Abstract
Methods of producing plant polyols from plant oils include reacting a plant oil with a designed reactant having one or more nucleophilic functional groups and one or more active hydrogen functional groups in the presence of an addition reaction catalyst in a single reaction step. The resultant polyols may be directly reacted with polyisocyanates to produce polyurethanes.
Claims26
A process of making a modified plant-based polyol comprising:
- a) providing:
- i) at least one plant oil having at least one carbon-carbon double bond;
- and
- ii) a reactant having at least one nucleophilic functional group and at least one active hydrogen functional group;
- and
- b) reacting the reactant with the plant oil at the plant oil carbon-carbon double bond in the presence of an addition reaction catalyst selected from the group consisting of halogens, hydrohalogens and combinations thereof.
A reaction product of at least one plant oil having at least one a carbon-carbon double bond with a reactant having at least one nucleophilic functional group and at least one active hydrogen functional group, the reaction performed in the presence of an addition reaction catalyst selected from the group consisting of halogens, hydrohalogens and combinations thereof, wherein the reactant reacts with the at least one carbon-carbon double bond of the at least one plant oil, so as to generate a polyol reaction product.
