Тhe technology basis of diclofenac substance production
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.
