Solvents play an important role in crystallization processes. The screening/design of solvents for crystallization (crystallization solvents) is still of great concern in research and development. At present, most of the design/screening methods of crystallization solvents are still based on the trial-and-error approach. In this paper, the Grand Product Design (GPD) model is applied for the screening/design of crystallization solvents. The GPD-model includes process sub-model, property sub-model, quality sub-model, cost sub-model, pricing sub-model, economic sub-model and environmental sub-model as well as other factors such as company strategy, government policies and regulations. Solution strategies are given for three cases: solvent design for a fixed process, process design for a fixed solvent and simultaneous design of solvent and process. Taking 2-Mercapotobenzothiazole (MBT) as an example, the solvent design for a fixed (existing) process design is carried out by using the problem specific GPD-model, in which the GPD-model is formulated as Mixed-Integer Non-Linear Programming (MINLP) model with objective function, process sub-model, property sub-model, quality sub-model, pricing sub-model, cost sub-model, economic sub-model and environmental sub-model. The established MINLP model is then solved by the decomposition-based approach. Experiments are carried out to verify the candidate solvents, which is found to perform better in terms of product purity and recovery than the best-known solvents in use. In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6Application of 1843-21-6).
N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6) belongs to thiazole derivatives. The thiazole ring is notable as a component of the vitamin thiamine (B1). The pyridine-type nitrogen in the thiazole ring deactivates the ring for electrophilic substitution reactions, which is further reduced in acid due to protonation of the thiazole ring.Application of 1843-21-6
