Abstract
Inventia se refera la un procedeu de dibenz-/b,e/-oxepin-(11)-(6H)-onei din acid 2-fenoximetilbenzoic prin intermediul clorurii acide a acestuia în prezenta de clorura de aluminiu, caracterizata prin aceea ca nu se izoleaza clorura acidului 2-fenoximetil-benzoic, reactiile de clorurare si ciclizare au loc într-unul si acelasi solvent organic clorurat, la ciclizare se lucreaza în concentratii de cel mult 10% de clorura acida, cu exces molar de clorura de aluminiu care sa nu depaseasca 5%, ca solutia de clorura acida se introduce peste suspensia de clorura de aluminiu la o temperatura sub 10 degree C în cel mult 2h, perfectarea reactiei avînd loc la temperaturi de sub 20 degree C, iar complexul cetonei formate cu clorura de aluminiu se descompune cu o solutie de acid clorhidric, produsul înainte de izolarea sa din solvent purificîndu-se prin spalari repetate cu apa si solutie diluata de hidroxid de sodiu si apoi prin agitare cu carbune activ la cald.
