The role of azeotropic distillate for the formation of carboxylic anhydrides
Points noted, and will reduce such writing to prevents readers eyes rolling over like a cheap glazed donut. Apologies, but its a learning curb.
One point I will make is, I wasnt implying DS conditions for the formation of acetyl halides, just made mention of them, as they are the usual route, I believe, to the formation of alkanoic anhydrides.
I will revise, and present questions that are more direct, and thanks for the heads up.

Dear Beatle, 1). Please, just ask a question in the most laconic way, you can because nobody reads long texts with pleasure. 2). The order of water removing yield by azeotropy is: xylene (30% w/w), toluene (20% w/w), benzene (9% w/w). Furthermore, benzene is highly toxic and carcinogenic. 3). You do not need to add toluene because chlorinated agents are usually liquids that are added in excess and thus, adequate solvents. 4). Besides, there is no formation of water during acyl chlorides preparation with the described reagents. 5). The byproducts of acyl chlorides preparation are usually removed by distillation with the help of a Claisen still head that is connected with flask’s condenser. Instead, you can use a Dean Stark apparatus but this needs enough experience. 6). I fully apologize if not having precisely answered and if not having well understood your questions but I didn’t read you text, in detail because it is too long. Sincerely yours pgk
