Cobalt Compound Synthesis for Feed Supplements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cobalt compounds used in feed supplements for livestock are often toxic, poorly bioavailable, or insoluble, limiting their effectiveness in preventing Vitamin B12 deficiency in ruminant animals.
Innovation Solution
A method involving dissolving cobalt acetate tetrahydrate in water, adding a selected acid, sonicating the mixture to form fine crystals, and separating the cobalt compound, which enhances bioavailability without requiring high temperatures or grinding, using acids like lactic, propionic, or gluconic acids to produce cobalt lactate, propionate, or gluconate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cobalt carbonate is used as a feed supplement, then it has been used for many years, but a significant portion is not taken up easily by microorganisms in the rumen
Solution Approach 1:
The patent changes the chemical parameters of cobalt compounds by producing cobalt lactate, cobalt propionate, cobalt gluconate, and cobalt heptogluconate through specific chemical reactions. These parameter changes result in compounds with improved solubility and bioavailability compared to traditional cobalt carbonate, directly addressing the uptake efficiency problem.
2Reliability
If cobalt chloride is used, then it provides cobalt for Vitamin B12 synthesis, but it releases hydrogen chloride which deactivates enzymes and is an irritant
Solution Approach 1:
The patent converts the harmful hydrogen chloride release of cobalt chloride into beneficial forms by using alternative cobalt compounds (cobalt lactate, cobalt propionate, cobalt gluconate, cobalt heptogluconate) that provide cobalt for Vitamin B12 synthesis without releasing harmful hydrogen chloride, thus eliminating the harmful effect while maintaining the beneficial function.
3Reliability
If cobalt oxide or cobalt hydroxide is used, then it provides cobalt, but it is very insoluble at physiological temperatures and not useful in feed supplements
Solution Approach 1:
The patent changes the solubility parameter of cobalt compounds by producing soluble forms (cobalt lactate, cobalt propionate, cobalt gluconate, cobalt heptogluconate) through specific chemical reactions with organic acids. This parameter change transforms insoluble cobalt compounds into soluble forms that can be effectively utilized by microorganisms in the rumen.
4Reliability
If high temperatures, high magnetic fields or grinding are used to improve bioavailability, then the relative surface area increases, but the process complexity and energy consumption increase
Solution Approach 1:
The patent changes the chemical parameters of cobalt compounds through specific chemical reactions with organic acids (lactic, propionic, gluconic, heptogluconic acids) to produce soluble cobalt compounds. This chemical parameter change improves bioavailability and relative surface area without requiring high temperatures, high magnetic fields, or grinding, thus avoiding increased process complexity.
