Metathesized Polyol Esters for Petroleum Petrolatum Substitution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The non-renewable nature of petroleum-based petrolatum and wax compositions necessitates the development of alternative materials that mimic their properties without relying on petroleum-derived sources.
Innovation Solution
The creation of petrolatum-like compositions using metathesized unsaturated polyol esters, which can be hydrogenated to achieve properties similar to petroleum-derived petrolatum, including cone penetration, congealing point, and viscosity, allowing for their use in various applications as substitutes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If petroleum-based petrolatum and wax compositions are used, then desired properties (viscosity, congealing point, cone penetration) are achieved, but reliance on non-renewable petroleum resources occurs
Solution Approach 1:
The patent applies parameter changes by systematically adjusting the degree of hydrogenation (measured by iodine value) and the extent of oligomerization of metathesized polyol esters to match the physical properties of petroleum-derived petrolatum. By controlling these parameters, the invention achieves petrolatum-like viscosity, congealing point, and cone penetration while using renewable vegetable oil feedstocks instead of non-renewable petroleum resources.
2Reliability
If metathesized unsaturated polyol esters are hydrogenated to achieve petrolatum-like properties, then desired physical properties (viscosity, congealing point) are obtained, but additional processing steps are required
Solution Approach 1:
The patent applies preliminary action by performing metathesis reaction on unsaturated polyol esters before hydrogenation to create a precursor material with controlled oligomerization. This preliminary metathesis step prepares the molecular structure in advance, so that subsequent hydrogenation more efficiently produces the desired petrolatum-like properties with fewer additional processing steps.
