Triazine Derivatives Synthesis via Novel Intermediates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current processes for producing symmetrical triazine derivatives are inefficient due to the large number of steps and the need for intermediate purification, resulting in products with less than ideal purity, color, odor, and stability, which increases production costs.
Innovation Solution
The development of novel intermediates and their synthesis processes that allow for the preparation of triazine derivatives with high purity and high yields, using specific reaction schemes and solvents to minimize steps and eliminate the need for intermediate purification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the known processes for preparing triazines are used, then the triazine derivatives can be produced, but the number of steps is large and intermediate purification is required, resulting in lower efficiency and higher production costs
Solution Approach 1:
The patent combines multiple synthesis steps into a single step by using a novel intermediate compound that contains all necessary functional groups (chloro group and carbonyl group) in one molecule. This allows both substitution reactions to occur in one operation, eliminating the need for separate steps and intermediate purifications required by conventional methods.
Solution Approach 2:
The patent performs preliminary action by pre-synthesizing a novel intermediate compound with pre-installed functional groups (chloro group at position 2 and carbonyl group at position 4) before the final substitution reactions. This preliminary preparation allows the final triazine synthesis to proceed in fewer steps without requiring multiple separate reactions and purifications.
2Manufacturing precision
If the known processes for preparing triazines are used, then the triazine derivatives can be produced, but the products have less than ideal purity, color, odor and stability
Solution Approach 1:
The patent extracts and eliminates the problematic intermediate purification steps from the synthesis process. By designing a route where the novel intermediate is formed in one step and directly used without isolation, the method removes the source of impurity accumulation while maintaining high product purity through the selective reactivity of the novel intermediate's functional groups.
3Ease of manufacture
If the known processes for preparing triazines are used, then the triazine derivatives can be produced, but the production costs increase due to the large number of steps and purification requirements
Solution Approach 1:
The patent merges multiple synthesis operations into a single step, thereby reducing the cumulative cost of multiple purifications, reagents, and energy consumption. The novel intermediate's dual functional groups enable simultaneous reactions that would otherwise require separate steps, directly reducing production costs while simplifying the manufacturing process.
