L-glufosinate Salt Dispersion Process for Homogeneous Liquid Herbicides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of liquid herbicidal compositions of L-glufosinate salt is hindered by the formation of rock-solid lumps when it comes into contact with water, leading to reduced solubility, increased processing time, and equipment damage, making large-scale production cumbersome and costly.
Innovation Solution
A process involving the admixing of water with a dispersion comprising L-glufosinate salt and at least one organic solvent or liquid surfactant, without initial contact with water, to prevent rock-solid lump formation, thereby ensuring a homogeneous and efficient liquid herbicidal composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If L-glufosinate salt is contacted with water directly, then it should dissolve readily, but it forms rock-solid lumps with low solubility
Solution Approach 1:
The patent applies preliminary action by first forming a dispersion of L-glufosinate salt in an organic solvent before adding water. This preliminary dispersion step prevents the direct contact between L-glufosinate salt and water that causes rock-solid lump formation, thereby maintaining solubility while avoiding aggregation.
Solution Approach 2:
The patent uses an organic solvent as an intermediary substance between L-glufosinate salt and water. The organic solvent mediates the interaction by first dissolving the L-glufosinate salt to form a stable dispersion, which then mixes with water without forming rock-solid lumps, thus resolving the solubility-composition stability contradiction.
2Ease of manufacture
If L-glufosinate salt is mixed with water directly, then the composition can be prepared, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-forming a dispersion of L-glufosinate salt in an organic solvent before water addition. This preliminary step creates a stable intermediate formulation that mixes readily with water, significantly reducing the time and effort required for the overall composition preparation compared to direct mixing.
3Ease of manufacture
If L-glufosinate salt is mixed with water directly, then the composition can be prepared, but equipment damage occurs and investment increases
Solution Approach 1:
The patent applies preliminary action by first creating a dispersion of L-glufosinate salt in an organic solvent. This preliminary dispersion step prevents the formation of rock-solid lumps during water addition, thereby eliminating the mechanical stress and damage to mixing equipment that would otherwise occur during direct water mixing.
4Ease of manufacture
If L-glufosinate salt is mixed with water directly, then the composition can be prepared, but homogeneity is difficult to achieve
Solution Approach 1:
The patent applies preliminary action by first forming a uniform dispersion of L-glufosinate salt in an organic solvent. This preliminary dispersion ensures uniform distribution of the active ingredient before water addition, making it much easier to achieve a homogeneous final composition compared to direct water mixing where rock-solid lumps form and resist dissolution.
Solution Approach 2:
The patent uses an organic solvent as an intermediary to achieve better homogeneity. The organic solvent mediates the mixing process by first creating a uniform dispersion of L-glufosinate salt, which then integrates smoothly with water to produce a homogeneous liquid herbicidal composition without the aggregation problems of direct water mixing.
