Bisphenol A Markers for Fuel Digital Coding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for additional marker compounds to enhance the digital marking systems for liquid hydrocarbons and other fuels, as existing markers may not provide sufficient coding capacity or detectability.
Innovation Solution
The method involves adding specific compounds with the formula (I) to petroleum hydrocarbons or biologically derived fuels, where R1 and R2 are hydrogen or C1-C4 alkyl groups, and G represents hydrogen or C1-C18 alkyl and alkoxy substituents, to create unique markers that can be detected using chromatographic techniques and mass spectral analysis, allowing for coded identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional marker compounds are introduced to enhance digital marking systems, then the coding capacity and detection capabilities are improved, but the complexity of the marking system increases
Solution Approach 1:
The patent introduces multiple distinct marker compounds (compounds of formula I with different R1, R2, and G substituents) that can be used in combination to form digital marking codes. Each compound acts as a separate element that can be selectively added to fuels, allowing for multiple code combinations without requiring a single complex marker system.
Solution Approach 2:
The patent utilizes variations in chemical parameters (substituents R1, R2, and G on the bisphenol A core structure) to create distinct marker compounds. By changing these chemical parameters, different markers are generated that can be detected through mass spectrometry or other analytical techniques, enabling digital coding capacity while maintaining individual compound simplicity.
2Measurement precision
If multiple marker compounds are used to form digital codes, then the detection capability and identification accuracy are improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent replaces complex multi-parameter measurement systems with mass spectrometry or other analytical techniques that can selectively detect and quantify specific marker compounds based on their unique mass-to-charge ratios or other detectable properties. This substitution simplifies the measurement process while maintaining high precision for detecting multiple markers simultaneously.
