Abstract
A pinene-derived diisocyanate compound, a process for forming a pinene-derived polyurethane, and an article of manufacture that includes the polyurethane are disclosed. The process for forming the polyurethane includes forming a pinene-derived diisocyanate compound, and reacting the pinene-derived diisocyanate compound with a polyol in a polymerization compound.
Claims12
A process of forming a polyurethane, comprising:
- forming a pinene-derived diisocyanate compound, wherein the forming comprises:
- obtaining pinene;
- oxidizing the pinene to form a pinene-derived ketone compound;
- converting the pinene-derived ketone compound to a diamine compound;
- and
- reacting the diamine compound with phosgene;
- and
- reacting the pinene-derived diisocyanate compound with a polyol in a polymerization reaction.
