Remarkably, this facility is the world's second plant to manufacture pAP from Nitrobenzene, the firm said. pAP is used for producing Paracetamol, amongst other prescription drugs

Producing pAP from Nitrobenzene, as against its manufacturing from Para Nitro Chloro Benzene (PNCB), offers several significant benefits. The PNCB method is marked by substantial effluent production, while the Nitrobenzene approach aligns with green chemistry principles, generating zero effluent.

Notably, the PNCB process results in various chlorine-based contaminants, notably Para Chloro Aniline (PCA), a substance facing increasing restrictions due to its detrimental effects. In contrast, the Nitrobenzene method avoids using any chlorine-based ingredients, ensuring a product free from PCA and other harmful impurities.

To ensure the plant's stability and product quality, the company conducted over 100 batch runs while transitioning to continuous production mode. The switch from batch to continuous production necessitated adjustments in vessel alignment, piping, and instrumentation, a process that spanned six months.

Upon initiating continuous mode, the company said it achieved success, stabilising the plant and meeting its previously targeted throughput and quality standards.

Talking about this achievement, Abhishek Javeri, MD, Sadhana Nitro Chem said, “We've garnered product approvals from customers in regions like Europe, Japan, Turkey, among others and continuously working towards adding more customer approvals to our portfolio. We are optimistic that subsequent scaling efforts will be significantly more efficient, both in terms of time, space, and capital expenditure."
