion, succinate, which has multiple biological roles as a metabolic intermediate being converted into fumarate by the enzyme succinate dehydrogenase in complex 2 of the electron transport chain which is involved in making ...
