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. (wikipedia.org)
But to make it clear, do you think the simple use of anhydrous calcium chloride and glacial acetic acid is sufficient to produce acetic anhydride? (sciencemadness.org)
The patent from 1927 claims "the production of acetic anhydride from a mixture of sodium metaphosphate, anhydrous sodium acetate, and infusorial earth moistened with glacial acetic acid, the reaction being effected at 150-180°C". Sounds too good to be true, but it could work, and yield wouldn't really be an issue considering the requirements. (sciencemadness.org)
That patent (see attachment) also claims that acetic anhydride can be produced by heating a mixture of glacial acetic acid and sodium hexametaphosphate which doesn't work as far as I can tell. (sciencemadness.org)
PMAO contains succinic anhydride units that are reactive towards the oleylamine species present on the Cs 4 PbBr 6 nanocrystals' surface and produces polysuccinamic acid, which, in turn, triggers the Cs 4 PbBr 6 to CsPbBr 3 conversion. (rsc.org)

Several acid anhydrides are known for their sensitizing and irritative properties. (cdc.gov)
Acid anhydrides are low-molecular-weight (LMW) chemicals that have been used in industry for more than 50 years as curing agents in the produc- tion of epoxy and alkyd resins and in the manufacture of the plasticizer dioctyl phthalate. (cdc.gov)
The functional RCOOCOR' group endows acid anhydrides with the reactivity needed for these applications, but this reactivity is most probably also responsible for the irritative and sensitizing properties of these LMW chemicals (Bernstein et al. (cdc.gov)
1998). Tri- mellitic anhydride (TMA) is a model compound among the acid anhydrides. (cdc.gov)
However, for later use in cleaners and detergents, clear (meaning polymer-free) and less dark colored alkenyl succinic anhydride (ASA) were needed. (wikipedia.org)

Succinic anhydrides3
Alkenyl succinic anhydrides (ASA) are derivatives of succinic anhydrides. (wikipedia.org)
The use of alkenylsuccinic anhydrides to hydrophobize cellulose-based (cotton) textiles (first patented in 1959) and the transfer of this concept to the hydrophobization of paper using iso-octadecenyl succinic anhydrides (C18-ASA) in 1963 required liquid, particle-free colours with a colour as light as possible. (wikipedia.org)
After initial difficulties in using ASA for paper sizing (particularly the rapid hydrolysis to alkenyl succinic acids and the formation of poorly soluble calcium salts in hard water and deposits in the paper machine), process parameters could be adjusted to make alkenyl succinic anhydrides the most important sizing agents in the US.
