AI Technical Summary
In the existing synthesis process of detoxifying quinine, when producing detoxifying quinine through transesterification, the lower alcohols exchanged are distilled off, resulting in high levels of methanol impurities in the recovered methanol, making it difficult to reuse directly and affecting product purity.
The detoxified quinolone synthesis unit includes a reaction tower, a desolventizing vessel, a crystallizing vessel, a centrifuge, and a wet product storage tank. Lower alcohols are recovered through a condenser, and combined with vacuum desolventizing and recrystallization technology, the purity of the alcohol and the quality of the product are improved.
It effectively improves the recovery purity of lower alcohols, overcomes the problem of high methanol impurities in existing technologies, and produces a higher purity detoxifying quinine product.
