Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional methods are used to produce sulfur-containing epoxy compound, then the production process can be completed, but scum-like insoluble matter is generated causing pipe clogging and production troubles
Solution Approach 1:
The invention changes the chemical parameters of the reaction system by using a mixed solvent containing both organic solvent and aqueous solution of basic compound, with controlled temperature between -10°C to 50°C. This parameter change prevents the formation of scum-like insoluble matter while maintaining production continuity
Solution Approach 2:
The mixed solvent acts as an intermediary medium between the sulfur-containing halohydrin compound and the basic compound. The organic solvent component prevents direct contact that would generate insoluble matter, while still allowing the化学反应 to proceed efficiently
2Ease of manufacture
If sulfur-containing halohydrin compound is reacted with aqueous solution of basic compound, then the sulfur-containing epoxy compound can be produced, but scum-like insoluble matter is generated
Solution Approach 1:
The organic solvent in the mixed solvent acts as an intermediary that prevents direct harmful interaction between the sulfur-containing halohydrin compound and aqueous basic compound, while still allowing the desired化学反应 to proceed efficiently
Solution Approach 2:
By changing the solvent system from pure aqueous to mixed organic-aqueous and controlling temperature parameters, the invention maintains reaction efficiency while eliminating the generation of scum-like insoluble matter
