In practice the processes “Reaction” and “Distillation” frequently will be executed consecutively, so that within the same equipment the starting materials react to the desired products and these products will be separated by distillation.
The combination of big stirred reactors made of glass-lined steel or stainless steel with distillation attachments made of borosilicate glass 3.3 represents an advantageous solution, which has been used successfully in the chemical and pharmceutical industries for many years. Specifically in the production of highly refined and highly pure products such as for example fine chemicals, plant protection agents, vitamins and pharmaceuticals, borosilicate glass 3.3 as an inert, metal‑free and highly corrosion resistant material has an important position. Overhead construction made of borosilicate glass 3.3 suitable for reactions and distillation/rectification can be realized for reactions vessels up 10.000l (stainless steel or glass-lined).
Vessel attachments are suitable for different processes, such as, for example:
Boiling under Reflux
Distillation
Hydro Distillation
Rectification
The plants are operated at atmospheric pressure or under vacuum mostly in batch but also in continuous mode.
The vessel attachments can be flexibly connected via PTFE bellows directly to or laterally offset from the vapour outlet of the reactor. Vessel attachments are mounted in separate structures next to the vessels.
