basics of technology

Aceclofenac drugs are widely used in the global therapeutic practice of inflammatory and painful conditions for the treatment of osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis in various dosage forms. The basics of the technology of domestic industrial batch production of aceclofenac with a capacity of 110 t/year for the production of a number of effective medicines have been developed. A five-stage production process is proposed that will allow the production of a domestic product with a high yield (~ 91%) from commercially available reagents.

The basis of the production technology of the diclofenac substance, which consists of five main technological stages, is justified and proposed. The proposed technological aspects of diclofenac substance production allow obtaining the target product with a total yield of 61%. Material calculations were carried out to obtain 1 ton of the final diclofenac substance. The numbers of necessary technological equipment are selected, and a basic technological scheme for the production of diclofenac is proposed.
